Hi there. Question i cant find an answer for - (Nissan navara d40 st-x 2007 yd25 spain built. Diesel. manual.) The secondary fan attached to the radiator behind the clutch fan... heard it called by these names- the thermo fan/ electric fan / A/C condenser fan...
Its not engaging or working at all. Done a starter test (where u turn ignition on/off pump pedal so many times etc) it did turn on and run the low and high speeds. So i am wondering where the fault may be. I was told to replace the entire fan, yet i was wondering what actually causes it to engage. A pressure or temp sensor? I read they are to kick in when air conditioning is running or above a certain temp. Which it doesnt.I was told there is a resistor on the electric fan that must be faulty. Does anyone know? Or Could this b a relay problem? Dont want to replace the fan and find its a fault elsewhere.
Its stinking hot in Australia thru summer and feel its neccessary to have this fan functioning like it should.
The plastic bleeder join along the heater hose blew and lost water. Noticed as passenger the aircon not working, leant over to see gauge on high/ engine overheating.
Head warped, had it shaved back and replaced. Thermostat replaced. Chemically flushed out the radiator and Bled the air out of the cooling system as gud as cud be.
Still over heating under any work like going up any incline especially if aircon is on. Ordered a new radiator as we used stopleak in it after the overheating and before head was tested and shaved back. It sat for awhile during the head repairs so it definitely prob blocked up some. Also ordering a new clutch fan. Hopefully the new radiator and clutch fan coming will resolve the overheating but just lost with this little fan and it not engaging which may have been the initial source to all the problems if not just the blown plastic bleeder part.
Doesnt seem to b a lot of info on this. Read the manual part but electrical stuff is over my head... brrt.
Please help or inform me before i order a new thermo fan.
Thanks. Kelly.
