Coolant issues.

I have a 2004 1.6 16v petrol C3. I have seen similair problems reported on here but need a bit of help. On startup, when the engine is cold, the dash lights up and beeps indicating an overheating problem and also the fan kicks in, obviously the engine isn't overheating and coolant level is fine. Once the engine starts to warm up, 5 or 10 minutes, all goes back to normal. Removed the air filter box and found a 'green' and a 'blue' sensor. The green had 2 wires coming from it and the blue only had one, is this correct ? Checked the ECU multiplugs and all is dry. Making an assumption that it's a sensor issue and am planning on replacing both. Does anyone know the part numbers of the sensors, and possibly suppliers who would be willing to post abroad ?

Hi ToeBat C3

Yes, blue and green sounds right for your car, one being a switch and the other a variable sensor.

Euro car parts will ship world wide, which would include 'abroad'. They also have a useful 'tool' for selecting the right parts from the year, fuel and specification of the car, if the UK registration number is not available.

micks garage also deliver across the world and have a similar search function to find parts based on the engine size, fuel, year, etc. This saves hunting down part numbers.

Thanks Arfur, will take a look.
