Electric Fan not working.
Hi Guys....from my post a couple of weeks back re overheating and the fan blade thats come off...well I have put it all back together now and tested the electric fan, it works ok.
But now I need to get it going when the engine gets hot because it does not kick in...which could be the problem of the overheating So its going to be some sort of electric/senor fault.. Can you suggest where to start... what would be the best part to replace first. Thanks Bill waiting for my second jab. |

Let's see if we can make sure that you only have to buy one part, the right one! To do this we need to gather information and do some thinking. You say that your fan does not run when the engine gets hot. What is "hot"? Your fan should not trigger until the coolant reaches 104˚C. Have you activated the instrument pack digital temperature display to see if your engine is achieving that temperature? How did you test the fan? Have you carried out the "demist test"? Simon

Electric fan
Yes carried out a demister test fan motor works fine...and no I have not checked the temp yet on the gauge.
But because the car is now on sorn I can only run it on my drive even so after about 20 mins and dont forget the car is stationery I would have thought the fan would come on like in heavy traffic,,,,It was working up to about 4 months ago. The other issue I dont understand is the water pipes around the engine seem to be hot...but when I take the water cap off ( I know slowly) the water in the reservoir is only luke warm... lastly...what sensors would you suggest I need to replace can you name them Thanks Bill |

Fan not working
Hello T Cut I find your posts very informative...so could I ask you another question regarding this problem. The fan blades came away from the spindle so obviously the fan was not working..after a great effect I have manged to put back on again securing with a screw and some glue...
The motor works in the demisting mode...but I am trying to find out why the fan does not come on..it used but stop which I think is causing the over heating problem So heres the question......People on here have said it could be the resistor in the fan housing a sliver type...which could mean taking the whole front off again, I really dont want to do this. Do you think it could be the resistor as the motor works ?? or should I be looking elsewhere If I do need to replace could i fit between the blades without taking the fan off again.?? Any advise would be gratefully received. Thanks Bill |

There's no need to worry, it won't. An idling engine isn't under load so produces far less heat than when it is propelling the car. I see no evidence that there's anything wrong with your cooling system. You say that the "demist" test is positive so there cannot be anything wrong with your silver resistor. There's absolutely no need to take off the bumper again. Your previous overheating problem would have been caused by the fan blades being detached from the motor. Now that you have repaired that, you should expect no further trouble. Simon

HI Bill
If the silver or when it fails which it will one day, change it for a gold one, you can fit it between the blades of the fan as a couple of sections are larger than the others. https://www.the75andztclub.co.uk/for...d.php?t=216734

Electric fan not working
Hi Guys....here is the latest with this fan problem
I took the car out for a little drive before I did I disconnect the temp sensor clean it and left it unconnected....started the car and the fan kicked straight away. So I am confident for the time being its not the sensor on the fan housing. would this be right ?? Drove for about 1/2 an hour temp gauge shown half way can I assume by this that the car is not overheating. ?? However for some reason the electric fan is not kicking in it normally does if the car is stationary for a time. Could you advise how I can check or to get it working.. Thanks Bill |
