Re: OBS Water Pump Fun
I did the waterpump in my 97 it was pretty dang easy as far as waterpumps go.
The hard part for me was getting the fan clutch off of the old waterpump, I had to clamp the old pump down to my trailer and it took a 8' breaker bar to free it. The hub on my fan and clutch has been bitched up by people using an air chisel on it. It was NOT easy...in fact I removed the whole pump with fan attached.
I also replaced the thermostat at same time and rebuilt my oil cooler. Very good idea to rebuild the oil cooler now and replace the block heater since you will have to drain alot of coolant from the block.
The stock thermostat housing sucks, its "sheet metal" and they stretch and leak (more like hard to seal up)
SO they make aftermarket water jackets from billet or you can put a aftermarket re-enforcing ring on the stock piece that will help it seal.
I now have a new waterpump (AC
New serpentine belt
New fan clutch (Motorcraft)
Rebuilt oil cooler (Ford O ring kit)
New block heater
and new radiator hoses
All of that is a good idea when considering changing the waterpump on OBS
Oh yeah and dont forget to add the diesel coolant additive to your coolant when done
For the battery cables, consider converting your stock cables to use copper lugs..I did and I am very happy with the results. All the other 7.3 trucks around here are constantly having battery terminal issues, not my 97
