DarylG40 Posted May 16, 2011 Report Share Posted May 16, 2011 Started to have a few problems with the girlfriends lupo. Its a 1.4 E AHW. The car over heated the other day due to the fan not kicking in. So i replaced the water pump as it had the plastic one which was nearly seized. Also put a new stat in as that fell apart when i took it out.Now its all back together Ive got lumpy idle, Top hose hot bottom cold, All water hoses are really hard to touch until you take the expansion tank cap off and nearly blows your hand off even when you leave the car for a few hours.I'm thinking the pressure could be down to head gasket putting exhaust gasses into water system due to the over heating?Bottom hose still being cold due to new stat not working or blocked radiator?Idle lumpy - sensor by the thermostat, dirty throttle.other than that it drives fine and the fan kicks in. Would be great if anyone has any other suggestionsThanks Daryl Quote Link to comment Share on other sites More sharing options...

Defcon5 Posted May 16, 2011 Report Share Posted May 16, 2011 Yeah, do some photos. No oil in the coolant? Quote Link to comment Share on other sites More sharing options...
DarylG40 Posted May 16, 2011 Author Report Share Posted May 16, 2011 Nope no oil in the coolant. Before i took the head off i took the plug off the coil pack and took the top expansion tank hose off and cranked it and she was pushing out exhaust fumes.

Defcon5 Posted May 16, 2011 Report Share Posted May 16, 2011 Have you fixed why the fan wasnt coming on? Or was it the stat sticking shut? Quote Link to comment Share on other sites More sharing options...
