NV Zeno Posted June 2, 2006 Share Posted June 2, 2006 '83 EA81 non-turbo: After much procrastination, I've decided to finally replace my water pump. Got a replacement unit and gasket from NAPA. The "...Subaru Alive" book sez to use silicone gasket sealer, but I don't have any laying around. What I DO have is the spray-type "Copper Coat Gasket Compound". Will the copper stuff be OK to use for this application? I have no problem getting the silicone, I'm just looking to save a trip to the parts store:rolleyes: .

Caboobaroo Posted June 2, 2006 Share Posted June 2, 2006 best bet would be the silicone IMO. I don't know much about the copper spray though.... Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 2, 2006 Share Posted June 2, 2006 I've used RTV many times - both with and without a gaskets. Never had one leak yet. Just don't use too much. 1/8" bead is more than enough. GD Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted June 2, 2006 Share Posted June 2, 2006 Dont think Copper spray is gonna give you that water tight seal the gaskets gonna want. Better play it safe and use the silicone. -Brian Link to comment Share on other sites More sharing options...
