Detailed Description

This Global Parts heater core, part number 8231477, is engineered for vehicles that rely on the engine cooling system to deliver warm air through the HVAC system. It is a specific-fit aluminum unit for Ford Explorer, Ford Explorer Sport Trac, Mercury Mountaineer, Lincoln Aviator, and Ford Explorer Sport applications listed in the fitment data.

What It Helps Resolve

• Weak or no cabin heat
• Coolant smell inside the passenger compartment
• Fogging or poor windshield defrost performance
• Internal heater core leakage
• Restricted coolant flow through the HVAC heater circuit

Installation Notes and Tips

Verify the vehicle’s year, make, and model against the listed fitment before ordering. This heater core uses a specific fit and does not include adjustable pipe positioning. Because heater core replacement often involves HVAC case access and coolant drainage, confirm hose routing and system condition during service. For best results, inspect related cooling-system components and refill the system with the correct coolant after installation.

Quality Assurance

Global Parts 8231477 is built as an aluminum heater core for the listed applications and follows the fitment details provided for direct replacement use.
