I have an 86 TA with the single fan. I am running a 180 thermostat. I would like to change the fan switch to one that turns the fan on at 200 and off around 185.
I know I could spend $40 on a hypertech, but I was hoping to find a part readily available at a local parts store.
I found a thread listing some Advance auto GP Sorensen numbers, but they are no longer good numbers from advance.
Thanks!

 

Just use one of these.You can even wire in a toggle switch that allows you to turn the fan off when running or off before it starts running. The switch is temperature controlled and is adjustable so you can set it where you want.Its also very simple to wire in.

Here's the diagram. It does use a probe.

 

Also this switch can be found at Autozone under # 4028.
