JimboSti Posted December 17, 2019 Share Posted December 17, 2019 HI all, I have a SG5 Sti that has started to overheat after about 10 minutes. Wondering. If anyone has any ideas? I have checked the coolant and all fine, also no bubbles and can't see it leaking from the exhaust pipe. The fans seem to come on and at that point the revs drop. No custard visable in the engine or oil cap. Steam comes from the black pipe which connects to the radiator once its hot. When the temp rises going up hill if I lift off the gas the temp drops down about a quarter of a dial very quickly. Wondering if anyone has any ideas or if it's a common thing. I've seafched the net but nothing. Thanks Quote Link to comment Share on other sites More sharing options...
JimboSti Posted December 17, 2019 Author Share Posted December 17, 2019 This is the pipe that steam comes out from if that helps Quote Link to comment Share on other sites More sharing options...

Siluro Posted December 18, 2019 Share Posted December 18, 2019 You should not be seeing steam. The cooling system keeps the coolant from boiling by keeping it under pressure. Your losing that pressure if you seeing steam from that hose. Fix the leak. Quote Link to comment Share on other sites More sharing options...
