Today, we are talking about your PCV valve. The PCV Valve is a little, inexpensive part that does a critical job for Marietta drivers. PCV stands for Positive Crankcase Ventilation.
The crankcase is the bottom area of the engine that holds the oil. When the suv 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.This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause suv engine corrosion, something we see occasionally at Aero Automotive. At high speeds on Marietta freeways, the pressure can build up to the point that gaskets and seals start to leak.
Back in the old days, auto manufacturers 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 suv’s engine.
This is much better for air quality and improves MPG also. (Budget-conscious Marietta car owners take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets detrimental 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 gas mileage.
Fortunately, it’s very easy to test the PCV Valve at Aero Automotive in Marietta and quick and inexpensive to replace. Even so, it’s often overlooked because many Marietta auto owners don’t know about it. Check your suv owner’s manual or ask your Aero Automotive 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 Aero Automotive when it gets dirty.
Please ask your honest Marietta service advisor about your PCV valve. For the price of a couple of burger combo meals in Marietta, you can avoid some very costly engine repairs.
Hello Marietta drivers, let’s talk about your often-unnoticed but extremely vital PCV valve. 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. Atlanta folks know that 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.
Pre-1963, gasoline engines had a hose that let the detrimental 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. (Can you imagine how polluted our Atlanta air would be if every car had been releasing those poisonous fumes for the last fifty years?) 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 it does the 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 detrimentaloil leaks.
Eventually, the PCV valve can get gummed up. Then it can’t move enough air through the engine to keep it working properly for Marietta motorists. 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 valve problems. Your car maker’s 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 car makers don’t list a recommendation in the manual, so it can be easy to overlook.
Many PCV system problems can be diagnosed with an automotive analysis by your honest Aero Automotive service advisor. Fortunately, PCV valve replacement is both quick and inexpensive at Aero Automotive. 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 Marietta 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 service advisor to check yours out or call Aero Automotive at 770-926-9050.
Modern cars and trucks in and around Marietta run on 12 volt electrical systems. 12 volts is enough to get the job done 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 we 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 us 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 car. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak and need to be replaced.
Special safety precautions are taken when working with batteries in the shop at Aero Automotive in Marietta GEORGIA. 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. Be careful to not spill acid on your clothes or the vehicle’s paint. Of course, avoid short circuiting the battery as well.
Replacement 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 in a cold climate you will need a more powerful battery because engines are harder to start when it is cold.
Sometimes there is quite a price range 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 money in the long run.
Local Atlanta 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 Marietta 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.
An overheating engine is not a happy engine! If your radiator is faulty, you need to take your car to an auto repair technician before the problem causes further damage to your car. A faulty radiator can lead to sever problems, or even seize your engine.
The radiator is responsible for keeping your engine cool. If you engine overheats, it causes damage to your engine’s components or even a complete engine breakdown. Repairs to your engine can cost a fortune, while a seized engine needs to be replaced, costing hundreds of dollars.
All of these problems can be avoided if you have your faulty radiator repaired by an auto repair technician.
Diagnosing a faulty radiator
Faulty radiators are fairly easy to diagnose because your engine will be overheating if your radiator is not functioning properly. Some of the causes of faulty radiators include obstructions, leaks or broken fans.
If there is an obstruction preventing hot fluid from flowing through your radiator, where it is cooled, it will cause the engine to overheat. Clearing obstructions is fairly simple and these obstructions can cause further damage to your engine, so you should have them cleared straight away.
Radiator leaks are incredibly common. If there is a leak in your radiator, the radiator fluid will flow out, and the radiator will no longer cool the engine fluid. Once the leak has been located, it can be plugged to fix the problem.
If there are no leaks or obstructions, you may need to replace the radiator fan. The fa is an important part of your car’s cooling system and when it fails, it can cause overheating and engine damage.
Aero Automotive is a NAPA certified auto center with more than 10 years experience in the auto repairs industry. Contact us today and one of our highly qualified auto repair technicians will examine and fix your faulty radiator before any further damage is caused to your engine.
Like everything automotive, there have been great strides in headlight technology in recent years. We can all drive more safely at night because of it. Good headlights improve visibility down the road, enabling you to see farther. They also improve your peripheral vision, helping you to see the sides more clearly. The more you can see, the quicker you can react to road conditions. This is important because nearly half of traffic fatalities take place at night. And as the country’s population ages, everything that helps older eyes is welcome.
Most new cars come with halogen headlamps. A decade ago, halogens were exotic and expensive. Now that they are standard equipment, the price has come way down. Many luxury cars are equipped with high intensity discharge, or HID, headlamps. You have probably seen them on the road, they’re very bright and have a bluish tint.
From behind the wheel, there is no doubt that HID headlamps are the best thing going. However, many people complain about HID lights in on coming traffic or when they approach from behind. In fact, when the National Highway Traffic Safety Administration called for public comment, they received a record number of complaints about HIDs. This has lead to several studies – your tax dollars at work. Some expect future regulation of HID lamps.
All halogen headlamps dim over time. Experts recommend that they be changed out once a year. AutoNetTV suggests you replace your headlamps in the fall at the end of Daylight Savings Time. It’s easy to remember – when you change your clock, change your headlamps. Remember to replace all headlamps at the same time – then all your lights will be equally bright. You will appreciate it during those long winter nights.
If you have an older car with old style headlamps – they make halogen replacement lamps for most cars. You’ll be amazed at the difference this upgrade will make.
In addition to regular halogen lamps, you can upgrade to premium lamps that filter some of the yellow light, making a bright white light that’s more like natural sunlight. This light’s easier on the eyes and should improve reaction time.
Now, you may be able to step up to HID headlamps, depending on the kind of car you drive. These lamps should last the life of your car, but cost several hundred dollars a pair. If you want other drivers to think you’re running HID lamps, you can even buy regular halogens that have a bluish tint. Does she or doesn’t she? Only her GEORGIA automotive service technician knows for sure.
Over time, plastic headlight covers can get cloudy or yellowed. In fact, AAA reports that nine out of ten headlights are dirty or yellowed, greatly reducing vision. In addition to helping you replace your headlamps, many service centers such as Aero Automotive in Marietta, GEORGIA can restore your headlight covers. Headlights can be restored at a fraction of the cost of replacing.
