RosieLuke Posted March 21, 2015 Share Posted March 21, 2015 I know nothing at all about cars so wanting some advice, I have a Vauxhall Astra 1.3 cdti and we have been to Chester zoo today and back and got home turned the car fully off and the car fan is still going and we have been back a good few hours now! What could this be? ---------- Post added 21-03-2015 at 23:31 ---------- Must add it is still going off !! Link to comment Share on other sites More sharing options...
1960boy Posted March 21, 2015 Share Posted March 21, 2015 Quite normal, not to worry. Link to comment Share on other sites More sharing options...
Eater Sundae Posted March 22, 2015 Share Posted March 22, 2015 (edited) Quite normal, not to worry. I wouldn't expect it to carry on for several hours, though. I would have thought it would have cooled the engine within a few minutes and then switched off. I'm not familiar with the detail of these. Hopefully someone will be along soon with some specific knowledge. Meanwhile, I would assume there is a thermostat which switches the fan on if the water temperature is getting too high, and off when the temperature has dropped to an acceptable level. In this case, I presume that the thermostat is sticking in the "on" position. Edited March 22, 2015 by Eater Sundae Link to comment Share on other sites More sharing options...
biotechpete Posted March 22, 2015 Share Posted March 22, 2015 Quite normal, not to worry. Not if it's been going a few hours it's not. OP you could try turning the ignition on to see whether the engine temperature is still high. Might be an electrical fault or it might be a coolant problem.

tonymar Posted March 22, 2015 Share Posted March 22, 2015 (edited) Probably a fault with the temperature sensor that operates the cooling fan Or it could be the wafle valve not engaging with main big end sprocket I think Edited March 22, 2015 by tonymar Link to comment Share on other sites More sharing options...

These are very specific symptoms and it's one of those rare occasions you can listen to an educated and experienced guess. Most likely the coolant temp sensor (or at least one of them, if yours has more than one). Much less likely causes (and more expensive) would be a wiring or ECU fault. ---------- Post added 22-03-2015 at 00:32 ---------- Probably a fault with the temperature sensor that operates the cooling fan Beat me to it Link to comment Share on other sites More sharing options...
