Jeep recommends tune-up items between 20,000 miles and 150,000 miles. We will remind you when these items need completion.
Jeep may only specify a spark plug change or filter replacements at a given mileage. But as part of our commitment to your safety, our technicians will also check your brakes and hoses and look for worn-out belts, fluid leaks, and other vital issues.
The engine control computer (ECM) assumes items such as spark plugs are operating as they should. By keeping the replaceable parts within parameters, the ECM’s adjustments will are based on accurate information. If you do tune-up items when Jeep specifies, the ECM will be happy and provide you with the best performance and fuel mileage of which it is capable.

Historically only expensive vehicles had cabin air filters; today, nearly all cars have them. The OEM cabin air filter will do an excellent job of preventing airborne dirt from entering your vehicle. We can install a HEPA filter to exclude the tiny particles those with allergies abhor. Jeep recommends changing the cabin air filter every 20,000 miles. It would be best if you considered replacing the cabin air filter more often in harsh conditions.
The engine air filter prevents the engine from ingesting airborne dirt to avoid damage to internal parts. If the engine air filter clogs, sufficient air is prevented from entering the engine at the amount required. Power and fuel mileage are affected. Jeep recommends an engine air filter change every 30,000 miles. Under some conditions, it should be changed more often. Our technicians will inspect your car’s filters and recommend a change interval.
Engine coolant prevents overheating, but it is just as essential to maintaining your engine at a temperature that meets the parameters set by the ECM. Smog controls require the engine temperature to stay inside these boundaries. The part that regulates engine temperature is called a thermostat. We frequently switch this component at the time of a coolant change. If the thermostat malfunctions, your car may not pass a smog test. Besides controlling engine temperature, coolant includes anti-rust additives. This is an important benefit for your iron engine block. Jeep recommends coolant replacement when the anti-corrosion chemicals are spent every 100,000 miles.
Jeep recommends spark plug replacement every 100,000 miles. Putting off spark plugs replacement may result in substandard running, poor fuel mileage, hard starting, and smog test failure.
Transmission fluid holds contamination and eventually becomes inundated. Contaminated transmission fluid will cause rough shifts; if you think transmission repair is in your future, a transmission flush may solve your problem. Jeep specifies 150,000 miles for this service. Differential and transfer case fluid also hold contamination until you change it. Jeep specifies a 120,000-mile change interval.
