Detailed Description

The One Stop Solutions 98535 heater core is engineered for classic GM and Pontiac vehicles with air conditioning systems, including applications such as the Buick Skylark, Chevrolet El Camino, Chevrolet Monte Carlo, Oldsmobile Cutlass, Pontiac GTO, and Pontiac LeMans. It is also listed for Chevrolet Bel Air, Caprice, and Impala W/AC, along with Pontiac Bonneville, Catalina, and Tempest applications. This part cross-references Spectra Premium 94535 and 398226 for the same application.

As an aluminum HVAC heater core, 98535 is designed to replace copper-style originals while maintaining OE-style fit and function. The construction and testing focus on durability, leak resistance, and long-term service in vehicles that have accumulated mileage.

What It Helps Address

• Coolant leaks from a failing heater core
• Reduced cabin heat output
• Internal corrosion in aging copper-style cores
• Premature failure from vibration and thermal cycling
• Fitment issues caused by non-OE replacement dimensions

Installation Notes

Verify the vehicle’s HVAC configuration before ordering, since listed applications are for vehicles with air conditioning systems or W/AC. Confirm the original heater core style and compare the part number, dimensions, and hose connections before installation. Replace any degraded foam or seals during service to help maintain proper airflow through the HVAC case.

Quality Assurance

Each One Stop Solutions heater core is individually pressure tested and validated with cycle, vibration, burst, and environmental testing. The aluminum design and plated tubes are selected to improve service life in demanding HVAC use.
