right got an RS Turbo converted cab,as far as i can see standard apart from stainless exhaust system,dirty dump valve,and incar boost controller

anyways,they guy who i had it off had by passed the heater matrix,due to when the converison took place one of the pies tot he heater matrix had been damaged,so i got it home drove fine all the way home with out fault no over heating,(drove it over 14 miles home)took it out the next evening,got stuck in a little traffic and i could see the needle rising up,so was getting very worried by this point,drove it straight home and switched it off,
thought there might have been an air block in the cooling system so ran it up to see if there wat any air trapped,it was just above running temp and the header tank started bubbling up badly and started to over heat badly too,the fan isnt cutting in either

theres no oil/water mix is it the headgasket?failed water pump?cracked cylinderhead?wot should i look for?

is it a big job to do myself?exspensive?

any advice appreciated

cheers Jez

then its a fan problem as you stated, check the wiring plugs on the switch, just below the top hose/thermostat housing if it is unplug it and bridge the wires the fan should come on with ign on if it does then you have a faulty temp switch, if it dont come on you need to check the wiring to the fan or maybe the fan its self, i would say the switch 90% of the time.

try to bridge the multi plug on the fan switch on the thermostat housing and the fan should come on mate!
if they do it the switch, if they dont its poss wiring!

can i make something so i can run the fan permantly?as my old ERST used to suffer bad with over heating too nothin like this though

jonnyrsturbo

there is two connectors half way up the o/s wing if u connect them then it should run constant, or perm bridge the multi plug on the thermo housing....

or put in a switch!!!!!!!
