Has anyone changed a main water pump un a universal m25xp diesel, mine has siezed and broke fan belt, is this difficult, does the old one come right out and is a new one easy to install, any help would be appreciated. I am mechanically able just want to know if there is anything I should be careful about when taking off and putting new one in. Thanx
Main water pump

Hi,
I have a C30 with the M25 engine which is at least similar to your engine. I replaced the main water pump in my engine after the bearing failed. It was a straightforward job off and on. The only sticky part for me was that the hose that exits the pump and delivers water to the heat exchanger was ruined in disassembly. I was unable to purchase a new one with the 90 degree bend. I was able to cobble together a replacement using a pair of 90degree copper tubing fittings and straight hose. It has lasted more than ten years. Perhaps the hose is now available but I wouldn't count on it. Take steps to preserve the original hose if you can.
Good luck!
Good advice.
That hose is a 1" to 7/8" 90 degree hose. Instead of paying marine prices, go to an auto store and ask for one.
I used to have a link to it, I'll start looking for it.

If you take that picture to an auto store they should know. You'd want the guy who graduated high school in 1990, not the new guy
who can only look up parts from a computer.
Thanks for the reply and the info, have to change it in the water but sounds like it should be a not to bad job, always appreciate the advice from someone who has a little knowledge of what to do. Again thanks
