Cooling System Components

Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Princeton auto owners don't give much thought to until it fails and then they're stranded by the side of a road in NJ.

Cooling systems fail more often than any other mechanical system – usually because of neglect. Don't you hate it when something breaks and you could have done something to prevent it?

The good news is that if Princeton drivers take care of their cooling systems, they can keep working for the life of their car.

Here at KPS Princeton Garage in Princeton, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

It sounds complicated, but we Princeton residents don't have to be experts – we can leave that to our friendly and knowledgeable service advisor at KPS Princeton Garage. But, having an overview will help us remember how to take care of your car's cooling system.

Most Princeton folks would be surprised to know that burning fuel in your engine produces up to 4,500 degrees F/2,500 degrees C of heat. And all that heat has to be dealt with. If the heat can't be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.

Now the water pump is what forces the coolant through passages in the vehicle engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some cash on replacing the belts and water pump is much less than the cost of repairing the extremely massive damage that can be done when an engine seizes.

There's another little known but important part of the coolant system that protects the engine. It's called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.

It is hard to believe, but the expanding frozen coolant is enough to actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.

The team at KPS Princeton Garage can check your cooling system and make any necessary adjustments or repairs. Give us a call.

When You Hear the Crash in Princeton: What to Do After an Accident

Motorists in North America drive about 3 trillion miles/4.8 trillion kilometers every year. There are over 250+ million licensed drivers, and approximately 6.2 million accidents happen every year. Unfortunately, if we're going to drive vehicles, there are going to be accidents. Knowing what to do in case of an accident can help reduce the stress and cost of the situation. It can also protect you from false claims, incorrect judgments and unjust liabilities.

Never leave the scene of an accident. This is a crime, even if the accident is not your fault. If you leave the scene, it is referred to as a “hit-and-run,” and the fines are steep in NJ. You can even lose your driver's license or spend some time in jail. If someone has been injured in the accident, most laws require you to help them. You must call for help. If you can, you must also render first aid.

Call 9-1-1 or get someone else to call 9-1-1 as soon as possible. Tell the operator if there are injuries or any circumstances that require fire services, such as leaking gas, broken utility lines or, of course, flames. Put out flares, turn on your flashers or lift your hood to warn other Princeton motorists that there's been an accident.

File a police report. This can seem like a hassle when there are no injuries and only minor damage to vehicles. But you'd be surprised at the lawsuits and false claims that can arise from fender benders. You want a police report to protect yourself.

Don't talk about the accident with anyone except the police. After an accident, adrenaline is pumping and emotions are running high, and our first reaction is often to relive and recount our experience. Don't. Again, people can and will use your words against you, and in a highly emotional state, you may not say exactly what you mean. Entire court cases have hinged on the meaning of one misplaced word. Talk to the police. Don't admit guilt or fault, not to the police or to anyone else. People often feel guilt after an accident, but later, when details are analyzed, it turns out not to be their fault. Don't say, “I'm sorry,” but rather, “Can I help? What can I do?” Sympathy has often been misconstrued as an admission of fault. On paper, your words will sound more sterile than at the accident, and they can be used against you.

Collect contact information from everyone involved in the accident. Get the officer's name and badge number. Get the other driver's name, address, phone number, date of birth, driver's license number and expiration and insurance information. Get a description of the other vehicle as well as its license plate number and vehicle identification number (VIN). Most insurance companies don't keep records of license plate numbers, so the VIN is the best identifier you have of another vehicle.

This is going to be too much to remember once you're in an accident. So write down or make a note on your phone with the information you need.

Ask witnesses to wait for the police to arrive. If they can't, then get their contact information. Ask them to jot down what they saw. If witnesses refuse to give you their names, write down their license plate numbers. That way the police can find them if necessary.

After the accident, call your insurance company. Also, if you have or think you might have an injury that did not require immediate care at the accident, contact your physician right away.

There's a lot Princeton drivers can do to prevent accidents. Defensive driving. Good car care and preventive maintenance. But if an accident does happen in the Princeton area, we should be prepared to handle it well. It will ease the stress of the situation and protect us from potential legal and financial harm. Be prepared. It's good auto advice in every situation. Ask our pros at KPS Princeton Garage for more safe driving tips the next time you visit.

The Engine Gets a Boost (Turbocharged Engine Maintenance)

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower.

The technology to do just that has been around for a long time. It's called a turbocharger.

Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops.

Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional gasoline engine. The general rule of thumb is: the fewer the cylinders, the better the fuel economy.

A turbocharged vehicle uses a turbine that is turned by exhaust gas. That compresses air that goes into the engine, which then allows it to use more fuel per second, increasing power. One advantage of a turbo is that it is only engaged when the driver demands more power from the engine by stepping on the throttle harder.

One thing to remember, though, is that turbocharged engines have additional parts and are more complex. That means they can be more expensive to maintain. The upside? You'll likely save fuel.

Like any complex machine, it's important that you maintain your turbo vehicle so it will give you more years of service. KPS Princeton Garage technicians are trained to inspect and service the systems associated with a turbo engine. If you already drive a turbocharged vehicle, keep up your regular maintenance schedule to get the longest life and performance out of it.

Because of the advantages these powertrains offer, turbo engines are definitely here to stay.

Hold the Oil! (Oil Pan Gasket Replacement)

You've likely heard how important oil is to your vehicle's engine. Did you know that there's one part that's responsible for holding that oil so you can use it every day? It's called the oil pan, and it sits at the bottom of the engine.

The oil pan is a vital, though simple, part of your engine's lubrication system. Oil circulates through parts of your engine to keep them lubricated. It reduces friction so everything works smoothly. Without oil, friction would quickly destroy your engine. The oil pan keeps that oil contained in the lubrication system, so it's important that the oil doesn't leak out. Since it's a metal part attached to another metal part, there is a gasket between the oil pan and the part of the engine it attaches to.

Various things can put stress on the oil pan and gasket, including weather extremes, the speed you're traveling and the condition of the oil. You may drive over a couple of bad roads and kick up debris onto your oil pan. All this wear and tear, heat and time can take their toll. So after a while, the gasket can just wear out and start leaking. It usually starts pretty slowly. If you see oil visible under your vehicle where you park it, that might be a sign of a leaky oil pan gasket. Another sign? You smell burning oil coming from your engine. If the leak is bad and your engine has lost a lot of oil, you may eventually see the oil light go on.

Let your service advisor know if you are experiencing any of these things. Driving with insufficient oil can badly damage your engine. And it can do it quickly. A KPS Princeton Garage trained technician will check to find the source of the leak. It may just be a gasket, but it also could be the oil pan is damaged and needs replacing as well.

This is a repair you should get taken care of. Your engine needs its lubrication system intact to provide you many years of service.
