B7800 Water pump replacement questions

[BlueArc]

Hello everybody,

I'm new to the forum and this is my first post. I have owned my B7800 for about a year now and the water pump has started to leak. I plan to replace the pump myself and was curious if anyone on the board has done this job? I searched and couldn't find a DIY or writeup on the job, any advise or hints would be great! Thanks in advance!

It's not hard but if you're not the original owner and have no idea of the machines' age.
You could run into lots of issues.
I suggest that you:
1) Recore and pressure test the radiator.
2) Replace both coolant hoses.
3) Replace the thermostat.
4) Carefully, very carefully, remove the studs of the water pump.
They'll more than likely snap on you
Be ready to drill and heli-coil the holes.

It's a messy job but not all that difficult.
If you've done automtoive, you'll be fine.

Awesome advice, thank you very much! I was planning to replace the thermostat, but bummed to hear about the WP studs, I hope I can avoid that!
