TCB your PCV (PCV Valve Replacement)

Your gasoline engine goes through some exhausting work.  Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve.

Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes.  Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine. 

Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air.  That way the unburned fuel could go through the engine again and produce power. It also means the unburned fuel doesn't pollute the air.  The part that makes that happen is called the Positive Crankcase Ventilation (PCV) valve.

Besides reducing pollution and preventing the oil from turning to sludge, the PCV valve also relieves pressure in the crankcase, reducing the potential for oil to leak. One of the reasons you should get your oil changed as frequently as your vehicle's manufacturer recommends is that it helps reduce chances for problems with the PCV valve.

After a while, the PCV valve can itself get gummed up and stick, and the driver may notice oil leaks, reduced power or engine hesitation.  That's why it's important to make sure the PCV valve is operating like it should, and often it can be diagnosed during a visual inspection by our technicians.  Replacing a PCV valve is usually quick and inexpensive.  After it's done, your vehicle will run with the performance and fuel economy you're used to.  Goodbye exhaustion!

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our KPS Princeton Garage technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.

Wipe Out! New Wiper Blades for Princeton Drivers

When people in Princeton talk about vehicle safety, they think of tires and brakes. But do we think about our windshields? Isn't the ability to see a prime safety factor when it comes to driving around NJ? Yet we often don't even notice our windshields until we can't see through them or our wiper blades fail.

It's estimated that around 46 million people are driving with wipers that won't keep their windshields clear during a storm — that's 46 million people with impaired vision during a storm. For safety's sake, Princeton drivers need to change the way they think about wiper blades. Most of us, 78% in fact, only change our wiper blades after they fail. In other words, we don't get new ones until the old ones become a safety hazard. Instead, we need to make wiper blades part of our preventive maintenance routine.

Wiper blades should be changed twice a year, in the spring and in the fall. In NJ areas that experience harsh winter weather, special blades are available that prevent ice and snow from collecting on the wiper. Ask your friendly and knowledgeable service advisor at KPS Princeton Garage about wiper blades that repel ice and snow.

No matter what blades you use on your vehicle in the winter, don't expect them to clear the ice and snow from your windshield after your vehicle has been parked for a while. Using your wipers will shred your blades and may even damage your wiper motor. And don't drive on Princeton roads with a frosted windshield. That's a serious safety hazard. It can cause accidents, and you could be held liable.

Wiper blades are subjected to harsh conditions in NJ. They're out in the Princeton sun and in the cold. Over time, they become hard and brittle and lose their flexibility. Then they start to tear. Without flexibility, wipers just can't clear a windshield of water or snow. And torn wipers can actually scratch your windshield. Then the entire windshield has to be replaced — along with the wiper blades. It's a prime example of how preventive maintenance could have saved you repair bill.

Princeton drivers can purchase new wiper blades at KPS Princeton Garage or at any Princeton auto parts store. They cost about the same. But at KPS Princeton Garage we'll also throw in the installation.

Once you have good wipers installed, don't forget to top off your windshield washer fluid. If you take your vehicle in for a full-service oil change at KPS Princeton Garage in Princeton, your washer fluid will get topped off then. But it's good auto advice to purchase a jug of washer fluid to keep at home — just in case. And pack it in the car when you go on long trips.

While we're on the subject, KPS Princeton Garage advises Princeton drivers to always fill their washer fluid reservoir with windshield washer fluid. Don't ever use water. Water can freeze in the reservoir, which can damage it. It can also freeze onto your windshield. Besides, plain water just can't get a windshield clean. Think about it. Do you use plain water to clean your bathroom mirrors? And a bathroom mirror doesn't get exposed to anything near the gunk that can end up on your windshield. Windshield washer fluid was designed to do one thing — to clean windshields. Let it do its job.

A clean windshield is not just good vehicle care for Princeton drivers — it's also a safety feature. Let's keep it that way.

Keeping Your Princeton Air Fresh When Driving With a Clean Cabin Air Filter

Pop quiz: What is a cabin air filter?

A. A filter for your Princeton house?
B. A fresh, piney scent?
C. A filter for the passenger compartment of your car?

Clever you, it's C.

A cabin air filter cleans the outside air before it comes into the passenger compartment of your vehicle. It filters out common NJ air particles like dust, pollen, spores, bacteria, pollutants, exhaust gas, odors and even sparrows.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Not all Princeton vehicles have cabin air filters. They are fairly new on the scene in NJ. Last check, about 40 percent of new vehicles sold in Princeton come with cabin air filters, but the number is growing every year.

Cabin air filters make driving a lot more pleasant for people in Princeton. Your vehicle can be a haven during our NJ allergy season with very little dust and pollen getting into the cabin. Of course, like all filters, the cabin air filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your owner's manual for replacement guidelines. If your vehicle owner's manual doesn't mention your cabin air filter, ask your friendly and knowledgeable service advisor at KPS Princeton Garage for a recommendation. It's usually every year or 12,000 miles /19,000 kilometers. Change it sooner if you drive in dusty conditions around the Princeton area, or if you start to notice a funky smell coming from your vents.

The team at KPS Princeton Garage urges Princeton drivers to keep their cabin air filter cleans. It may not help with your brother-in-law in the backseat, but it will make your driving experience around Princeton more enjoyable.

Come by and we'll take a look at your cabin air filter for you.
