Guest Taylrl Posted May 22, 2016 Share Posted May 22, 2016 Hi, I've recently bought a mk 4 cab and have been noticing that the temperature dial starts to rise quite high (it's even been I to the red once) after a little while when I'm doing short trips around town, stopping at lights etc. If I get onto a dual carriage way it seems to stay level and maybe cool a bit. I start to see this after about 20mins of stop/start driving. Any ideas? Cheers Link to comment Share on other sites More sharing options...
jinks Posted May 22, 2016 Share Posted May 22, 2016 check if your cooling fan is coming on Link to comment Share on other sites More sharing options...
Ian71 Posted May 22, 2016 Share Posted May 22, 2016 Cvh engines do run hot m8, make sure your coolant level is ok and fan cuts in ok, but you have to get used to it. What I have done is to wire a switch to the fan so if fan does not come on I can switch it on manually. Link to comment Share on other sites More sharing options...
Stephen Bearded Minky Hill Posted May 22, 2016 Share Posted May 22, 2016 I now have an alloy radiator and an 82 degree thermostat with a curved blade fan as mine used to get hot. Not now. Link to comment Share on other sites More sharing options...
Paul Grainger Posted June 18, 2016 Share Posted June 18, 2016 The switch for the fan is the big two wire one in the thermostat housing. Most likely is that it is faulty and not switching the fan on. If the fan is not working when the engine is too hot disconnect this switch and short across the wires with a piece of wire. If the fan runs then the switch is faulty. Cheap and easy to replace as it just unscrews but do it with the engine cold. The mk 4 also has two black wires near the strut mount on the drivers side inner wing. They just poke out of the loom and do nothing! Connect them together and the fan should run. If not the fan could be faulty. Good luck Link to comment Share on other sites More sharing options...
