Check your pump

If the coolant in the ice box is hot im assuming the pump is running....but how often is it supposed to run is the question?Thanks

Wire it to run all the time. You should wire it so that it turns on in key position 2. Then you should see the fluid moving without having the car cranked. The fluid being hot is not exactly telling you a bunch about the pump. What pump are you running? Have you replaced it since owning the car?

i have changed it ...its the johnson pump...if i ewre it up to ignition it will be fine...

Wiring to ignition is good but won't solve the problem if the pump is act bad. I would also bleed the IC system to ensure there is not any air stuck in the system
