jimoshel Posted January 31, 2011 Share Posted January 31, 2011 Put some sealer on the threads and tighten it until snug. Link to comment Share on other sites More sharing options...
pug Posted January 31, 2011 Author Share Posted January 31, 2011 What kind of sealer and it is going to be hard to get surface dry. I guess the washer is a bad idea. thanks Link to comment Share on other sites More sharing options...
comanche12 Posted January 31, 2011 Share Posted January 31, 2011 yeah washer is bad idea. Try Teflon tape? They work great for seal. Not matter if its go be wet. its will seal the thread anyway. Link to comment Share on other sites More sharing options...
pug Posted January 31, 2011 Author Share Posted January 31, 2011 The teflon did not work. I can tighten it down pretty snug wants it gets under pressure starts leaking. Then starts cutting out and backfiring because of cps is getting wet. Link to comment Share on other sites More sharing options...

comanche12 Posted January 31, 2011 Share Posted January 31, 2011 Yes just wrapped it once. hmmm interesting well its work on me? :dunno: teflon paste not tape? wait until the paste get dry then bolt it down? Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 31, 2011 Share Posted January 31, 2011 The temp "switch" (I think you mean sender unless you have idiot lights?) gets it's ground from the threads to the block. Wrapping tons of teflon tape around it kills the ground - temp gauge don't work. Just get a new one. Link to comment Share on other sites More sharing options...

I'm sure there will be some metal available to connect the ground? like top flange of bolt not the thread? Link to comment Share on other sites More sharing options...

Not saying it will happen in all cases, but it could happen. My FSM even has a warning not to used teflon tape because of the possibility. Link to comment Share on other sites More sharing options...
comanche12 Posted January 31, 2011 Share Posted January 31, 2011 alright sorry guess i got lucky in one shot. so your recommend is just replace new sensor? No, if you have already replaced the sensor and there are no leaks and the temp gauge is working, I'd leave it be. For single-wire sensors that use thread contact for grounding purposes I use the hi-temp Permatex sealant, but sparingly. No worries for two-wire sensors though. :cheers: Link to comment Share on other sites More sharing options...
pug Posted January 31, 2011 Author Share Posted January 31, 2011 Yes it is a gauge not a idoit light. Gauge works it just leaks from the sender. Does anyone know what the size bolt would fit in there until i can get a new sender. thanks Link to comment Share on other sites More sharing options...
