Mystery Water Leak

[Thodge]

Nice job on the barn. As for a water pump leak, I would think it would leak all the time and leave some residual coolant on the pump housing and front of the engine. I know that’s what mine was doing before I replaced it. Where is the residual fluid that you’re finding? If it’s in the front crossmember I would suspect that it’s pushing coolant out the overflow for some reason. I had that issue as well because of a missing radiator baffle. You replaced the radiator so that should rule out restricted flow or a missing baffle in the radiator. Possibly a bad head gasket introducing pressure into the system.
