Bartman Posted June 2, 2006 Share Posted June 2, 2006 I have several unused vaccum and heater hose fittings on my engine that need to be blocked off. I've been using these rubber caps that I found at Pep Boys, but they only work for a short time before they start cracking and eventualy leaking. I had a cap on a water pump outlet that gave out a while back and anti-freeze start shooting out everywhere. Does anyone have a better solution? I'm thinking that a small section of hose with some sort of metal plug might work better. Quote Link to comment Share on other sites More sharing options...

Bartman Posted June 2, 2006 Author Share Posted June 2, 2006 The water pump outlet that I want to block off has a small metal pipe that is press-fit into the aluminum water pump housing. I've read where people have popped out these metal tubes and threaded it to install a threaded plug or just put in a freeze plug without threading it (the opening is 3/4" diameter). I went to my local auto parts store and bought one of those rubber expansion plugs that I'm going to try and use to cap my water pump opening. I think it will work better than a cap and it will look nicer too. Quote Link to comment Share on other sites More sharing options...
