I recently purchased a '95 M3 from a private owner. Come to find out he had a water-pump failure, and had to have it towed to the dealer and the WP replaced. I wonder if the engine overheated or if a warning light was probably set before any engine damage occured. What happens when an E36 begins to overheat? I assume there is a warning light...is there anything else that would prevent/discourage the driver from causing serious damage???? Thanks for the help.
