Cooling Fan

[Guest vinnie_b23]

Hello peeps,

Im havin a problem getting my cooling fan to kick in. Can anybody tell me where the temp gauge should be when the fan should turn on. I ran it upto the 2nd thick white line and it still didnt start.

When i disconnected the fan switch in the radiator and bridged the power (green) to the middle wired, as there are three, the fan started

Does this mean dodgy fan thermostat switch, or resistor, or something else?

 

Also there was a loose connector coming off the fan thermostat switch with the exact same wires replicated, when i bridged these the fan started too.

 

Any help or ideas?

Ok thanks guys, narrowed it down to the fan switch in the ran. Is this a common fault then?

Didnt realise they were two speed. Can anybody tell me at what temp the 1st and 2nd staged kick in on the gauge.

Thanks

Yeah they pack up and prevent the fan kicking in. The guage is a best guess. Mine would kick in just over the third thick white bar (just over 90ºC ish).

 

The brown plug you mentioned earlier is there to test the fan.

Great, so the connector isnt needed. There is a few loose ends on the car because the previous owner went crazy trying to remove an alarm system so im just trying to come to grips with what goes where.

Thanks guys

Replace like with like.

 

The temp operating range is stamped into the body of the switch usually, or it's indicated by a coloured plastic band.

 

Here's a link to the range of switches, and is in a resource you'd benefit greatly from learning how to use. It's brilliant!

 

You should state what car/year it's for too when you have a problem.

 

Rad fan switches

 

You want item 5. To get to the main menu to look up other items just end the web address at "pug/".

 

These come from ECP, GSF and naturally main stealers.
