Tommyk Posted March 28, 2015 Share Posted March 28, 2015 Hi guys basically since my car was mapped at td and had a new triple core half rad I've had heating issues. It's not down to the engine as this is the third engine it's happened on now. Basically if I give it some thrashing temp gauge goes rite up and heaters go cold and then heaters come warm again and it goes back down. Also spits water out the cap or somewhere but I've put a new high pressure cap on and all bleed up perfect but still no difference any ideas? Quote Link to post Share on other sites

Ryan_EP82 GT Posted March 29, 2015 Share Posted March 29, 2015 Airlock in the coolant system? Have you bled it to see if that could be an issue?also try a low temp thernostat with your half rad for future Quote Link to post Share on other sites

Tommyk Posted March 29, 2015 Author Share Posted March 29, 2015 Yh it's bleed up fine and it's had 3 different water pumps obv with the 3 engines so not tht. I wondered if a bad map could cause this and unless it's a faulty rad Quote Link to post Share on other sites

russ78 Posted March 30, 2015 Share Posted March 30, 2015 i had an issue a while back with the fan polarity being the wrong way round check when your fan cuts in its spinning the right way Quote Link to post Share on other sites
