Mitsubishi Eclipse Coolant Type

The Mitsubishi Eclipse uses manufacturer-specific coolant — typically long-life OAT or HOAT formula. Never mix different coolant types. Check the year breakdown below for your specific coolant color and capacity.

Fluid type and capacity can change by engine, drivetrain, and transmission. Verify the exact branch before filling anything.

Frequently Asked Questions

What type of coolant does a Mitsubishi Eclipse use?
The Mitsubishi Eclipse coolant type depends on the model year. Newer models use long-life OAT or HOAT coolant (often pink, blue, or orange). Older models use traditional green IAT coolant. Never mix types — check the specs below for your year.
How much coolant does a Mitsubishi Eclipse hold?
The Mitsubishi Eclipse cooling system typically holds 6-10 quarts total. A drain-and-fill replaces about 50-60% of the coolant. For a full system flush, you'll need the complete capacity amount plus extra for bleeding.
Can I mix coolant colors in my Mitsubishi Eclipse?
No — mixing different coolant types can cause gel formation, clogged passages, and overheating. If you don't know what's in the system, do a complete flush before adding new coolant. Use only the manufacturer-specified type.
How often should I change coolant in my Mitsubishi Eclipse?
Modern Mitsubishi Eclipse models with long-life coolant can go 100,000 miles or 10 years before the first change, then every 50,000 miles. Older models with green coolant need changes every 30,000 miles or 2 years.
