RRC V8 Temperature Sender

Feb 15, 2005 1 Replies

What I thought would be a half hour job to replace the sender has now turned into a major operation. The sender is seated very firmly and the idiot that installed has rounded the hexagonal parts. I have continued the rounding part in my efforts to get it off but no success. At this stage I think the best bet would be to take the inlet manifold off so that I can tackle this with a large vice grip.



The question is: I have recently replaced the manifold gasket with a composite one. Can I use this again or do I buy a new one? I suppose I should inspect it first. Maybe I could use a bit of jointing compound when reassembling?



Any advice appreciated. Thanks Paul


NO, it WILL leak. It's only designed to be compressed the once. Same for the rubbers at either end. For best results, apply a thin smear of blue hylomar sealant to the manifold gasket - around the water ports only. As for your water sender, try and get a pair of stilsons onto it to crack it loose, (removing ancilliaries and hoses as required) then mole grips will turn it ok. I've never had to remove a manifold to do one, if it's that tight then you'll have issues holding it when off the engine, with the possibility of damaging the gasket sealing faces.
