I have 2002 Chevy Suburban 1500, leaking coolant under truck as I add coolant. new reservoir & water pump gasket, still leaking even cold engine. What could it be?
When trying to find a leak, the best thing to do IMO is to thoroughly clean and dry the engine, especially around the hose clamps, radiator cap, and anywhere else that you have seen the coolant. If it is leaking as fast as you say, there should be some evidence of the source.
