trogboy 17 Posted October 22, 2006 I have a thermo switch which I need to mount in a hole my thermosat housing. The switch comes with a threaded brass base but the thread size was an odd one which I couldn't get hold of so I got a friend to turn down the threads on a lathe to make the switch a tight push fit into the hole in the housing. Unfortunately he cocked up the final cut so the switch is a little loose and needs to be held in by a grub screw. This also means that there is very little physical contact between the switch and the housing which isn't ideal so i'd like to fill the gap with some thing with a high conductance. Chemical metal comes to mind but I'm not sure if it contains real metal of some sort or if it is just a metallic coloured epoxy. The last thing I want to do is insulate the switch from the thermostat housing. Any ideas? Share this post Link to post Share on other sites

trogboy 17 Posted October 22, 2006 What happens when the cooling system presurises and forces the glue out, along with all the coolant? The hole doesn't penetrate into the coolant pathways inside the housing - it's just a dead end. Share this post Link to post Share on other sites
pugrallye 0 Posted October 22, 2006 What happens when the cooling system presurises and forces the glue out, along with all the coolant? I have seen glue used by a certain race company to 'overcome' certain problems like remanufacturing inlet manifold tracts (that is only one example and not a one race wonder) , never ever have they had any problems and his surname starts walk... considering most modern cars use glue in all sorts of high tensile situations, you should not have a problem with a lowly coolant circuit Share this post Link to post Share on other sites
