$61 bin cooling fan issue

I've been driving this car and it begins to get hot with a/c on, city driving. On the highway, it stays cool. I'm going to give the car a flush, replace the single fan and wanted to replace the thermostat with a 160. Was looking at the $61 and couldn't find where to kick the fans on earlier. Am I using the wrong bin?

Re: $61 bin cooling fan issue

The '8746 $61 mask doesn't control the fan.

There is a switch in the passenger head between 6 & 8. Along with the A/C pressure switch. Can replace the head switch with one from an '87 Buick GN. It turns on at a lower temperature.

Couple of things to check: make sure that the air dam is intact. Remove upper radiator mount and check area between A/C condenser and radiator. That area usually fills with road debris which cuts off the flow of air.

Those fan switches are really easy to snap off at the bolt face if you're not careful
