Caution:
-
Vehicles are equipped with either an aluminum or a copper brass heater core. For all cases, replacement cores are copper brass. It is essential to
positively identify the type of core being replaced because there is a difference in the heater core to heater case seals (Fig. 18). Having the correct
seal is essential to the satisfactory performance of the heater system.
-
Identification can be made by looking at one of the core tubes after a hose has been removed. An aluminum core will have an aluminum colored
tube. A copper brass core will have a brass colored tube.
-
If the core has a copper brass core, the seal removed with the old core can be used with the new copper brass replacement core, proving it is not
damaged during removal.
-
If the core has an aluminum heater core, a new seal for the copper brass replacement core will be required.
