Comments about CARQUEST Heater Core:

The oem part is made of copper. This one is made of aluminum. The flange or flared ends are bigger and thicker than the oem part that is whhy it's very hard to install. The locking clip would not go in and the hole of the pipes are a bit smaller that the oem part. That's why I ended up using two hose clamps rather than the oem clips and use a high temp RTV silicone gasket to seal the pipes from leaking.

  • Q:

    What metals, exactly, are used in this heater core? The description is extremely vague about that. It says "long-life alloys". Is it aluminum, brass, copper, steel?
