Fuel Filter Replacement

Hello Princeton resident! You would never like to drink a glass of mud, right? Well, your vehicle feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your vehicle will still run. But, then the contaminated fuel can clog your fuel injectors and allow particles into your engine.

A vehicle with a partially clogged fuel filter might run well around Princeton, but sputter and strain on the because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive in NJ and the gas you buy. If you drive a lot on dirt or gravel roads in rural NJ, your fuel filter will have a harder time keeping the fuel clean.

And, we hate to say it, but buying the cheapest gas from bargain stations sometimes means dirtier fuel that'll clog the filter sooner. Major brands tend to be cleaner and certainly have higher levels of detergent additives.

Of course, manufacturers recommend intervals for changing the fuel filter. But, it's a little more complicated than that for Princeton residents. Some manufacturers stopped listing recommended intervals for fuel filter replacement or have very long intervals like every five years or 80,000 miles (130,000 kilometers). So you may need to look to other sources for recommendations. Vehicles older than six or seven years are especially at risk because they have had time for dirt and rust to build up in the fuel tank. A clean fuel filter keeps the gas flowing. Even a partially clogged filter puts added strain on the vehicle fuel pump. That can shorten its life and result in repair.

As is often the case, spending a little money now on something as inexpensive as a fuel filter can save money for Princeton residents down the road by improving and preventing repairs. At KPS Princeton Garage in Princeton, we can check your fuel filter. It is better than fixing a burned-out vehicle fuel pump or ruined fuel injectors.

It Wears on You (Tire Rotation)

If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires.  But you have to do it regularly.

A lot of drivers think skipping tire rotation is a way to save money.  But when you don't rotate your tires, they will almost certainly wear unevenly.  That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off.  And that process isn't exactly the same on each corner of your vehicle.  Some vehicles have the drive wheels in the front, some in the rear and some on all wheels.

Rotating your tires at regular intervals minimizes the differences in the way the tires wear.  The amount and pattern will be spread out equally if your tires spend time at all different positions.  The more even the wear, the more consistent traction, handling and braking will be.  All four tires will last longer this way, and when it is time to replace your tires, they'll all be worn out the same so you can replace all four with the same model tire.

Some people who choose not to rotate their tires find that one or two will wear much faster than the others, and often they'll replace just the worn ones.  While you can find similar tires, they won't all be the same and will certainly not have the same amount of wear. 

There are different tire rotation patterns depending on several factors: front-wheel drive, rear-wheel drive, all-wheel drive, directional tires/wheels, different sized wheels/tires on front and rear axles.  Also keep in mind that when your tires are new, some tire manufacturers require you to rotate them or else they won't honor the warranty. 

Your manufacturer recommends intervals for tire rotation, so it's best to follow their suggestion.  Your vehicle service facility can advise you when you need to get your tires rotated.  And many facilities include free tire rotation for as long as they're on your vehicle if you buy your tires at their shop.

Not-So-Common Sense (Sensor Failures)

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works.

You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. 

Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly.

Here's an example of a sensor doing its job.  Your engine needs oil to lubricate metal components so the friction doesn't damage them.  Your engine has an oil pressure sensor that tells a computer called the Electronic Control Unit (ECU) if things are good to go or if there's something wrong, maybe the oil pressure is too low to keep things lubricated.  If it is, it gives a signal for the vehicle not to start, protecting the engine. 

Of course, the sensors can go bad, too, with some of the same results.  And so someone has to figure out if it's the sensor that's failed or if it really has detected a problem.  That is the challenge for technicians with specialized equipment to decipher the signs.  If a bad sensor is found, it may need to be replaced.  Sometimes a thorough cleaning can do the trick.  In either case, your service facility can track down the problem and get you back on the road.  Makes sense, doesn't it?

Fall and Spring Inspection at KPS Princeton Garage

Good vehicle care for us Princeton residents has always meant taking our vehicles in every spring and fall for a check-up. Vehicles needed routine maintenance to prepare them for the changes in weather. Today's vehicles aren't quite as sensitive to seasonal changes. Older vehicles required different weights of oil for summer and winter. But today's engines can run on the same oil all year. Both the engines and the oils have been improved.

Antifreeze—or coolant as it's also called—protects the engine from both freezing and hot temperatures and thus is required by the engine year-round. Modern coolants don't have to be changed as often as they did in the past, but your owner's manual has a recommendation for when it should be replaced to extend cooling system life.

Getting a spring and fall checkup at KPS Princeton Garage in Princeton for your vehicle is still good auto advice.

First of all, there is a lot of preventive auto maintenance involved in properly caring for a vehicle. Dropping your vehicle off twice a year at KPS Princeton Garage for a quick inspection and routine maintenance is still part of good vehicle care. The changes in the NJ seasons can provide a good reminder that it's time to get the vehicle serviced, just as they remind us that it's time to take care of the furnace or air conditioner, purchase school clothes or bathing suits, drag out or put away the coats and boots.

There are other advantages to spring and fall maintenance for Princeton residents. Springtime signals the advent of warmer weather. Although modern coolant is designed to last longer than one season, it's a good idea to check it regularly to ensure you have enough. While you're at it, your vehicle should also be checked for leaks and worn hoses in the cooling system.

Summer is the time when most of us Princeton residents take vacations or go on road trips. So a spring check-up for our vehicles can lead to a stress-free summer and better memories on the road.

Fall, of course, signals the advent of colder weather in the Princeton area. This is a good time for a routine battery check. The hot weather of summer takes a toll on battery life – then comes winter. Cranking up a cold engine takes a lot more battery power than starting a warm one. So before that cold weather hits, it's a good idea to check your battery and replace it if necessary. But your tires aren't completely adapted to changing weather conditions. If you live where temperatures drop below 45°F (7°C) in the winter, or if your commute frequently takes you through snow or ice, you may want to consider changing to winter tires in the fall.

A fall check-up at KPS Princeton Garage, just like a spring check-up, can keep you on the road no matter what NJ weather brings. Consider how much a worry-free summer vacation and a less stressful Princeton winter commute are worth to you. Then, spring and fall, reset your clocks, change the batteries in your smoke detectors and take your vehicle in for a check-up.
