When looking at a vehicles engine, an air filter is a very important component. Without the air filter harmful debris, dirt, and other contaminants would be able to enter your engine or vehicle’s cabin. Many do not realize it, but having an old or dirty engine air filter can be just as bad as not even having one. All vehicles have different recommendations for the amount of time you wait to get your air filter changed, but these are common rules for when it's time to change that work across all vehicle types - if it's been more than three year. It's been over 30,000 miles. Or black areas on the section of the filter where outside air enter have appeared.
The greatest cause of summer breakdowns is overheating. The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of antifreeze and water is usually recommended.) DIYers, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
A marginally operating system will fail in hot weather. Have the system examined by a qualified technician. Newer models have cabin air filters that clean the air entering the heating and air conditioning system. Check your owner's manual for location and replacement interval.
Batteries can fail any time of year. The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check the fluid level monthly.Avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
