Well I need some ideas for making my heater blow hot air. Here's what I have. 1971 cj5 with 225 V6 freshly rebuilt. New aftermarket heater from Vintage air. 180 degree thermostat. Here in Wyoming it gets cold in the winter. On most days my jeep runs at 150* . I would prefer it to run between 180* and 190*. I do not want to block the airflow in front of the radiator if I can help it. I was thinking of trying a 195* thermostat or a 205*. Has anyone found a good fix for the say 0-30 degree weather.
