OK, this might sound a little crazy, but I swear my recently acquired '94 coupe is running better after a coolant change, of all things. I never thought of coolant as any sort of performance aspect. But I am positive my car is running better now.. smoother idle, snappy acceleration.
Has anyone else ever noticed improved engine performance after a coolant change? Or am I just imagining this?
My other car is a minivan!
