The air filter accumulates dust and debris and should be replaced to protect the engine and maximize fuel economy. For optimal engine performance and longevity, replace every 1 year or 15,000 miles.

Automatic transmission fluid becomes heat fatigued and accumulates moisture over time which can lead to automatic transmission damage if not serviced regularly. It should be replaced every 2 years or 30,000 miles.

Brake fluid accumulates moisture and contamination from component wear over time and unless replaced every 30,000 miles or 2 years, can cause brake system damage.

Over time the Cabin Filter(s) will accumulate dirt, pollen and debris which can leak in to the passenger compartment if left unchecked. They should be replaced every year or 15,000 miles.

Engine coolant breaks down, gets rusty and becomes contaminated with debris from component wear over time and can cause engine or cooling system damage if not replaced every 2 years or 30,0000 miles.

Differential fluid breaks down and becomes contaminated with moisture over time and can lead to differential damage from a lack of proper lubrication. It should be replaced every 2 years or 30,000 miles.

Drive belts crack and become glazed over time and can squeak or even break. They should be replaced every 45,000 miles.

The Fuel Filter becomes restricted as it accumulates debris from filtering the fuel which, can lead to perfomance problems and early fuel pump failure. It should be replaced every 2 years or 30,000 miles in vehicles where it is replaceable.

Spark Plug terminals wear down over time and can lead to engine misfires and increased exhaust emissions. Replace according to the vehicle manufacturers recommended replacement interval.

Inspection of wheels and tires, rotate tires, check and adjust air pressures

Replacement of the Engine Air Filter and the Cabin Air Filter (where applicable) is performed, along with an inspection of the drive belt and drive belt tensioner.

Replacement of the Automatic or Manual Transmission Fluid is performed.

Adjustment of the valves should be performed whether they are noisy or not. The Valve Cover gaskets will be replaces as part of this job.

Spark plugs are replaced.

Engine Coolant Replacement is performed.

On engines with adjustable valves, the valve train clearances can become improper which can lead to engine damage. The valve clearance should be checked and adjusted every 30,000 miles.
