    Hey!

    So there's a coolant leak coming from where the collant pump is, how could I determine if it's the pump itself or just a gasket that need changing?

    And in both cases, how complicated would that be?

    Thanks!

    It’s probably the waterpump. Is it a 6 or 8 cylinder? It’s not that hard to change. There’s alot of how to veido’s on the net. You can surch here as well.

    There is a weep hole on the underneath "snout" of the water pump. When the internal seal goes bad, it will leak out of that weep hole. Also, with the motor not running, grab the fan and see if it "wiggles". The wiggle will indicate the water pump bearing is bad or heading that way.

    So it is def wet below, the thermostat housing is also slightly leaking as it seams the gasket is dead. But mostly the below of the water pump is very wet even days after the engine ran last.

    But the fan does not wiggle AT ALL.

    Any ideas?

    Thanks!

    The seal in the water pump can still go without the bearing going bad too, since you mentioned the thermostat housing/gasket is leaking, why not change gasket/reseal that first? Process of elimination, once you fixed that, then you will know for sure whether or not the water pump is leaking too.........good luck!
