Thread: Heater core

Hybrid View

  1. #1

    Default Heater core

    What can I use to flush out just the heater core with out contamiting the cooling system

    You can use water. Disconnect the two hoses that carry coolant into and out of the heater core. This will ensure you do not contaminate the rest of the cooling system. Hope this helps
