That's the next job of a series of things i had to do on the good old Jeep. Over the last 6 months or so i had an ever increasing puddle of coolant under it. By just looking at it, it was quite hard to tell where exactly it comes from, but it was was pretty clear that either water pump or thermostat housing are the culprits.
My favourite was the thermostat housing as this is quite a weak design and sometimes hard to get sealed properly.
next one was the shaft seal of the water pump.
Well,... it turned out it's something else .... enjoy the video.

Part 1 shows how we got things apart, part 2 shows surface prep and re-assembly.
