What type of coolant does a Chevrolet Express use?

The Chevrolet Express 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 Chevrolet Express hold?

The Chevrolet Express 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 Chevrolet Express?

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 Chevrolet Express?

Modern Chevrolet Express 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.
