    Hi all, I think my thermostat has broke as my engine temperature rises towards 120c when stationary. If i start to drive it comes back towards 90 even quicker if i put the heaters on max. What I'm trying to find out is it easy to get to as I have no clue where it is, and can I replace the thermostat myself or is it a dealer/garage only job. Thanks Chris:sos:

    More likely waterpump failiure tbh. The plastic impeller breaks away from the metal shaft.

    However its a bit of a job to change depending on the engine

    Normal symptoms of the thermostat at fault is if your temp isn't getting up to 90. If its going past 90 and overheating like you say then it'll be the water pump like Mark said.

    Arete electric fans still working when you switch the aircon on?

    Maybe a fuse gone then as the aircon and the temp are only connected as far as i can see by the fans

    Thanks, I will check that. Is the fuse in the side of the dash or under the bonnet and I hope it is that as I have had a cam belt change and had the plastic water pump changed for the metal one.

    IIRC the fan fuse is in the car fuse box. For continuity, chech the ones on top of the battery anway, will take seconds.
