  • [Corsa C 2000-2006] Overheating ,Fan sensor location

    Can anyone help .I have a corsa c design 1.2 with AC ,It Overheats and fan does not kick in .tried the AC and the fan works , I've checked other threads and they advised there was a fan sensor on the drivers side of the radiator near the bottom .I've looked everywhere and cannot find it .if anyone can point me in the right direction it would be appreciated

    The B model has the sensor in the rad. The C uses the signal from the coolant temperature sensor. When they fail then tend to fool the ECU into thinking the engine is cooler than it is which may account for your fan not operating when it should. The CTS is pretty cheap and easy to fit and it's a good idea to replace them periodically to keep fuel economy spot on. So for the price of a CTS I'd try a new one.

      Tried changing the coolant temperature sensor but still no good fan still did not kick in even though temp was in the red.

        Have you put a test wire to the fan to make sure it is actually working?

            Yes but if you bypass the existing loom between the cts and the ecu, and from the ecu to the fan, does work then?
