Where is the cooling fan switch on a 350 TPI car? I have been told it is somewhere below the right head, but I can´t find it.

I need to change to a cooler switch, here we got 40ēC easily, and the car tends to overheat all the time,which is not funny at all.

I got two senders (at least they looks like) at the front on the TPI intake. On is the coolant temp sensor. The one with the yellow wire if I am not wrong. So: What is the other one?

Please help.

 

The coolant fan switch is located in the passenger side head
just below and between the two rearmost (6 & 8) sparkplugs. It has one wire on it, you have to squeeze the connector to remove it.

The front of the intake manifold, coolant temp sensor on left, cold start injector sensor on right, I could be wrong about the second one, but I'm pretty sure.

 

Thank you John, they both looked about the same to me.

Does anyone know the GM part number for the CTS?
Will be handy to know.

 

GM P/N? No.

Borg Warner P/N:
TFS-1 stock switch
TFS-8 cooler GN switch

Of course, I could have mixed up those numbers.

 

if your going to change the coolant temp switch you might as well buy a little lower turn on temp..
