MikeP Posted February 10, 2014 Report Share Posted February 10, 2014 Went out in my lupo for a drive earlier as i had nothing to do, drove for about 20 minutes tops and the temperature had increased to over 110 degrees so i nursed it home, checked the expansion tank for the coolant and it was on the maximum line, opened the expansion tank to check that there was compression which there was, felt the two hoses going to the thermostat to see if they was both hot or not but it was only the top one which was hot and the bottom hose was cold, anyone have any clue what it could be and is this a common fault? Its the 1.4s (not the sport) Quote Link to comment Share on other sites More sharing options...
danoid Posted February 10, 2014 Report Share Posted February 10, 2014 Hmm, if your coolant level hasn't dropped, and not mirky inside, then a head gasket can be ruled out pretty much.Could be faulty water pump or failed thermostat not opening correctly Quote Link to comment Share on other sites More sharing options...
