Detailed Description

OSC Premium heater cores are engineered for direct replacement in vehicles that originally used a copper-style core. Part Number 98045 follows the original equipment shape and function while using aluminum construction for the core assembly. The plated tubes are designed to help resist internal and external corrosion, and each unit is pressure tested before release. This makes it a practical choice for restoring cabin heat performance in 2002-2005 Ford Explorer, 2002-2006 Mercury Mountaineer, and 2003-2005 Lincoln Aviator front HVAC systems. It also fits 2006-2007 Ford Explorer front applications from 12/06.

This part cross-references Spectra Premium 93045 for the same application.

Common Problems This Part Can Address

  • Weak or inconsistent cabin heat
  • Coolant odor inside the vehicle
  • Heater core leakage
  • Restricted coolant flow through the HVAC core
  • Fogging caused by heater core seepage

Installation Notes and Tips

Verify the vehicle year, make, model, and front HVAC configuration before ordering. Drain the cooling system as required, inspect hoses and seals, and confirm the replacement core matches the original mounting and line connections. Because heater core replacement often requires access through the HVAC case, take care to preserve surrounding trim, ducts, and seals during disassembly.

Quality Assurance

Each OSC heater core is individually pressure tested. The aluminum construction and plated tubes are used to support durability in a direct-fit replacement for the listed Ford Explorer, Mercury Mountaineer, and Lincoln Aviator applications.
