Guest Posted August 26, 2008 Share Posted August 26, 2008 it could be the thermostat as well is sticking closed especially if it does it in a quick space of time or the fan sender unit is not working .. try locating this and bypass the two wires that are attached ( connect them together with the ignition switched on and see if the fan works then ) and as above check fuse .....and otherwise to ascertain that the fan is working so try to work out which is the power supply cable for it ( +ve ) and add a direct feed to that from battery to test BUT make sure that you have the +ve side not -ve otherwise arc welding r us if that dont work leave the +ve supply fixed on and add an earth feed (-ve) if after these tests the fan still fails you know its likely a new fan is requiredhave you tried to turn the fan blades manually ( with no power turned on or on a hot engine) to see if they actually turn ?

flipper Posted August 26, 2008 Share Posted August 26, 2008 could be the seal in the pressure cap on the radiator isn't sealing. lower pressure = lower boiling point. Quote Link to comment Share on other sites More sharing options...
handyandy24 Posted August 28, 2008 Author Share Posted August 28, 2008 would the fan not operating make the coolant boil? if not. looks like i have a prob with my coolant system as well as the fan. plenty to do this winter ffs lol Quote Link to comment Share on other sites More sharing options...
