Which coolant does a 1990 Chevy 454 SS pick up use?

A 1990 Chevy 454 SS pickup truck should use a 50/50 mix of ethylene glycol-based coolant and distilled water. However, it's crucial to check your owner's manual for the specific recommendations from Chevrolet for that year and model. The manual will specify the type of coolant (e.g., Dex-Cool, etc.) and the correct mixture ratio. Using the wrong coolant can damage your engine.
