So i just changed my water pump. Did the thermostat while i'm at it and cleaned out the heater core with compressed air. I had no heat prior to changing the water pump(had to, car has 278 481KMs on it and original timing belt & water pump). Can a heater core go bad and is there a way to tell its done? Other than that, I don't know what else to look for.

 

Air in the cooling system will prevent you from getting heat. Did you bleed the air out of the system after the work you did?

 

Calab, sorry for my ignorance but how does one bleed the system? That never really crossed my mind.

 

This link should help you out...

Bleeding (purging) the Chrysler 2.2/2.5 liter cooling system

 

Calab, bleed the system. Still not heat. Next step: Heater core is done?

 

are both the hoses to the heater core as hot as the upper radiator hose when the engine is warm?

 

1 is the same as the upper rad hose(hot, cannot hold on to it for long). The 2nd one is just warm.

 

clogged heater core

 

Flushed it, still no heat (coolant is topped up and system bleeded). Now 1 of the 2 hose is cold, and other is blazing hot? Can it be the heater core is done?

 

yep I had said this a month ago
