Topic: Thermo switches

[nate650]

I have an 85 with 22r and one of the wires that goes to my thermo switches broke off at the switch. What do these switches do? will it hurt my gas milage if I leave it unconnected?

solder a female connector on and go.  Or go to PnP, get a stock connector, splice and heat shrink it.

they are to tell the vehicle what temperatiure the coolant is at.....

is your truck efi if so one is the cold start timer switch for the efi,and the other should be your temp sender.when looking at the front of the block they are below the intake manifold ..then if so the right one is temp sender the left is thermo switch for efi cold start timer ..
