Other Maintenance Parts

Many maintenance parts are mistakenly seen as non-critical. Though not true "tune-up" parts, the functions of these parts can definitely impact the benefit of any tune-up. Plus, as emission laws have gotten more stringent, these parts have become essential - if you want your car to pass emissions the first time around.

Oxygen Sensor (O2 Sensor): Your oxygen sensor(s) should be replaced at the recommended intervals. A worn oxygen sensor drastically changes engine settings.

Vacuum Hoses: Many major systems depend on manifold vacuum for signals and function. All vacuum hoses should be checked and replaced as needed. Even a slight leak can cause major problems with performance; in some cases, the car won't even run if there's a vacuum leak.

Temperature Sensors: These sensors control the fuel injection system, cooling system and even the exhaust system. And they can definitely be a cause of poor performance problems.

A Few Important Things to Remember:

Heed these tips and you're well on your way to extending the life of your car and improving its overall performance - especially gas mileage and emissions:

Tip #1: General overall cleanliness of your engine is the best preventive maintenance you can perform on your car. A clean engine runs cooler and is much less likely to cause premature failure of other parts. It's also easier to work on.

Tip #2: Regular routine replacement of all filters, lubricants, coolant and the other parts noted here is critical. Use the mileage guidelines shown as your benchmark. Sensing and mechanical tolerances have become so tight even slight variations can create drastic performance changes.

Tip #3: Know your car's systems and particular requirements before starting any project. Do not attempt to fix what you don't understand.

Tip #4: Remember that some improvements may not take effect right away if your car's computer is designed to learn and adjust. The computer may need to see various parameters before making any permanent setting changes.
