What's the 2004 Chevy Tahoe coolant type?

Most General Motors vehicles will typically work just fine with Dex-Cool, and the 2004Chevrolet Tahoe is no exception. This is the leading recommended coolant type by most major automotive part stores, and You'll find that it comes at a discount versus OEM solutions. However, the most important thing to note is that You shouldn't mix different coolant types. Therefore, if You don't know what's already in Your '04 Tahoe (perhaps You bought it preowned, or You've just got a terrible memory), it's best to do a drain-and-fill. Topping off small amounts of a different type won't typically cause You problems, but adding a different fluid to the tune of anything greater than 15 can cause You serious problems, potentially leading to total engine failure.
