Faulty thermostatic switch?

Hi all

Everything seems to be ok with my recently MOTd little car except for one thing - the engine fan does not come on when the temperature exceeds normal running temperature. I was stuck in traffic this morning running at 110 when I decided to turn around and go back home - the car quickly cooled down to between 70 / 90 when moving. In fact the car rarely reaches 90 and seems to be happy (even on long journeys) at around 70 - does this sound ok or is the thermostat faulty? Should it run 'hotter' in normal use?

The fan works as I have connected it straight to the battery - any ideas re. fixing this? (parts, cost etc.) I am looking to avoid fitting a switch to manually put the cooling fan on (but will do so if I cannot fix it as I don't fancy being stuck in traffic in the summer with no way to cool the engine down).

Would appreciate you educated advices!

Re: Faulty thermostatic switch?

unplug the switch, ignition on and then bridge the connections on the wire you've unplugged. the fan should spin. if it does, faulty swtich. if it doesn't check the fan fuse, and wiring.

Lloydtyphoon, how much did you pay for a new switch? Is the 769 FIRE switch the same as a 999 FIRE switch? Or do you mean that you wired a seperate switch off the battery?

Re: Faulty thermostatic switch?

Many apologies....yes I have one, but.......one question to anyone that knows. The switch on my current panda the wiring part is in the middle but this one is to one side. I can't for the life of me think that it won't work exactly the same but why the difference in shape?

BTW I'll send off in the morning.

Yes, it did solve the problem. Thats the reason my car has an emission failure on its test sheet! It didnt actually fail the emissions, just started overheating whilst he was about to do it, so he didnt feel safe to continue!
