Vehicles are a big investment for families – usually the second highest valued item in a household after the home itself. While the purchase price for cars, trucks and SUVs keeps going up, the cost of maintenance is holding steady or even dropping for most vehicles. Better materials, sophisticated computers and other advances increase reliability and allow less frequent oil changes, tune-ups and other service.

Owners can do some of the work themselves to lower maintenance costs even further. Anyone interested in saving money and increasing pride of ownership by doing their own work can spend just a few minutes and accomplish the following four maintenance tasks easily, without any expensive tools or training.

* Cabin air filter replacement – The air conditioner is cranked up on those hot summer days. The cabin air filter keeps the air blowing through the heat and air conditioning ventilation system clean, and it should be replaced at least once a year. But in areas of the country where there is a lot of pollen or dust – from dirt roads, construction projects or even arid conditions – it’s a good idea to replace this filter more frequently.

“Cabin air filters are usually easy to install, but installation will vary between cars,” says Tom Taylor, engineer and vice president of RockAuto.com, an online auto parts retailer. “Some filters are behind the glove box, and others are accessed through the cowl panel below the windshield.”

Check your owner’s manual to see if there is information on replacing the cabin air filter, or visit RockAuto.com to find installation instructions provided by filter manufacturers.

* Headlamps and tail lights – When a headlamp or tail light burns out, you may be surprised to discover how easy it is to replace these bulbs. For most vehicles, installation of headlamps is from the engine compartment. Just unplug the electrical connector on the back of the bulb, unscrew the large plastic ring that holds the bulb in place and pull the bulb out. Because headlamps are usually halogen lights, be sure to wear gloves or use a cloth to avoid getting fingerprints on the bulb. Oils from your hands can shorten the life of the bulb.

Tail lights are similar – usually you can gain access through the trunk of the vehicle underneath the trim material.

* Wiper blades – Trying to see the road through a streaky window is almost as bad as trying to see the road in a heavy rain shower. The quality of the blade purchased will determine how long the blade will last and how well it will perform in clearing the windshield of rain.

“It is now easy to choose wipers that are better than what originally came on the car,” Taylor says. “There are longer-lasting blades, winter blades that resist freezing to the windshield and beam-type wiper arms that hold the blade more firmly on the glass.”

Higher quality blades tend to cost more, but drivers will appreciate the durability and clarity they provide. RockAuto.com is promoting a wiper wholesaler closeout for top-quality blades at extremely low prices. Once you have your blades purchased, just follow the included directions on how to install them.

* Engine air filter – These air filters keep the oxygen supplied to the engine’s combustion chambers free of dirt and other contaminants. Clean air is needed to optimize the engine’s performance and extend its life. Manufacturers recommend replacing an engine air filter every 12,000 miles driven.  However, it will also depend on the car’s model and how dusty the environment is. This filter is typically located under the hood in a large, rectangular, plastic air filter housing. Remove the four bolts or clips around the edges and then lift the dirty filter out.

These maintenance tasks are ongoing, but they become even easier with repetition. DIYers save money and time when they handle them at home.
