Hi KC2KALI, welcome to the mightyram. Sounds like you might be in need of a new thermostat (symptoms are pointing towards it being stuck open). It's funny how an engine can sometimes run cold even when driving it just because the outside temp is low. I had a car that I'd done an engine swap on it that ran cold enough in peak winter for it to almost stall out (I would have to pull over and let it idle for a few minutes so the thing could get back up to operating temp! I ended up jamming an offcut of corrflute in front of it to block some airflow into the radiator)
the 1983 had the same issue...choke was on way too long...after driving for over an our still cold in cab. previous owner installed thermostat upside down!
much thanks guys. replaced thermo,gasket,and housing..en everything is good now..works like new.
upside down?????dont even wanna kno lmao
