Water pump & o ring gasket

[Kim K Kaiser]

Got pump put bk on.  Poured in some AF into the pump.no sign of leak but only poured in bout 2 or 3 quarts.down the crossover tude directly into pump.  Dnt kno if that will indicate further leak or not but thought worth a try before re hooking everything bk up.

Regardi g fat o ring.  I had a little bubble up there on first fill up, wondered if two would work.  Anyone tried that? 2 w sealant?

Yes,  i nvr got it started and the leak was coming out of bottom of seal.  Unless pressure builds during filling, shoukdbe any pressure shouod therr?

Other thing is, these are like fat little do nuts, as opposed to  a sk8nny little o ring.   . 2 is ok?  Less goop

I dealt with the same leak when I changed my water pump a few years ago. Rather than using 2 O-rings, I turned a sleeve that fit on the crossover tube fitting and forced the O-ring down into the water pump and it worked great. I think I ended up making it about 1/8" thick. You could probably get the same effect by using washers if you can find some the right size.
