spud1962 Posted August 25, 2012 Share Posted August 25, 2012 Please can anyone help? Just lost the use of radiator cooling fan on my mk6 1.8 16v escort ghia, causing the engine to overheat. I think i have discovered the correct sensor/switch connected to a coolant pipe underneath a short right angled air intake pipe which i have temporarily removed Does anyone know how to test or bypass the temperature switch at the source? How should I test if the fan itself is not kaput? When disconnected from the switch, The loom end has 4 wires. The terminals are marked 1 to 5 with no connection to terminal 2. if i bridge the switch at this point, surely this will activate the fan? Not sure how to discover which of the connections when bridged will allow the fan to operate. Note: If I disconnect the switch and run the engine - the fan does not operate either, but I'm not sure if it should anyway ? Quote Link to comment Share on other sites More sharing options...
oilburner79 Posted August 25, 2012 Share Posted August 25, 2012 You need to bridge the fan switch it's usually located on the radiator Quote Link to comment Share on other sites More sharing options...
spud1962 Posted August 25, 2012 Author Share Posted August 25, 2012 Yes, true, a lot of cars do - but i think the switch is located elsewhere (see above) Quote Link to comment Share on other sites More sharing options...
