Battery Replacement For Your sedan

Modern cars and trucks in and around Orange run on 12 volt electrical systems. 12 volts is enough to get the job done for Orange car owners without having so much power that there is danger of electrocution. But today’s vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks, windows and sun roofs. And then us CA auto owners have all the power outlets for our cell phones, computers, and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given Orange auto owners resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your sedan. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more critical to get it replaced.

Special safety precautions are taken when working with batteries in the shop at Greg’s Orange Auto Repair in Orange, CA. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any Orange auto owners working with their battery. Be careful to not spill acid on your clothes or the sedan’s paint. Of course, avoid short circuiting the battery as well.

Replacement car batteries come in all shapes and sizes. Some cars have limited space that requires a specially shaped battery to fit. Larger engines require more powerful batteries to get them started. If you live where it gets cold in CA you will need a more powerful battery because engines are harder to start when it is cold.

Sometimes there is quite a price range in Orange auto part stores for batteries that will work in a particular car. Think of it as “good”, “better” and “best”. More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves cash in the long run for Orange car owners.

PCV Valve Service At Greg’s Orange Auto Repair In Orange

Today, we are talking about your PCV valve. The PCV Valve is a little, inexpensive part that does a vital job for Orange motorists. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the sedan engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel.

It can also cause sedan engine corrosion, something we see occasionally at Greg’s Orange Auto Repair. At high speeds on Orange freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, car makers simply installed a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the sedan’s engine.

This is much better for air quality and improves fuel economy also. (Budget-conscious Orange car owners take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets harmful gases out of the engine, but won’t let anything back in. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and decreased fuel economy.

Fortunately, it’s very easy to test the PCV Valve at Greg’s Orange Auto Repair in Orange and quick and inexpensive to replace. Even so, it’s often overlooked because many Orange motorists don’t know about it. Check your sedan owner’s manual or ask your Greg’s Orange Auto Repair service advisor. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

There’s another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That’ll need to be replaced at Greg’s Orange Auto Repair when it gets dirty.

Please ask your caring Orange service advisor about your PCV valve. For the price of a couple of burger combo meals in Orange, you can avoid some very costly engine repairs.

Emergency Items For Your sedan

Local Chino Hills roadside emergencies can range from a flat tire downtown to being stranded in a snowy ravine for three days. So you may want to consider a basic emergency kit to keep in the car at all times and a travel kit tailored to a specific trip.

Your close-to-home kit for around Orange would have some basic items to work on your car: everything you need to change a tire, gloves, a couple quarts of oil, some antifreeze and water. A can of tire inflator is a great temporary fix for minor flats. You’ll also want jumper cables or a booster box, flares, a flashlight and some basic hand tools.

Now for your comfort and safety: a first aid kit, drinkable water, high calorie food (like energy bars), blankets, toilet paper, cell phone, towel, hat and boots. Keep some change for a pay phone, emergency cash and a credit card.

People who live in areas with frequent severe weather or earthquakes may want to carry provisions for longer emergencies.

For trips away from home, consider the weather and geography as you assemble your emergency supplies. You’ll need to have a source of light and heat and will want to provide protection against the elements as well as adequate food and water for everyone in the car.

Always tell people where you are going and have a plan for checking in at waypoints. Then if you run into trouble, you can be reported missing as soon as possible and rescuers will be able to narrow the search area.

The key to safe travel is to keep your vehicle properly maintained, plan ahead, and let others know your itinerary.

Timing Belt

Ever heard the sad tale of a staggering repair bill from a broken timing belt? Bad news. Let’s take a lesson from their woes and remember to think about our timing belt.

First, let’s review what a timing belt does. The top part of the engine, over the cylinders is called the cylinder head. The head contains the valves. There’s at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves – that’s 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It’s called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything’s in sync.

The timing belt is a toothed rubber belt . But some cars use a timing chain or timing gears instead of a belt. Timing chains and gears are much more durable, but manufacturers are using belts more because they are quieter – and cheaper. If you have a small or mid-sized passenger car, crossover or mini-van, chances are you have a timing belt.

Unfortunately, timing belts fail without any warning. That shuts you down right away. A technician can inspect your timing belt and look for cracks and looseness. But getting to the belt to take a look can be almost as much work as changing it on some cars. That’s why manufacturers recommend replacing the belt from time to time. For most vehicles it’s from 60,000 to 90,000 miles or 95,000 to a 145,000 kilometers. If your owners’ manual doesn’t specify an interval ask your service advisor.

One AutoNetTV producer has had two timing belts fail. The first was while he was waiting at a stop light – that repair cost several thousand dollars. The second was while driving on the highway – that one cost more than twice as much. Both had the cars out in the shop for three weeks. His cars had what we call “interference engines”, meaning that the valves and pistons are very close to each other. If the timing belt slips even one notch, the pistons will slam into the open valves. That’s why our friend’s highway failure was so much more expensive – his engine was traveling so fast that the valves were smashed and they chewed up the cylinder head.

A non-interference engine will just shut down if the timing belt breaks. You’re stranded, but the engine doesn’t suffer permanent damage. In both cases, our hapless friend was just a couple oil changes past the recommended interval for changing the timing belt. This is one of those things that you just cannot put off. Now replacing a timing belt is not cheap – but repairs for a broken belt can be many times as much.

Check your owners’ manual right away – especially if you have more than a 60,000 miles or 95,000 kilometers. You may need to get that belt replaced right away. And on many cars, the timing belt drives the water pump. So, it may be a good idea to replace the water pump while you’re at it because 90% of the work required for the new pump is already done with the belt change. Doing both at the same time saves you a lot of money because as they say, “timing’s everything”. Parts, Timing Belt

PCV Valve Replacement

The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Gasoline engines used to simply have a hose that let the poisonous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. Diesel engines are not required to have these valves.

The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It’s really a pretty simple system, but does an important job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the engine as well. The PCV relieves pressure in the crankcase, preventing oil leaks.

Eventually, the PCV valve can get gummed up. Then it can not move enough air through the engine to keep it working efficiently. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV value problems. Your owners’ manual may give a recommendation for when the PCV valve should be replaced – usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some manufacturers don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with a visual inspection. Fortunately, PCV valve replacement is both quick and inexpensive. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Orange service technician tells you its time to replace your PCV valve, you will know what he’s talking about. If you have had your car for a while and this is the first you’ve ever heard of a PCV value, ask your tech to check yours out or call Greg’s Orange Auto Repair at 714.633.8219.
