char44 Posted May 14, 2014 Share Posted May 14, 2014 Hi don't know if anyone can help, I have an 04 plate 1.4l petrol fiesta lx. It has started overheating when stuck in traffic or sat on the drive running. The temp gauge in the dash doesn't increase (reads normal temp all the time) and the first thing u know about it is steam coming out of the bonnet from the coolant reservoir. It's been in the garage and they can't get to the bottom of it! The fan isn't kicking in when it should. It has had a new sensor put in and isn't the fuses and relay they are working fine. The fan does work as when the mechanic ran a diagnostic test and it worked. This only happens when the car is sat idling. Has anyone experienced this before and if so can you help!? The mechanic is stumped at present and only suggestion is to send the ecu off to be tested. Quote Link to comment Share on other sites More sharing options...
MattDRX Posted May 14, 2014 Share Posted May 14, 2014 If the temp gauge isn't budging I'd be changing the thermostat first and foremost and from there the water pump, does it make any funny or horrible noises when the engine first turns over?

char44 Posted May 14, 2014 Author Share Posted May 14, 2014 No funny noises at all. I will check with the mechanic re changing the thermostat but I'm hoping he woulda of already checked that as it is a pretty obvious thing to do! When you check in the coolant tank when it is running you can see the coolant being pumped round fine. Quote Link to comment Share on other sites More sharing options...
