Water pump leak below thermostat

[merc123]

I did a coolant flush to ELC and replaced the thermostat a few months back and noticed that I had a coolant leak. I assumed the housing was leaking so I eventually got a new thermostat housing and new upper hose. Today I checked it and it's still leaking but not from the housing. It's leaking under the housing where the water pump bolts to the block. I checked the bolts were tight and they were so I'm assuming I need a new gasket?

Guessing if it's a new gasket I might as well replace the pump since it's gotta come out. I have 141k on it.

is it leaking out between the front cover and the block or the pump and front cover?

either way put a pump in it and check the front cover for signs of cavitation, if it decides to let go you may loose a fan in the process.

I used just a new gasket and still leaked at the thermo housing, pump, and lower metal hose. Took it all off and put sealant on all the mating surfaces. Blue I think.

Went ahead and replaced the pump. Working just fine now.
