Automotive Check Advice by Certified ASE Technicians

Car Maintenance Intervals and Specific Information

System	Monthly	Bi-Monthly	6 Months	Information
Air Filter			Check	Check the air filter every other month. Replace it when it's dirty or as part of a tune-up. It is easy to reach, in a rectangular box at the forward end of the air duct hose assembly.
Antifreeze	Check			Check the antifreeze/coolant level weekly. Some cars have transparent reservoirs with level markings. Fill to level marking with 50/50 solution of antifreeze and water. Caution: Do not remove the pressure cap when engine is hot.
Battery		Check		Use extreme caution when handling a battery since it can produce explosive gases. Do not smoke, create a spark or light a match near a battery and always wear protective glasses and gloves. Have it checked with every oil change. Cables should be attached securely and be free of corrosion. If battery has filler holes, add only clear odorless drinking water.
Belts		Check		Inspect belts and hoses monthly. Replace worn, glazed or frayed belts. Tighten them when more than 1/2" of slack can be depressed between the pulleys. Vehicles with spring loaded belt tensioner require no adjustment. Replace bulging, rotten or brittle hoses and tighten clamps. If a hose looks bad, or feels too soft or too hard, it should be replaced.
Brake Fluid		Check		Check brake fluid monthly. First, wipe dirt from the brake master cylinder reservoir lid. Pry off the retainer clip and remove the lid or unscrew plastic lid, depending on which type your vehicle has. If you need fluid, add the approved type and check for possible leaks throughout the system. Fill to mark on reservoir. Caution: Do Not Overfill.
Engine Oil		Check		Check oil every other fill up. Remove the dipstick, wipe it clean. insert it fully and remove it again. If it is low, add oil. To maintain peak performance, change oil every 3,000 miles or 3 months, whichever comes first. Replace oil filter with every oil change.
Exhaust			Check	Look underneath for loose or broken exhaust clamps and supports. Check for holes in muffler or pipes. Replace rusted or damaged parts. Have emission checked at least once per year for compliance with local laws.
Hoses		Check		Inspect belts and hoses monthly. Replace worn, glazed or frayed belts. Tighten them when more than 1/2" of slack can be depressed between the pulleys. Vehicles with spring loaded belt tensioner require no adjustment. Replace bulging, rotten or brittle hoses and tighten clamps. If a hose looks bad, or feels too soft or too hard, it should be replaced.
Lights		Check		Be sure all your lights are clean and working, including brake lights, turn signals and emergency flashers. Keep spare bulbs and fuses in your vehicle.
Oil Filter		Check	Check	To maintain peak performance, change oil every 3,000 miles or 3 months, whichever comes first. Replace oil filter with every oil change.
Power Steering Fluid		Check		Check power steering fluid level once per month. Simply remove the reservoir dipstick. If the level is down, add fluid and inspect the steering pump and hoses for leaks.
Shock Absorbers			Check	Look for signs of oil seepage on struts and shock absorbers, test shock action by bouncing the car up and down. The car should stop bouncing when you step back. Worn or leaking shocks should be replaced. Always replace shock absorbers in pairs.
Tires		Check		Keep tires inflated to recommended pressure (it helps to own your own gauge). Check for cuts, bulges and excessive tread wear. Uneven wear indicates tires are misaligned or out of balance. Keep a record of tire rotation. Rotate at the first 5,000 miles and every 7,500 miles thereafter.
Transmission Fluid		Check		Check transmission fluid monthly with engine warm and running, and parking brake on. Shift to drive, then to park. Remove dipstick, wipe dry, insert it and remove it again. Add the approved type fluid, if needed. Caution: Do Not Overfill
Washer Fluid		Check		Keep windshield washer fluid reservoir full. When topping off, use some windshield washer fluid on a rag to clean off the wiper blades. In the winter months, pay attention to the freezing point of the washer fluid.
Wiper Blades			Check	Inspect windshield wiper blades whenever you clean your windshield. Do not wait until rubber is worn or brittle to replace them. Wiper blades should be replaced at least once per year, and more often if smearing or chattering occurs.
