Can someone please explain how the OEM fans should be wired?

Is it live to the fans > fans to the switch > switch back to the fans

and obviously when the temp rises the switch opens and makes the circuit????

Or is it a 2 stage switch?? Does it go to a relay??

I could do with seeing a proper diagram really.....


At somepoint my cars had a manual switch wired in which im trying to remove, but its a headache working out what other people have done??

 

there are two relays behind the battery, the fan switch has a switched earth and a switched live from the fan switch to turn the relays on...

this may help,

There ARE 2 relays behind the battery. One is Fan and the other heated screen. The fans on an Escort Cosworth are speed controlled by the 5 pin switch in the radiator. I have ford drawings if you need em.

 

Can you send them to me ??



Dennis, that link doesnt work???

 

Are there 5 pins? I recall that mine only had 4 pins... 2 big and 2 small or am i being thick as usual

 

im pretty sure there are 5 , row of 3 and 2

 

My final answer is still 4... The only way I remember is because the multi plug broke off mine so I had to work out what pins were what... knowing me im talking about a different plug. It was the one that screwed into bottom of radiator. I dont know much about cars so I wouldnt listen to me really

Im dreading the underbody clean up haha.

 

ive just been to check,lol, you are correct 4 only

 

bloody nora...Im right about something for once.
