Darned waterpump leaking again 900 1993

posted by  someone claiming to be Gil on  Tue Jan 28 11:32 CST 2003 [RELATED]

After owning volvos for my entire auto-owning life I have replaced my share of waterpumps. I bought a 93 940 last year and this winter the water pump started leaking so I replaced it. Using my usual methods of prying the waterpump up, it still leaked. So I bought a new gasket set, now I replaced those two weeks ago, and today the paper gasket started leaking. Am I missing something? Does anyone use any type of sealant along with the paper gasket? I didn't this time, applied it dry and it was leak free for two weeks. I suppose it could be the highs of 6def f we have been having for the past week that is making it leak? maybe I should re-torque the pump bolts.

    use a little of the blue rtv stuff on the gasket. Like the other post, some grease, especially on the heater hose o ring. I've been there, well twice. Don't retorque, those little m6 nuts will strip.

    Hey Gil:
    What a drag. My mechanics instructor taught me to put a film of silicone grease on both sides of the gasket. Then put the gasket in place and the water pump over the gasket. Then if you have to "jiggle" the waterpump to put it in place it slides over the gasket rather than tearing it or pushing it out of the way. Worked for me.
