jandyb Posted October 20, 2008 Report Share Posted October 20, 2008 I have a 2004 with the thermo in the upper hose. A couple of months ago the thermo popped out of the hose during a race. Probably because of overheating and blocking the excess pipe. I managed to put it back in again and put a couple of zip ties around to keep it in, but now and then it pops out again. Is it possible to buy just the rubber part between the housing and the thermo? In the part lists it doesnt show at all so i supose not... -Jan Quote Link to comment Share on other sites More sharing options...

If the gasket is missing and you can't get one from your dealer, you might try a thick o-ring or other rubber gasket type material (it only has to seal in a few PSI of pressure) and safetywire the clip ends together so they don't spread out and release their grip on the switch. As you found out, it's important to not block off the overflow tube (on the Pro's, it's usually because the hose is over the frame cross tube there and the tank squashes the hose closed when the tank is installed) and the blocked tube can also cause excess pressure to force coolant past the waterpump seal into the transmission case.

peterb Posted October 22, 2008 Report Share Posted October 22, 2008 Hi Jan/Jon, There is no spare part for just the sealing rubber, but.......a friend of mine managed to make one from an old h'bar grip, cutting the end to suit - it worked. With the spring clip in place, you can tie it quite sturdily with wire or cable ties by tieing the spring tops together and then tieing this around the hose to prevent it from popping out. Bye, PeterB. Quote Link to comment Share on other sites More sharing options...
