PREVENTIVE MAINTENANCE AND WHY
Oil changed every 3,000 - 4,000 milesdepending on driving habit. Use good premium motor oil most vehicles use
5w30, 5w20 or 10w30. If you want to make your engine last longer and save fuel, when you change your oil have us put in Mobil 1 synthetic oil; you can then change your oil every 6 months or 6,000 - 7,000 miles. Ask us and we can explain the benefits of the best oil made Mobil 1 synthetic.
Drain and fill cooling system every 2 yr. or 30,000 miles whichever comes first. Reason: Antifreeze turns to acid base as it breaks down, which produces an electrical charge in. the cooling system. This eats away at the aluminum surfaces of the intake manifold or cylinder head. This in turn gives you premature head gasket and intake gaskets failure. It also can clog radiator and heater core.
Replace fuel filters every 30,000 miles. Clogged fuel filters can prematurely burn out fuel pumps. Price varies per vehicle on fuel pumps, but run from $100.00 to 400.00 plus labor. At that price it is easy to see why replacing fuel filter is important. Also note; try not to run fuel under 1/4 of a tank. Most pumps are in the gas tank and run cooler with fuel above 1/4 tank. This also helps to extend the life of you fuel pump. This also helps keep the screens in the injectors clean. Make sure you always use a Branded high quality detergent gasoline.
Transmission services every 30,000 - 35,000 miles for automatics. Standard transmission every 30,000 to 40,000 should be drained and filled. Reason: Transmission fluid also breaks down and turns to an acid base, which eats away and hardens the rubber seals and o-rings in the transmission and valve body. When these o-rings get hard, especially in cold mornings, you lose fluid pressure to the clutches, which tend to slip and burn. This causes premature transmission burn out. By keeping the fluid clean most transmissions can go 200,000 miles or more. Most transmissions hold 12 to 14 quarts of fluid. When you do a service you only get 4 to 6 quarts out of the transmission pan. This is why at 60,000 we flush 14 quarts through the system, to get all the fluid out o the transmission. This helps keep clutches from chattering and slipping and also keeps seals pliable.
Engine Tune up at 30,00 - 60,000.Don't be mislead by the 49.95 tune up specials: Most vehicles do not need spark plugs until 30,000 to 60,000 miles depending on the type of plugs used from the factory. At 30,000 we perform a throttle body cleaning, check plugs and replace if needed, replace pcv valve and air filter also if needed. Check computer system for codes, check belts. We also check timing if applicable. Check idle specs and replace fuel filter. Inspect distributor cap and rotor is equipped. Check ignition wires. We also test your oxygen sensor (O2 sensor) performance. We test these with a lab scope. I recommend at 60,000 to replace O2 sensor anyway. They may still work but they switch way to slow around this mileage. Most 02's get slow and this effects fuel economy. This will also help keep your catalytic converter from overheating and burning up prematurely. The 02 sensor is a sensor that the computer uses to adjust fuel trim. (For lower emissions and fuel economy)
Flush brake fluid every 30,000 miles. Especially if equipped with antilock brakes. Some ABS units are over $1500.00. One of the reasons they go bad is brake fluid absorbs water which deteriorates the electric solenoids in the ABS system along with wheel cylinders and calipers. When brake fluid gets hot the water in the system boils and creates an air pocket which gives you a low brake pedal and reduced braking.
Power steering flush system every 30,000 miles. If you want your steering rack to last longer, especially GM vehicles. This will help keep the power steering pump and steering rack in good shape. These also have rubber o-rings just like transmissions. Approx. cost of steering rack for rebuilt unit is $150.00 and more plus labor of up to 4 hours, depending on the vehicle. Also an alignment needs to be performed when done.
Drain & fill differentials every 30,000 - 40,000 miles and transfer case of 4 wheel drives. This will help eliminate condensation and get rid of metal particles floating in the oil that ruins the bearings and seals.
Repack wheel bearings, where applicable every 30,000 to 40,000 depending on vehicle. Adjust rear brakes and clean the linings. Rear drum brakes should last between 50,000 and 80,000 miles if adjusted properly. Proper adjustment in the rear brakes can make the front disc brakes last longer also.
Also at 60,000 I would recommend high pressure fuel injection cleaning. Top cylinder carbon cleaning and throttle body cleaning. Remove and test EGR valve (exhaust gas recirculation valve) and clean carbon from passageway and valve. This helps eliminate engine ping or knock, improves fuel mileage substantially and helps eliminate a lean running engine, which can cause severe damage and also can improve power and performance of an engine.
60,000 miles we suggest (especially GM cars) replace ignition wires due to high resistance which burn out ignition coils. (Cost of coils around 58.00 each x 3 in a 6 cylinder car plus labor)
60,000 flush cooling system and replace thermostat. Reason: Thermostats can go bad with no tell tale sign. Sometimes they stick open or open too soon. The computer looks at engine temperature. If the temperature is to low the computer will keep the engine running richer than it should. The computer thinks the engine is still cold. This dilutes oil and carbons engine and add to the clogging of the catalytic converter all prematurely. It also effects automatic transmission. The transmission has a lockup clutch that won't engage if engine temperature is less than 170 degrees for most vehicles. Also some overdrives won't shift into 4th gear. The other reason is that the thermostat doesn't open you overheat. Which when you realize it, it may be too late. I think it's a very cheap insurance policy to replace the thermostat & gasket.
