Guest bdl Posted July 12, 2010 Share Posted July 12, 2010 I just had my temp gauge repaired and put it in the car but it is leaking antifreeze around the fitting. :eek: Anyone know what you can put on the threads to seal it and keep it from leaking?Thanks, Brian Link to comment Share on other sites More sharing options...
unimogjohn Posted July 12, 2010 Share Posted July 12, 2010 I usually use the white teflon tape. There seems to be a lot of play in the threads of those fittings, so you have to really wrap it to the point where it may be a bit hard to start. If so take off a couple of wraps and try again. Also, it is important to have a clean hole and fitting. I use a Dremel tool with the right size diameter brass wheel to clean up the threads. Hope this helps.

Guest bdl38s Posted July 16, 2010 Share Posted July 16, 2010 Cleaned it up, put on the teflon tape and it is still leaking. I'm being careful not to tighten it too much in fear of damaging the probe. It even seemed to leak a little from the copper line coming through the nut.Brian Link to comment Share on other sites More sharing options...
RU22 Posted July 16, 2010 Share Posted July 16, 2010 Honest teflon tape is junk! You can get a can of teflon paste at Home Depot..... much better stuff and you can wipe off the extra Unless your building race cars the little can will last your lifetime! :cool: Link to comment Share on other sites More sharing options...
unimogjohn Posted July 16, 2010 Share Posted July 16, 2010 if it is leaking out of the stem/line then it is not sealing against the top of the bulb. You need to carefully and bit by bit tighten the the nut until the weeping stops. Link to comment Share on other sites More sharing options...
Seldenguy Posted July 16, 2010 Share Posted July 16, 2010 Brian-Make sure the bottom of the head recepticle is clean. Don't be afraid to put a little of the teflon paste (sparingly) on each side of the bulb flange and the face of the locking nut. This will assist in the sealing process. --Bob Link to comment Share on other sites More sharing options...
Larry Schramm Posted July 17, 2010 Share Posted July 17, 2010 The best stuff that I like is a Locktite product called Pipe Sealant with Teflon. Link to comment Share on other sites More sharing options...
