Mitsubishi Maintenance Procedures - Common Additional Services

Mitsubishi Automatic Transmission Fluid Change

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.

Mitsubishi Automatic Transmission Fluid/Filter Change

Automatic transmission fluid becomes heat fatigued and accumulates moisture over time which can lead to automatic transmission damage if not serviced regularly. The filter should be replaced at this time a well. This service should be performed every 2 years or 30,000 miles.

Mitsubishi Brake Fluid Replacement/Flush

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.

Mitsubishi Cabin Air Filter Replacement

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.

Mitsubishi Coolant Replacement/Flush

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.

Mitsubishi Differential Fluid Replacement - Rear

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.

Mitsubishi Manual Transmission Fluid Change

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

Mitsubishi Rotate Tires

It is important to rotate the tires from front to rear every 5000-7500 miles so that they wear evenly. This may not be possible on some vehicles because of directional tread design or rim size differences.

Mitsubishi Spark Plug Replacement

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.

Mitsubishi Transfer Case Fluid Replacement

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

Mitsubishi Scheduled Maintenance Parts

In order to run, the engine needs a precise mixture of fuel and air. When outside air is drawn into the engine, the air filter prevents harmful dirt and debris from entering the system.
The alternator belt is a flexible rubber belt driven by the engine to power the alternator. The alternator belt can be the common "V" profile or the more modern flat-ribbed style.
The cabin air filter prevents dust, pollen, and other debris from entering the passenger compartment through the climate control (HVAC) system.
Coolant is the fluid that flows through the engine’s cooling system. Its main purpose is to transfer heat generated by the engine to the radiator so the engine doesn’t overheat.
These belts can be used individually or grouped together as part of the belt/pulley system that is driven by the engine crankshaft to run such items as the air conditioning compressor, alternator, and power steering pump.
Engine oil provides lubrication for all internal moving parts of an engine. It also helps conduct heat away from these components.
Gear oil is thicker than engine oil or transmission fluid and is formulated specifically for gearboxes, e.g. manual transmissions, transfer cases, and differentials.
A hose clamp attaches and seals a rubber hose to a fitting.
After the radiator has cooled the coolant, the lower radiator hose carries it from the radiator back to the engine.
The oil drain plug gasket seals the oil drain plug where it connects to the oil pan.
The engine oil filter removes contaminants from the engine oil before it circulates throughout the engine.
The spark plug uses the energy produced by the ignition coil to generate the spark necessary to ignite the air/fuel mixture in the combustion chamber. The platinum/iridium spark plug uses harder metals on the electrodes, which increases their life to over 100,000 miles in most applications.
The upper radiator hose carries hot coolant from the engine into the radiator for cooling.

Car has 200,200 mi on it and was told not to flush the transmission due to it never being changed. However, it was said that I just drop the trans fluid pan, empty it, change filter, replace the fluid without flushing the transmission. Is this true?
