Hopefully i can help..
What model Peugeot / engine size / year - do you have?
Hi..there thanks for your reply
Ok.if the car was "actually" overheating then coolant in the tank would be boiling or rumbling or in some case will force it way out if it where headgasket problems usually caused by either a problem with the coolant system in regards XXXXX XXXXX failed thermostat/water pump.. By the sounds of your fault I don't think you have whats termed as common overheating issue as above,but that could be verified by using heat sensing gun - if the temp registers overheating as soon as the key is turned or basically on cold engine - there is chance this is more of an electrical fault ie:- temperature sender unit fault giving/sending out incorrect readings which in turns makes out the engine is overheating "which it isn't really" and thus kicks the fan in .they would need to test for that.so as above if thats whats happening and doesnt happen once the engines upto temp etc certainly try that sensor it will be usually located on the thermostat housing with a green plug body..sometimes you can point a heat sensing gun like mentioned before at the engine cylinderhead and see if the temp reading on that matches what it currently saying on the dash or when plugged upto a diagnostic machine..if the temp is incorrect then it most likely a temp sender issue.I do hope this help
