Killexams : Questions and Answers from the ‘Car Doctor’

Q. First time reaching out. I have a 2013 Honda Civic. Lately, I have been hearing a weird sound from the rear of the car. Almost sounds as if something is banging around in the trunk, but my trunk is empty. Thought it was a loose pipe of some sort, but after checking quickly under the car, I didn’t see anything obvious hanging. Could it be the gas tank at all?

A. Great idea to look in the truck I have seen loose spare tires, jacks, lug wrenches, soda and soup cans. At this point the car needs to go on a lift and look for loose or worn suspension bushings and worn strut mounts. The issue could also be a loose baffle in the muffler. It shouldn’t take more than 30 minutes to find the source of the noise and to rule out if it is a safety issue.

Q. I own a 2022 Subaru Forester when I turn off the car there is a noise that starts. I recorded a video and had the Subaru dealer look at it and they tell that is nothing, they didn’t find anything with my car. Is it nothing?

A. Great idea to record the noise. More than likely the noise is the heat shield that surrounds the exhaust system expanding and contracting as it cools. In the past I have seen manufacturers add shims to fill the gap and quiet the noise. Where the car is new I would provide the dealer a little time to see if Subaru has come up with a fix to quiet the noise.

Q. My question is how long does diesel fuel stay fresh in a car? Can I add Stabil to diesel or is that for gas engines only?

A. I have seen untreated diesel fuel last six months or more. Over time untreated diesel fuel will become sludgy and can even grow an algae like substance. Stabil does have a product specifically for diesel engines and if are storing a diesel-powered vehicle for anytime it would be best to use a fuel additive.

Q. I have a 2018 Nissan Murano SL with approximately 38,000 miles. I have bled and flushed brakes in the past before but decided to try using a pressure bleeder. I read in the service manual to either disconnect the ABS (anti-lock brakes) control unit or negative battery cable when bleeding brakes. I’d like to not disconnect battery, so I attempted to disconnect the ABS module, which is near impossible to reach without removing parts. Is it absolutely necessary that the ABS module be disconnected, will there be any adverse effects? In the past on older vehicles I never had an issue but I’m unsure how to proceed with these newer vehicles.

A. Nissan is very specific to disconnect the battery of the module to prevent any damage to the anti-lock brake system. ABS brake systems will sometimes need to use a scan tool to cycle the ABS system to remove any air. Changing brake fluid is a great idea every three to four years, but as a bit of a cheat, siphon out some (no all) of the fluid from the master cylinder. If you do this at each oil change you will “freshen” up the brake fluid.

Q. I have a 2022 Infiniti QX 60. Bought brand new with 3000 miles. With my vehicle running, pulling into a parking space that is on an incline, foot on the brake pedal, and then placed into park. With the foot still on the brake pedal, turn off the motor. The vehicle will roll back approximately 2 to 3 inches after you remove your foot from the brake pedal. The dealership has said they’ve tested other new vehicles on the lot and that they all do this. This is a scary situation as someone may be exiting from the other doors, you still have your foot on the brake, they open the door and can be in a tight situation where the car will roll backwards, as you let your foot off the brake pedal. Or you could open the door yourself and an object could be next to the side of your driver’s door. I Got my driver’s license in 1965, and never had any other vehicle that did this or it was in one that did this. Having worked on cars and knowing what 1-8-4-3-6-5-7-2 stands for, helps when you’re talking to the mechanics in the shop. I still have my 1970 AMX race car. The standard answer is they all do it which I don’t agree with. Appreciate any help that you can provide me.

A. The 2022 Infiniti QX has the new nine-speed automatic transmission that replaced the less than desirable CVT transmission. I agree that three inches of roll back is too much, and I would personally want to test another vehicle for comparison. Infiniti is a little cheeky about this. In the owner’s manual it states that you should always apply the parking brake when stopped and the “park” position is not a substitute for the parking brake. At this point I haven’t been able to locate any technical bulletins about this issue. If in fact “they all do it” it may be an undesirable characteristic of this transmission. By the way in my opinion the AMC AMX is one of the most underappreciated muscle cars of its time. Readers if you are wondering, 1-8-4-3-6-5-7-2 is the firing order for a small block Chevy engine.

Killexams : Plastics and Human Rights: Questions and Answers

Plastic production, use, and disposal have significant impacts on human rights. Plastics contain toxic chemical additives, which can pose significant threats to human health. Because they are made of fossil fuels, plastics are driving the climate crisis, which in turn threatens human rights.

On November 28, 2022, countries around the world will begin to negotiate a new Global Plastics Treaty. The negotiations are based on a resolution by the United Nations Environment Assembly, mandating the creation of a legally binding instrument by the end of 2024 to end plastic pollution. The world is drowning in plastic, and the creation of this mandate recognizes the urgency of addressing the problem for the benefit of human beings and the environment. As negotiations proceed, the countries involved should ensure that the treaty addresses plastics in a way that protects human rights.

Each year, more than 300 million metric tons of plastic is created. Many plastic products are single use, cannot be recycled, and remain in the environment for decades or centuries. Only 9 percent of plastic ever produced has been recycled, while the remaining plastic waste is dumped, landfilled, incinerated, or litters the environment. Of all plastic produced, 79 percent has accumulated in landfills, informal dumpsites, or the natural environment, and 12 percent has been incinerated.  

This document examines the ways that plastic production, use, and disposal threaten human rights, and why governments should take immediate steps to limit plastics to meet their human rights obligations.

Why are plastics a human rights issue?

The production, use, and disposal of plastic generates harmful effects on human health and the environment. International human rights law obligates governments to address such harms and to respect, protect, and fulfill the rights to health, water, access to information, and a healthy environment.

The plastic life cycle begins with oil and gas extraction. Ninety-nine percent of plastics are made of fossil fuels, including oil and gas, and plastics and petrochemicals are estimated to drive 30 percent of the growth in oil demand by 2030 and nearly half of the growth in oil demand by 2050. Oil and gas production can emit toxic chemicals through drilling operations, mechanical equipment, storage tanks, and transportation of fuels. For example, benzene, a carcinogenic compound, is often emitted from petroleum operations into the water, soil, and air, which can threaten the health of nearby communities.

Plastic production and manufacturing turns fossil fuel raw materials and chemical additives into plastic that can be used to make packaging, consumer products, and other goods. The refining and manufacturing processes pose threats to human rights, particularly to communities living close to petrochemical production facilities and refineries, by emitting harmful pollutants into the air and water. Refineries and plastic production facilities are often located in low-income and marginalized communities and communities of color, which are disproportionately impacted by pollution and environmental harm.

Plastic products are then used by consumers and in industrial activities. Some studies have linked ingested plastic particles with impacts on cell function, chronic inflammation, and disruptions to the endocrine system. Currently, plastic producers around the world are not required to identify chemical additives in their products, so consumers are not able to access information about the chemical makeup of plastics and their potential impacts on their health.

After use, some plastic is recycled and returns to the plastic production stage. Most plastic is disposed of in formal landfill or informal dumpsites or is incinerated at an industrial facility or disposed of through open burning. When plastic is dumped or landfilled, it naturally breaks down into microplastics, polluting the soil, water, air, wildlife, and human bodies. Methods to dispose of plastic waste, including incineration, contribute to short-term and long-term health effects as harmful chemicals and particulate matter are released into the air.

Why are plastics an increasing problem?

Since the 1950s, plastic has evolved from being a less common, multiuse material to being ubiquitous in modern equipment, packaging, textiles, and other common goods. Global annual plastic production has soared from two million metric tons in 1950 to 380 million metric tons in 2015, a 190-fold increase.

Not only has plastic use increased over accurate decades, but plastic production is also projected to triple from 2015 to 2060. Plans to scale up the plastic industry are largely driven by the world’s largest oil and gas producing companies, alongside consumer goods companies. As countries around the world begin to address their dependence on oil and gas as a source of energy, fossil fuel producing companies are increasing investments in plastic and petrochemical production, as well as increasing capacity to make plastic, as an alternative area of growth.

The same fossil fuel companies have led decades-long disinformation campaigns to advance the myth that plastic is recyclable, while internal industry documents as early as the 1970s show that plastic producers knew recycling wasn’t an acceptable solution.

How do plastics contribute to the climate crisis?

Plastics are a major contributor to climate change. The extraction, transport, and refining of oil and gas, their conversation into the raw materials for plastics, and the transportation and burning of plastic waste all emit significant quantities of greenhouse gases, which are contributing to the climate crisis. In 2019, global production, disposal, and incineration of plastic emitted 850 million metric tons of CO2e, or carbon dioxide equivalent, as much as would be emitted by 189 500-Megawatt coal power plants.

If plastic use continues to grow as projected, by 2050 the greenhouse gas emissions from plastic production and incineration will reach 15 percent of the global carbon budget, making global climate goals extremely difficult, if not impossible, to reach.

What makes plastics toxic?

Chemical additives are added to plastics during production to change or enhance performance, functionality, or other properties of the plastic production. While chemical additives provide plastic products qualities that make them useful, they can also be toxic environmental pollutants and harmful to human health. For example, phthalates, bisphenol A (BPA), and per- and polyfluoroalkyl substances (PFAS) are common chemical additives in plastic that are known to harm human health and are linked with cancer and harm to reproductive systems.

How do plastics affect at-risk groups and marginalized communities? 

Exposure to toxins in plastic products – and emitted during disposal – can have particular and unique impacts on children, women, and pregnant and older people due to biological factors. Women exposed to endocrine disrupting chemicals, including BPA, are at increased risk of polycystic ovarian syndrome and recurrent miscarriages. Exposure to these chemicals prior to and during childbearing years can result in increased likelihood of children being born with disabilities. Children, when exposed to the same levels of air pollution as adults, are at risk for more acute health impacts due to their rapid development. Children growing up in areas with high levels of industrial air pollution are likely to have reduced lung function. Exposure to chemicals may lead to harmful effects that do not appear until puberty or adulthood.

Older people are also particularly affected. As the human body ages, changes in organ functioning may make it harder for people’s bodies to process environmental pollutants, including toxins emitted during plastic recycling. A slower metabolism, coupled with earlier-life exposure, can lead to pollutants remaining in older people’s bodies for a longer period than for younger adults, increasing their exposure to toxins.

Isn’t recycling the solution to the plastics crisis?

No. While recycling is often portrayed as a positive, environmentally friendly practice, when plastic is recycled, it releases pollutants and toxins into local environments, threatening the health of those working in and living nearby recycling facilities.

Human Rights Watch documented that plastic recycling in Turkey – the largest recipient of plastic waste exports from the European Union – is harming people’s health. Pollutants and toxins emitted from recycling affect workers, including children, and people living near recycling facilities. Workers and residents of neighboring communities described respiratory problems, severe headaches, skin ailments, lack of protective equipment, and little to no access to medical treatment for occupational illnesses. Many of the facilities Human Rights Watch visited were located dangerously close to homes, in contravention of Turkish laws and environmental regulations.

Why is plastic waste being shipped around the world?

Countries in the Global North, including the United States, Canada, Japan, United Kingdom, and European Union member states, have routinely exported their plastic waste as “recycling” to countries with weak or nonexistent environmental regulations, low labor costs, and little government oversight on environmental and labor rights violations. They do so because they lack the physical infrastructure to recycle it domestically, and profits can be made by selling it to companies in other countries for processing. In this way, they externalize the health, environmental, and economic costs of their high consumption economies instead of reducing levels of consumption or investing in waste management.

For decades, China was the world's single largest importer of plastic waste, importing approximately 45 percent of global plastic waste from 1992 to 2016. Due to the high environmental impacts of plastic waste, the Chinese government created what it calls its National Sword Policy in January 2018, which banned the import of most plastic waste. So exporting countries have searched for new places to send their waste, and Malaysia, Indonesia, Vietnam, and Turkey have recently become key destinations for the world’s plastic waste exports.

What is the Global Plastics Treaty?

In March 2022, the United Nations Environment Assembly agreed to draft a multilateral environmental treaty addressing the global plastics crisis. The mandate paves the way for countries to establish a legally binding instrument to address the impacts of plastics throughout their lifecycle. 

What are some key steps governments can take to ensure the Global Plastics Treaty enhances respect for human rights?

Governments in the UN Environmental Assembly should negotiate and adopt a plastics treaty that protects and respects human rights. A comprehensive and rights-respecting Global Plastics Treaty requires the meaningful participation of civil society. Such participation should include representation from people most at risk from the harm of plastic production, use, and disposal, including Indigenous people, people with disabilities, older people, children and young people, women, waste pickers and workers in the informal economy, labor unions, minorities, and people living in poverty.

Some key elements of a global plastics treaty that would protect human rights are requirements to:

  1. Take steps to decrease the production and consumption of plastic.
  2. End the production of unnecessary virgin plastic.
  3. Increase transparency about chemical additives in plastics and limit the addition of harmful chemical additives in plastic products.
  4. Protect the rights to health, water, food, and a healthy environment of at-risk populations and marginalized communities affected by plastic pollution.

Killexams : Questions and Answers from the ‘Car Doctor’

Q. I have a 1998 Ford Crown Victoria that is losing coolant, I have checked the system for leaks and haven’t found any. Even after being parked for a few days there are no wet spots on the ground. The oil is clean with no signs of no moisture in it. I am adding about a quart of coolant a week, what is the issue.

A. The problem is most likely a leaking cylinder head gasket. The standard procedure is to pressure test the cooling system and if the system holds pressure, then the next step is to look for an internal leak. You can purchase a kit that uses a special chemical to look for exhaust gases in the cooling system. These kits are $35-$50 and are easy to use and quite accurate.

Q. My daughter has a 2007 Toyota Camry Hybrid. Lately the car has started to vibrate/slide as she brakes, as if the ABS system is engaging even though the road is clear and dry. The light with the squiggly lines will appear briefly. No other lights activate. Our mechanic has been able to experience the issue but has not been able to fix the issue. Any advice?

A. The anti-lock brake system uses sensors at each wheel that monitor wheel rotation. What you describe as a phantom ABS application can usually be traced to a rusted or cracked ABS tone wheel. A careful inspection and some testing should be able to pinpoint the problem.

Q. My Mazda 2014 CX-9 has about 55,000 miles on it. During a couple of four-hour drives on the highway I noticed a hum coming from the car. After some novice detective work figured it to be the right rear wheel bearing/hub was the problem. I removed the assembly and replaced it with a “sorry to say” economy brand part I purchased online. I road tested it and for about 300 miles of highway driving, no sounds. Unfortunately, after a few hundred more miles the same “hum” is back, although less intense. I did more internet research, and some comments were that this brand failed prematurely. And other sites mentioned a bit of a sophisticated install process. The replacement of this bearing hub is straightforward: remove defective part and install replacement. Four bolts hold the assembly to the rear axle assembly, and you just remove and reinstall the axel nut. Mixed recommendations on the torque specs for the axel nut: 200ftlbs/258ftlbs. Do you think I just got a lemon part? Did I install it incorrectly? Not like the old days when you’d repack the wheel bearings and “set” them with rotating the wheel and tightening and backing off the holding nut.

A. I suspect you may have gotten an inferior part. You are correct the replacement of the bearing is fairly simple. According to AllData the technical database I use, the attachment bolts should be tightened to 58–75-foot pounds and the axle nut is tightened to 175-202 foot pounds of torque.

Q. I have three simple questions that I can’t get an answer for so I’m coming to you. What window wash fluid do you recommend, especially in the cold Northeast states, are there any window treatment products do you recommend that shed water or prevent fogging and are gas additives worth the money? My car is a 2015 Kia Soul, but I’m sure the advice applies to most cars.

A. When choosing windshield washer fluid (which is basically soap, water and alcohol) look for fluid that will protect against freezing to at least 20 degrees below zero. Some fluids will have additives that do a better job of removing bugs and other debris and some will bead water. What ever fluid you choose, the best results come from a clean windshield. Clean the windshield inside and out with a good quality window cleaner and then go over the windshield with a clean microfiber cloth. Regarding window treatments, I have tried some and had mixed results, so I tend to stay away from them. If you are trying to prevent fogging, first make sure your defroster is set to fresh air. Fogging happens when there is a temperature differential of the inside and outside of the windshield. A DIY method to prevent fogging is to clean the window with shaving foam. I haven’t tried it on my car but it works on my bathroom mirror. Regarding fuel additives, adding a fuel injector cleaner periodically and using a gas line antifreeze just before cold winter temperatures can’t hurt, although typically not necessary if you use quality fuel and keep the fuel tak at least half full to prevent moisture.

Q. My 2008 Suzuki XL7, runs great but the RPM (idle speed) will dip or hesitate? Again, it runs great on the highway. I think it’s the timing belt or serpentine belt is off, what do you think?

A. A worn timing or serpentine won’t cause an engine to idle poorly. I suspect there is a fuel issue. This could be a clogged/dirty fuel injector, vacuum leak or even a sticking exhaust gas recirculation (EGR) valve.

Q. Let me first say that I enjoy the insight that comes from you on both your radio show and Newsday. My question is about thread sealant. When doing routine repairs on my vehicles (brakes, suspension etc.) is it advisable to use thread sealant as an additional measure of safety or is it ok to just tighten nuts and bolts according to manufacturer’s specification?

A. Topically use a thread locker (Loctite is one) when that bolt is under extreme stress or instructed to by the vehicle manufacturer. If the fasteners are something that is something that are removed periodically, I wouldn’t use thread locker, just tighten to manufactures specifications.
