techbod Posted August 8, 2008 Share Posted August 8, 2008 any work been done on the cooling system? have the wires been joined to make it run all the time because the temp sensor wasn't working? or simply a wiring fault and the fan is live all the time Quote Link to comment Share on other sites More sharing options...
Guest Alan2008 Posted August 8, 2008 Share Posted August 8, 2008 Its only just started doing it, I have cut the wire that feeds it for now so it does not come on at all. Quote Link to comment Share on other sites More sharing options...
techbod Posted August 8, 2008 Share Posted August 8, 2008 it sounds like the temp sensor/fan switch has failed, just cutting the wire will cause more harm because it will over heat Quote Link to comment Share on other sites More sharing options...
Guest Alan2008 Posted August 8, 2008 Share Posted August 8, 2008 Im not driving it at the moment since I cut the wire, could you tell me where the switch and sensor are please? Alan Quote Link to comment Share on other sites More sharing options...
techbod Posted August 8, 2008 Share Posted August 8, 2008 coolant temp sensor will be near the thermostat housing along with the fan switch but the switch could be on the radiator on the older cars, better to wire it up to a switched live so it only comes on then the ignition is on Quote Link to comment Share on other sites More sharing options...

Shemer Posted August 20, 2008 Share Posted August 20, 2008 Hi, Check the following site (it's for PUG306, but it should be the same cooling system (assuming you have original A/C). PUG306 cooling. See the cooling fan control unit in the pic. ? http://www.peugeotlogic.com/workshop/wshtml/electric/ac306/coolfan2/fan1.jpg I suspect it's the faulty one (the box is made by Italian Bitron, located either behind the glovebox (or, if no glovebox, under the plastic cover), or else - under the front driver's wing.
