Paytonsforit91109 Posted March 21, 2015 Author Share Posted March 21, 2015 Thank you. In the very limited time I've been on here, I've noticed the willingness to help and welcome. It's great to find people that are still willing to help each other out. That's not nearly as common as it used to be... Another rookie question, my truck has the air operated radiator shutters. There's a valve to keep them open or closed. Now, when closed... Are they controlled by the thermostat to open, or are they simply closed Quote Link to comment Share on other sites More sharing options...
Mack man 1973 Posted March 21, 2015 Share Posted March 21, 2015 There is a thermostatic switch that controls them they are air and electric controlled my v8 has a switch in the water manifold that signals the air sitter valve to open and close Quote Link to comment Share on other sites More sharing options...
