Your alternator makes electricity to start and run your engine and all of the vital electrical systems in your vehicle. That’s everything from the on-board computers to the turn signals. And of course there is the entertainment system, seat heaters, power windows and everything you plug into the power outlets. After your alternator makes enough electricity to do all that, it recharges your battery with what’s left over.When TRUCKEE drivers constantly have a low or dead battery, the alternator is usually a prime suspect. However, the alternator is just one vital component of the starting/charging system, and a problem with any of the other components could be the actual cause.In addition to the alternator, the charging/starting system includes the battery, starter, serpentine belt system and all of the electrical cables that connect them.

Today's The Auto & Tire Doctor Inc article focuses on severe service maintenance. Many TRUCKEE drivers are not aware of them and yet there are also very vocal advocates in CA who think that severe service schedules apply to everyone. Somewhere between a complete lack of awareness and the dire blanket statements lies a reasonable approach to severe service maintenance at The Auto & Tire Doctor Inc.To back up a little, vehicle owner's manuals have schedules for preventive maintenance: things like oil changes, transmission service and so on. They say you should change your oil after a certain distanced traveled or after so many months. TRUCKEE drivers understand this very well. What they may not know is that there are actually two service schedules: the regular schedule and the severe service schedule. The mileage and time intervals are lower on the severe service schedule.Now when you hear 'severe service,' you may think it doesn't apply to you bec ... read more

Most TRUCKEE drivers worry about a breakdown or a tire blowout on a busy CA highway, but don't worry too much about failure of their air conditioning system. A breakdown on the side of the road can be a miserable and dangerous affair during TRUCKEE rush hour, but so can a long ride in a hot vehicle.A lot of TRUCKEE drivers judge their vehicles' air conditioning systems as “non-essential” and so may neglect them in favor of repairs and maintenance that keep the vehicle running. But preventive maintenance of an air conditioning system is simple and inexpensive, while auto a/c repair can be very expensive.TRUCKEE drivers should have the refrigerant in their air conditioning system checked regularly to ensure it is adequate and clean. Air conditioning systems often fail because air and water have contaminated the refrigerant. Air reduces the efficiency of the refrigerant ... read more

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for TRUCKEE drivers to prevent. The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again. The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage. Different engines require different types of coolant/antifreeze. The owner's ... read more

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at The Auto & Tire Doctor Inc. At high speeds on CA freeways, the pressure can build up to the point that gaskets and seals start to leak. Back in the old days, vehicles were simply installed with 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 vehicle's engine.This is much better for ai ... read more
