Oh, Stop! (Disc Brake Service)

Every time you drive your vehicle, you wear down your brakes just a little bit.  And after a while, that adds up.  Gradually, your stopping power isn't like it used to be.  Since brakes are one of your vehicle's most important safety features, it just makes sense to keep them performing well.

Most vehicles have disc brakes.  One key component, as the name suggests, is the disc.  Most vehicles have discs on their front and rear wheels.  The discs (also called rotors) are made of metal, and each rotates with the wheel hub.  Your brakes also have pads that make contact with the rotors when you press down on the brake pedal, and the friction stops your vehicle.

After many, many stops, that friction wears down both the pads and the discs and reduces their ability to stop the way you need them to.  The discs may also become uneven from all the heat they generate, and your brakes won't stop as well as they used to when they were newer. 

Some signs that your rotors need attention include vibration at the wheels when you stop, discolored rotors (the metal looks blue), excessively hot rotors, or grooves in the metal.  If you see any of these signs, it's time to bring in your vehicle for us to inspect your brakes. 

A technician will measure the thickness and trueness of the rotors and check the surfaces for wear.  If they need to be replaced, they'll be done in pairs, so if a front rotor is bad, the other front rotor will also be replaced. Usually, your brake pads will be replaced at the same time.  You can ask your service advisor if higher-performance brakes would benefit you.

When your vehicle is at the shop, the technician will check other components of your brake system to make sure they are operating safely. Brakes are vital to the safe operation of your vehicle.  Keep them well maintained so they can be there when you need them.

Positive Crankcase Ventilation ? PCV Valve Service at Union Street Automotive

Hello Newark! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in NY vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.

The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at Union Street Automotive in Newark, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Newark driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual.  So if you're looking for auto advice about the PCV valve, you may have to ask our pros at Union Street Automotive.

Taking care of our PCV valve protects the environment in NY and improves vehicle performance. It's just part of good vehicle care for Newark drivers and a way all of us can do our part to improve the world we live in.

The ?Man-Made? Engine Oil (Synthetic Oil Change)

If you own a newer vehicle, your vehicle’s manufacturer may require that it use synthetic oil instead of conventional oil.  Synthetic oils are more stable, don’t break down as easily, and provide better engine protection than conventional oil. All those things can prolong the life of your engine and help it run better.

Imagine the damage that could happen to your engine as it operates at high speeds and very hot temperatures.  Oil reduces the friction between the metal parts.  That’s why it’s important that it maintains its lubricating properties for a long time, which synthetic oil does better than conventional oil.  

Clean oil is better than dirty oil because it has fewer impurities.  Synthetic oil is purer because of how it’s formulated and manufactured.  Plus, as the outside temperatures change, the ability of oil to operate in those conditions is important.  
For example, the colder it gets, it’s important for oil to flow easily to retain its lubricating properties. How thick a fluid is changes in different temperatures, and that thickness is known as viscosity, Synthetic oils are better at maintaining their viscosity throughout temperature changes. 

It’s not only newer vehicles that can benefit from synthetic oil.  If you have an older vehicle, synthetic oil may offer superior lubricating than conventional.  Our technicians can advise you what’s the best oil for your vehicle and how often you need to change it, which may vary from the owner’s manual recommendations.  You might find you’re able to change your oil less frequently than you used to with conventional oil.  

Yes, synthetic oil is more expensive than conventional, so let us help you decide whether its advantages are worth the difference in price.

Lubricate Driveshaft

See if any of these are happening to your vehicle.  You feel it vibrating excessively underneath when it’s running, or you hear strange clunking, grating, or grinding sounds coming from beneath.  Maybe it’s hard to turn your vehicle, or you can hear squeaking when you’re going slow.  Perhaps you feel a shudder when you step on the throttle.  

Any of those could be signs that your vehicle’s driveshaft might need lubricating, and it’s important to have one of our technicians check it out. Your vehicle’s engine puts out a lot of twisting power.  That force is called torque, and the driveshaft is the part that handles the job of transferring all that torque from your engine to the wheels.  If it’s a four-wheel or all-wheel drive vehicle, it will have driveshafts front and rear. 

Some driveshafts have different segments which are connected by couplings called U-Joints.   So that everything can glide along fine, that whole assembly needs to stay well lubricated.  Our technician can inspect the driveshaft and U-joints to make sure there aren’t any broken or excessively worn parts.  

Many manufacturers recommend servicing and lubricating the driveshaft at certain intervals, and it’s important to keep on that schedule.  It’s essential because poor lubrication can lead to a failure while you are driving, possibly causing other expensive parts to fail.  Not keeping your driveshaft lubricated or failing to maintain it regularly is the top cause of driveshaft problems.

Positive and Negative (Battery Care)

You notice when your smartphone's battery starts to go weak on you.  It runs out of juice faster than it did when it was new.  Bet you pay attention to that pretty closely.

Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather.  (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.)

 The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity.  A vehicle battery discharges electricity and then needs to be recharged.  Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine.  It's a pretty cool system that's been around for a while.  An alternator changes the mechanical energy into electricity that then charges the battery.  And your vehicle is designed to charge it just the right amount with a voltage regulator. If your battery constantly gets too much voltage, it could stop holding a charge. 

Another way a vehicle battery loses its ability to hold a charge is when it gets hot.  In warmer weather, some fluids in your battery evaporate which can damage some of its internal components.  Then, you've got a dead battery.

Back to your smartphone for a second, it probably has a little indicator or maybe an app that shows you how healthy it is or how much charge it's holding.  Well, your service repair facility has equipment that can test your vehicle's battery for the same things.  If that test shows you need a new battery, then it's probably time to replace it.

A technician can also check to see your battery is being charged at the correct rate.  If you have a battery that is not sealed, a technician can check to see it needs more water added to it.  The technician will also make sure dirt or other contaminants aren't acting as electrical conductors and discharging the battery.  Plus, your battery's terminals may need cleaning.

Most people just forget about their vehicle's battery until there's a big problem with it. Here's one rule of thumb: expect a battery's life to be about 5 years. Just like you wouldn't want your smartphone to leave you without any way to make phone calls or send texts, you wouldn't want your vehicle to leave you stranded with no way to start it, would you?   

When it comes time to make that new battery choice, your service advisor can offer you some good options, taking into account the climate you drive in, what you use your vehicle for and what your budget is.  Hey, your smartphone's battery is all charged up.  How about calling your service advisor for an appointment right now?
