What type of coolant is used on a 1996 Chevy impala?

A 1996 Chevy Impala should use a 50/50 mixture of ethylene glycol-based coolant and distilled water. It's crucial to use a coolant that meets the specifications recommended by General Motors (GM) for that year and model. Checking your owner's manual is the best way to confirm the exact specifications and any additional recommendations, such as the use of a specific type of antifreeze/coolant. Using the incorrect coolant can damage the engine.
