It drops in as a direct-fit replacement for a long list of 1967–1972 GM models, including the Buick Skylark, Chevrolet Chevelle and El Camino, Oldsmobile Cutlass, and Pontiac GTO and LeMans — see the Buyer's Guide tab for the full application list.

Little or no cabin heat, a sweet coolant smell inside the car, fogged windows, or coolant residue on the floor can be signs the heater core may need replacing.
