Cooling System Service at D AND E AUTO REPAIR in CHICO

CHICO drivers often ask questions about the cooling system, the system that cools your vehicle engine and keeps it at the proper operating temperature. Let's examine the topic in two areas: first, the coolant itself and second, the parts that make up the cooling system. The coolant is the mix of water and antifreeze that circulates through the engine to draw off heat. First, you need to have the proper amount. If you don't have enough coolant, it can't keep your vehicle engine cool. You also need the right kind of coolant. Different makes of vehicles require different coolant formulation to protect against corrosion. Finally, your coolant needs to be fresh. Over time and miles of driving, the anti-corrosion additives in the coolant are depleted, and the coolant can actually start to eat away at the vehicle's cooling system parts. Your owner's manual and your D AND E AUTO REPAIR service advisor can help you with the reco ... read more

D AND E AUTO REPAIR Automotive Tips: Axles

The axle assemblies in your vehicle transfer power out to the drive wheels.  On a rear-wheel drive vehicle, there is an axle shaft that goes from the differential in the center of the axle to each rear wheel.  On a front-wheel drive vehicle, the axle shafts go from the transmission to each front-wheel.  All-wheel drive vehicles have axle shafts connected to all four wheels.  Axles assemblies are tough parts: they transfer torque from the engine to the wheels to move the vehicle.  Tough as they are, they are still subject to normal wear and tear.  The axle shafts are in a sealed housing with lubricant that protects the axle shaft.  When there is a leak anywhere in the axle assembly, lubricant gets out and dirt, water, and other contaminates can get in.  This can greatly accelerate axle wear.  If an axle assembly fails, you're not going anywhere. A worn or damaged axle assembly on the front will make a clunking sound during low speed tur ... read more

The Harm in Skipping an Oil Change

Some new vehicle manufacturers are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles or more.  Following these recommendations is very important to avoid engine damage.  When you go too long between oil changes, oil starts to turn to sludge.  This causes small oil passages to clog and engine parts to fail. What causes oil sludge? It's a factor of time and mileage.  There are hot spots in every engine that cause oil burn off that leads to sludge.  Also, water from normal condensation can build up in the oil.  This water also creates sludge.  Severe driving conditions lead to more rapid sludge formation. Severe driving includes short trips under four miles or trips under ten miles in freezing conditions.  The engine just doesn't get warm enough for the water in the oil to evaporate. Severe conditions are at the heart of the problem.  Stop and go driving, towing, dusty condi ... read more

Fuel Injector Cleaning In CHICO

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. High temperatures under your hood and variations in CHICO gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. When your vehicle's injectors are dirty, the fuel doesn't burn as efficiently, resulting in poor fuel economy and loss of power. So it's important to keep your fuel injectors clean. We can perform a full fuel system service for you at D AND E AUTO REPAIR in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.
