that dreaded radiator fan resistor

 

im a fiat and ford fan but i bought a xsara picasso after my last modded fiat punto died as a stop gap tbh not a bad car but with faults...

 

laquer peeling.... no probs but its an 07 plate and it had 12 months mot so paint isnt a problem

 

firstly when i hit the road i found the usual  crappy running and then the radiator fan failed to work as the weather got warmer...

 

i plugged in my digital data port reader and no faults but still run rough and when hot it would stall......

 

firstly do your homework when buying french as the car if neglected will fail. the mpg was lousy so new maf sensor £14 and running good but stalling.

 

i read a few stories onnthe matter in hand to find that although the cooling system is a bit hap hazzard if not maintained it also has a non self destruct mech built in . the obd reader shows no faults but hit three bars onbthe temp guage and the stall follows. the system its self is fused powered and set up with relays and a heap of wiring all leading to the ecu. the wiring its self is quite simple but add realays the fan the fan resistor in the front of the radiator. most problems generally sorted by changing the radiator fan resistor cost £13 and conector lean hey presto problem solved . dont think for a minute that taking the bumper off is the only way it can be done it took me 1 h 30 mins to fix. undo the lights top panel bonnet catch top bumper screws and you can test the fan and the resistor can be removed and replaced . dont waste time cleaning take it out and sling it away. providing the fan temp sensor and relays work test the fuses replace the resistor and it all ok . when done ive driven for three hours 30 miles on a warm day and no probs .
