Fan switch?

So I have been having overheating issues (sorry to bring up a dead horse topic). I decided to replace the fan switch before I go the clutch route. I locate the fan switch to remove it and there is nothing plugged into it, just the 2 prongs sticking out??? Guess I found my problem... What should be connected and where would I find it?

Thanks guys!

Thanks Jimmy, but this is not an electric fan, it is the stock unit. The "switch" I am referring to is the brass plug with the 2 prongs that threads into the rad hose. Should there be anything attached to it?

Are you talking about a swich for the A/C fan or an aftermarket radiator fan?

The A/C fan doesnt really affect engine cooling. Several people though have wired the fan to run on a manual overide switch to help overheating without having to run the A/C compressor.

Before investing in a new fan cluch I would look at the electric radiator fan like the flexlite solution in the previous post. It has worked very well for me. There is good info on this board if you search 'flexalite'. Plus they have a new twin high output 'puller' model this year - #280 or 290 I think.

The 'switch in the photo is to be connected to the A/C circuit. Again it wont have any effect on your overheating.

Ah, thanks Owen. No A/C for me, so that it the reason for the bare switch.

Thanks

Our Buick aluminum V8 is prone to overheat especially at lower speeds and low revs when there is little airflow. Before spending money read the theads on this board and do inexpensive things first like backwashing the radiator gills, coolant flush, thermostat change etc.

I mainly use the D offroad with low speeds and revs. In the end I opted to go the Flexalite route and havnt looked back since.

Best!
