subpilot Posted August 31, 2005 Share Posted August 31, 2005 Has anyone tried to thread the outlet side of the water pump so a hose fitting could be used instead of the o-ring connection? Is there another alternative to the o-ring connection? Thanks in advance, Subpilot Quote Link to comment Share on other sites More sharing options...
calebz Posted August 31, 2005 Share Posted August 31, 2005 Holy carp! Another Subaru in North Texas? After looking at a spare waterpump, I don't think the housing looks very condusive to taking a thread? Just out of curiousity, why would you want to?

NorthWet Posted August 31, 2005 Share Posted August 31, 2005 Nitpick: That is the inlet to the waterpump. You *might* be able to epoxy something in, but any fitting you are likely to come up with to do this will reduce the diameter of the tube.

subpilot Posted September 1, 2005 Author Share Posted September 1, 2005 Thanks all. My application is in an airplane and I read a thread last week of someone having a leak at this connection. This has been a concern of mine for some time because a leak there could quickly drain my coolant. However, after reviewing my manuals again I see it is on the inlet side and I feel better about that. With the exception of the TD04 and intercooler I am trying to leave everything as stock as possible so I will continue with this connection as is and keep an eye out for any problems showing up on the board. Thanks again everyone. Subpilot Quote Link to comment Share on other sites More sharing options...
MorganM Posted September 1, 2005 Share Posted September 1, 2005 Leaking there is usually due to the O ring failing or pipe rusting and failing. Find yourself an inlet pipe in good condition and a new O ring. Quote Link to comment Share on other sites More sharing options...
