2cv7 Posted July 29, 2019 Share Posted July 29, 2019 Hi Has anyone out there any experience of running a K series with no bypass circuit.I have an ex race car and have just installed an 82 degree stat (with a bypass hole). It appears to work ok, but needs to be revved a little at tick over to bring the temp down with the fan. On the road it cycles between 76 and 82 degrees when hot. I would install a bypass circuit but the heater pipe on the water rail has been removed. I could just go back to having no stat, but it is a pain to blank off the rad for the cool early morning runs I have to do to get any time in the car. Does anyone have any opinions on any problems this set up could cause, or should I just try to find a new top rail?RegardsElliott Link to comment Share on other sites More sharing options...
rj Posted July 30, 2019 Share Posted July 30, 2019 Remote thermostat would be my answer.I have the PRRT and an external (electric) booster pump. Works a treat!I have no bypass at all. Link to comment Share on other sites More sharing options...

2cv7 Posted August 3, 2019 Author Share Posted August 3, 2019 Thanks for the reply. I am adding a T piece in the top hose and connecting it to the stat housing outlet. I may have made a late night (drunken booboo) by sticking a screwdriver into the head bleed pipe to unjam the valve which freed suddenly, and has now disappeared into the head....
