One Stop Solutions 98607 HVAC Heater Core

OE-Style Heater Core for S10 and S15 Applications

One Stop Solutions part 98607 is a premium aluminum HVAC heater core built to match original equipment form and function. It is a direct replacement for copper-designed heater cores and is engineered for Chevrolet S10, S10 Blazer, GMC S15, S15 Jimmy, Sonoma, Jimmy, and Oldsmobile Bravada applications without air conditioning.

This heater core uses cadmium-plated tubes inside and out to help resist premature failure, and each unit is pressure tested before release. The included foam and accessories support a cleaner OE-style replacement during service.

Key Features

• Drop-in fit, form, and function for OE-style replacement
• Premium grade aluminum construction for added durability
• Cadmium-plated tubes inside and out to help reduce early failure
• Individually pressure tested for leak verification
• Includes necessary foam and accessories
• Built to address common original design weaknesses in high-mileage vehicles

Detailed Product Description

Part number 98607 is designed for drivers servicing older compact truck and SUV HVAC systems that need a reliable heater core replacement. It is compatible with 1982-1994 Chevrolet S10, 1983-1994 Chevrolet S10 Blazer, 1982-1990 GMC S15, 1983-1991 GMC S15 Jimmy, 1991-1994 GMC Sonoma, 1992-1994 GMC Jimmy, and 1991-1994 Oldsmobile Bravada, all without AC. This makes 98607 a practical choice when restoring cabin heat performance in vehicles that commonly see age-related cooling and heating system wear.

This part cross-references Remy 94607 and 399052 for the same application.

Common Issues This Part Can Address

• Weak or inconsistent cabin heat
• Coolant leakage from a failing heater core
• Restricted heat transfer from corroded internal passages
• Fitment problems caused by worn original components
• Repeat failures in high-mileage HVAC systems

Installation Notes and Tips

Verify vehicle configuration before ordering: this heater core is for w/o AC applications only. Confirm the existing core dimensions, hose routing, and HVAC case layout against the removed part before installation. Because heater core replacement often requires access to the HVAC case, inspect related seals, hoses, and coolant condition during service.

Quality Assurance

OSC Premium heater cores are manufactured from aluminum, pressure tested individually, and built with cycle, vibration, burst, and environmental testing in the validation process. The design follows OE-style form and function while using materials selected to improve service life in older Chevrolet S10 and GMC S15 platform vehicles.
