Detailed Description

It is specified for 2002-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, 2002-2010 Mercury Mountaineer, and 2003-2005 Lincoln Aviator, all in the front position and with a 2-inch core.

What It Helps Address

  • Weak or inconsistent cabin heat
  • Coolant leakage inside the HVAC case
  • Restricted coolant flow through the heater circuit
  • Fogging or sweet odor caused by heater core seepage
  • HVAC performance loss from a damaged or corroded core

Installation Notes and Tips

Verify the vehicle uses a 2-inch core and confirm the front heater core location before ordering. Compare the inlet and outlet pipe diameters, core height, core width, and core thickness against the removed unit to ensure proper fitment. On vehicles such as the Ford Explorer, Explorer Sport Trac, Mercury Mountaineer, and Lincoln Aviator, access to the heater core typically requires HVAC case service, so inspect related seals, hoses, and coolant condition during replacement.

Quality Assurance

This APDI heater core is built with aluminum construction and listed dimensional specifications for the stated applications. It cross-references Four Seasons 90045 for the same application.
