My girlfriend commented that she wasn't getting hot air from the heater. I didn't ask what the coolant temp gauge was reading. I swapped out thermostats with a 190* Murry brand from O'Reilly Auto. I took the truck out for a test drive and noticed the coolant temp runs between the mark above 130* (150*?) and 210*. This was with a piece of cardboard covering 1/2 of the radiator . I didn't grab my infared heat gun to take with me. Leaving from stop or accelerating after a turn, the vents will blow pretty hot air. At a constant speed, the air from the vents cools off a little. I checked heater hoses and notice one hose I can't keep my hand on very long. The other hose is a tad bit cooler. I'm thinking the heater core is circulating. I have heard that aftermarket thermostats for the V-10 engines are not very good and I needed to install a $100 Mopar thermostat. Any ideas what my next step should be? Thanks for your help.
