I was driving yesterday in sleet with an outside temp of about 32 degrees and the heater was not working real well (maybe because I have the cab that breathes?). The temp gauge was reading a full needle width below half which is about where it runs in the summer as well. I have not replaced or checked the thermostat since purchase, so I have no idea what temp it is or how old it is. I have replaced the heater, fan motor, and all hoses, but not the pump, and I have no problems with overheating in the summer. So my questions are; does anybody know what the approximate temps the marks on the gauge indicate, and how well does the heater work in your truck? And I have the standard recirculating fan heater type.
Thanks, Lee.
