Abbie1994 Posted April 18, 2015 Share Posted April 18, 2015 Hello How do you check the engine tempture sensor is working , I have no engine management light on but my fan has stopped working I have had a new water pump and thermostat fitting but still no change.

Dan62 Posted April 18, 2015 Share Posted April 18, 2015 It might sound a bit obvious but does the temperature gauge on the instrument cluster work ? If the gauge is working, the sensor is ok, the system has a fail safe so should the sensor fail (or you disconnect the sensor) the fan will run continuously. If the gauge works but the fan fails to run possible reasons are; The cooling fan relay in the central fusebox. The fuse in the battery junction box The fan itself.

Abbie1994 Posted April 18, 2015 Author Share Posted April 18, 2015 The gauge works , I have checked the fuses behind the glove box there ok , have wired the fan to the battery and it runs , haven't checked the fuse in the battery junction box were is this located Quote Link to comment Share on other sites More sharing options...
Dan62 Posted April 18, 2015 Share Posted April 18, 2015 The battery fuses are attached to the the positive battery terminal connector. Its fuse FD 40A. More likely to be the relay K45 if the fan works. Quote Link to comment Share on other sites More sharing options...

Dan62 Posted April 18, 2015 Share Posted April 18, 2015 It makes no difference for you, if you had an early mk6 with Ac there would be an extra relay and resistor in the circuit. Quote Link to comment Share on other sites More sharing options...

Dan62 Posted April 18, 2015 Share Posted April 18, 2015 follow the short red wire from the positive battery terminal, it goes to the fusebox Quote Link to comment Share on other sites More sharing options...
Abbie1994 Posted April 18, 2015 Author Share Posted April 18, 2015 How can I check if the fuse is ok or do I need to get a new one Quote Link to comment Share on other sites More sharing options...
Dan62 Posted April 18, 2015 Share Posted April 18, 2015 The fuse is probably good, more likely to be the relay. Check fuses with a multimeter. Quote Link to comment Share on other sites More sharing options...
