Low coolant causes this. Check coolant level again. System needs to have air pockets burped out of it.

Radiator full. Top hose never got hard or hot. I can squeeze too hose and hear fluid move in radiator. Thought if thermostat stuck it would've been hard.


How would I get any air out?


When engine cools back off remove the radiator cap. You will probably find that it's low again. Add needed coolant then start engine back up. Carefully watch the level in the open cap of the radiator. As it drops add more coolant. Some times squeezing the top hose will help speed up this process.


I give that a try tomorrow. Didn't know if overheating the engine may have affected the thermostat. Just confused why it didnt seem to take any coolent through the engine. Maybe I put cap on to soon?


Starting it up with cap removed completely seemed to work. Not sure if there was a lil ice built up somewhere or just air in system but heater is working and not overheating no


That's great. Glad you got it.


Thanks. Will take around town today and see what happens before I hit interstate with it. Anybody considering water pump on their own . It's not hard at all. 3rd dodge I've done and newest actually the easiest.
