Most car batteries today are maintenance-free, sealed and can last more than three years. The first sign your battery should be replaced is often trouble starting the engine.
A car tire inflated to 35 pounds per square inch (psi) can lose one psi every month or for every 10 degrees Fahrenheit of temperature change, so your car maintenance checklist should include checking tire pressure. Find the recommended level in the owner’s manual or on a sticker on the driver’s side door jamb. And don’t forget the spare.
Rotate tires every 6,000 miles to prevent uneven wear, replace them when they become worn and have the alignment checked if the car pulls to either side when driving or if you notice uneven tire wear.
Checking and changing oil is critical to keep today’s engines running properly and efficiently. Follow manufacturer guidelines for changing the lubricant – generally, every 3,000 miles or three to six months.
Check the oil level with the engine off and the car parked on a level surface. Open the hood, remove the dipstick, wipe it clean with a cloth or paper towel, then return it to the oil reservoir. Take it out again and see whether the level is within the acceptable range marked on the dipstick. If you add oil, don’t overfill, which can damage the engine.
Checking the automatic transmission fluid is another vital item on the car maintenance checklist. Look for a reservoir marked ATF (automatic transmission fluid) and follow the same steps as monitoring the oil level – only this time, with the engine running. Follow manufacturer’s recommendations for change intervals, about every 30,000 miles.
Replace most engine coolant or antifreeze every 30,000 miles – or every two to three years. Newer formulas, however, may last up to 50,000 miles. To check coolant level, turn the car off and wait for the engine to cool. Locate the coolant reservoir (usually a translucent plastic tank) and eyeball the level of the coolant against the full and low indicators.
Power steering fluid
Power steering fluid should be changed every three years or 50,000 miles. If you have a power steering fluid reservoir, check the level visually; otherwise, follow the dipstick method. Low power steering fluid may indicate a leak, so have your mechanic take a look.
Brakes and brake fluid
Check to ensure that brake fluid levels are within tolerance. How often you need to replace brake pads or other components depends on how you drive and typical driving conditions. Warning signs of a brake problem include noise, vibration or “grabbing” when you apply the brakes. Working on your brakes is a job probably best left to the professionals.
Basic car maintenance suggests changing your air filter each year or every 12,000-15,000 miles. A clean air filter can help your engine “breathe” better and improve gas mileage and reduce harmful emissions.
Replace it annually to help prevent debris from clogging your car’s fuel line.
Windshield wipers and wiper fluid
Windshield wiper care is one of the most neglected basic car care tips. Replace the blades every six to 12 months or whenever the rubber becomes worn. Check the wiper fluid reservoir every week or so and keep it full.
Headlights and brake lights
With your car turned on and parked, have someone walk around to see that your lights are working – headlights, brake and tail lights, turn signals, etc.
Replacing bulbs in today’s vehicles can be a challenge. Have a mechanic do the job, particularly replacing and aiming headlights. A pro also knows if the problem is a blown fuse, not a burned out bulb.
