I have a 93' Cheyenne and I am trying to figure out what is wrong with my heater. I recently replaced my radiator, heater core, thermostat, as well as the heater hoses. I had heat the day I made the fixes but I haven't had heat since. Also, I notice that my truck runs below the temperature that it used to run before (new temp=150* vs old temp =210*). All the hoses are warm. Any suggestions?

make sure you get all the air out of the system. I think those old Chevys had air bleeder valves.

You have to completely burp the system to get all the air pockets out.
