Detailed Description

Spectra Premium HVAC heater cores are manufactured with attention to fit, thermal performance, and consistency.

Use part number 94612 when searching for a replacement heater core for 1982-1984 Buick Skyhawk, 1982-1984 Chevrolet Cavalier, 1982-1984 Oldsmobile Firenza, and 1982-1984 Pontiac J2000/J2000 Sunbird applications without air conditioning.

What It Helps Address

  • Weak or inconsistent cabin heat
  • Coolant seepage from a failing heater core
  • Fogged windows caused by poor defrost output
  • Restricted coolant flow through the heater circuit
  • Heat loss in select Buick, Chevrolet, Oldsmobile, and Pontiac compact cars

Installation Notes and Tips

Verify vehicle equipment before ordering, especially air conditioning configuration, since this heater core is listed for select models lacking A/C. Compare the original core dimensions and hose connections during removal, and inspect the cooling system for contamination or leaks before installing the replacement. Proper coolant refill and air bleeding are important after service.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control are used to produce heater cores that meet or exceed original equipment performance for the applications they replace.
