2001 Chrysler PT Cruiser Question: heater core flush/replacement?
Heater cores can sometimes be flushed with success if they are getting clogged: PERFORM THIS PROCEDURE AT YOUR OWN RISK* 1. Remove heater hoses from core or disconnect the other ends of the hoses. 2. Flush in both directions with a garden hose and compressed air pressure. 3. Replace coolant and bleed air from cooling system. *IMPORTANT NOTE: It is theoretically possible to burst the heater core if it is severely clogged. Although if this happens you can bypass the core by connecting the two hoses together and you can still drive the car with no heat until you replace the core. I have flushed dozens of heater cores and have never had one break (even ones that would not flow anything initially). Good luck. James - Jamesw
