MTSuby Posted October 6, 2006 Share Posted October 6, 2006 I'm replacing my water and oil pumps this weekend, just wondering, other than the gaskets, if it's necessary to have any sealants on bolts or anything. Also, if anyone has any info that might be handy and isn't covered in the repair manual. I printed the timing belt instructions from the USRM, but other than that? Anything?

GeneralDisorder Posted October 6, 2006 Share Posted October 6, 2006 I don't even use a gasket anymore. Just RTV and go. GD Quote Link to comment Share on other sites More sharing options...
BoostedBalls Posted October 7, 2006 Share Posted October 7, 2006 Be oh so careful with RTV on the oil pump, one little RTV booger can destroy your engine. Make sure your surfaces are cleaned with brake cleaner before doing it. I personally would never use RTV on a pressurized oil system. I used to be the tear-down guy at an engine shop and I saw too many spun main and rod bearings from the RTV Booger Devil. As far as the coolant system, go for it. You might plug up a passage in the radiator or a steam hole somewhere, whoop-d-doo. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 7, 2006 Share Posted October 7, 2006 Oh - yeah didn't see the oil pump part of your post. Use anereobic sealant for that if you need anything. RTV is a no-no on anything but the cooling system IMO. I don't really use it anywhere else on a soob except the cam cases/valve covers.

Snowman Posted October 7, 2006 Share Posted October 7, 2006 Don't use any sealant on the oil pump. Just coat the O-ring type seals with oil. I usually use the water pump gasket with some spray-on copper stuff on there to fill any little voids. Quote Link to comment Share on other sites More sharing options...
nkx Posted October 7, 2006 Share Posted October 7, 2006 dont go too nuts with tightening the bolts for the oil and water pumps. use a thumb ratchet if you have one! Quote Link to comment Share on other sites More sharing options...
kayakertom Posted October 7, 2006 Share Posted October 7, 2006 I clean and wire brush all the bolts I take out and then use a light coating of moly/graphite engine assembly lube on the threads. Quote Link to comment Share on other sites More sharing options...
Marck Posted October 7, 2006 Share Posted October 7, 2006 I would use aviation sealant on the waterpump with the gasket. The oil pump just needs a coat of oil on the o-rings. Good luck. Quote Link to comment Share on other sites More sharing options...
Bizangous Posted October 7, 2006 Share Posted October 7, 2006 I use RVT blue on the water pump along with the paper gasket. I put the RVT on the waterpump side and it helps the gasket stick to the pump and makes it easy to put the bolts threw. Quote Link to comment Share on other sites More sharing options...
MTSuby Posted October 10, 2006 Author Share Posted October 10, 2006 Well..let's hope I did it all right. Thanks for the posts, but unfortunately I wasn't around to check any of them, since I was doing it during those times. So far no leaks coming out of anywhere. Mostly I'm just amazed it actually started back up and runs. Quote Link to comment Share on other sites More sharing options...
daeron Posted October 11, 2006 Share Posted October 11, 2006 I clean and wire brush all the bolts I take out and then use a light coating of moly/graphite engine assembly lube on the threads. good tip, but i think using anti-seize compound might end up cheaper. i may be wrong, come to think of it i dont think ive ever actually PURCHASED either. large families are great (i have four brothers, a father, and an uncle and the only one who isnt a "car guy" is the professional mechanic:eek: ) also, what about using a thin layer/application of lightweight grease for the oil seals and o-rings to facilitate proper sealing when installing, and to hlep make the gasket stick? thats just something that ive always done when it was an option myself... any qualms?
