Modern cars and trucks in and around San Ramon 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 t ... read more

Local Pleasanton 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 Pleasanton 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 ... read more

California new car dealerships are happy to leave you with the impression that you should have all of your scheduled automotive maintenance performed at the dealership during the warranty period. Some go so far as to imply that your warranty protection depends on it. In fact, nothing is further from the truth. Federal laws in both the United States and Canada specify that you do not have to have your vehicle serviced at a dealership to maintain warranty protection. The laws further state that a vehicle manufacturer cannot mandate that you use their particular brand of replacement parts or fluids. This certainly means you have many more service options, but what about quality? First off, it is important to know that vehicle manufacturers do not make all of their own parts. They look to thousands of independent suppliers to manufacture the parts that go into your car or truck. Many of these same manufacturers that make the parts that are original equipm ... read more

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 ... read more
