Cchase Posted September 24, 2021 Share Posted September 24, 2021 Hey Folks, I have a 2.5 N/A diesel that seems to be loosing coolant. Before driving I fill through the overflow tank until this is half full. After a drive the tank is empty and the rad is down. There are no obvious leaks from the hoses, the dipstick oil is not 'moussey', the exhaust is not white and it accelerates and operates as expected. I am thinking that I have a head gasket leak, but want to check here with the collective wisdom of the tribe to make sure there is not another area to look into. The engine was rebuilt about 5 years ago and I have gone maybe 3000km since. Any advice or guidance will be greatly appreciated. Best, Colin Quote Link to comment Share on other sites More sharing options...
western Posted September 24, 2021 Share Posted September 24, 2021 Any crystal type remains below the water pump spindle, there is a drain hole between the 2 water pump bearings & seals in one gives up the coolant can escape through this 'tell tale' hole Quote Link to comment Share on other sites More sharing options...
