Detailed Product Overview

The One Stop Solutions 98561 heater core is a direct replacement HVAC heater core engineered for vehicles originally designed around a copper-style core. OSC uses aluminum in place of the original copper design while maintaining OE-style dimensions and function. This makes it a practical choice for restoring heat output in 1965-1967 Ford LTD w/ A/C, 1967 Mercury Marquis w/ A/C, and 1968 Mercury Colony Park w/ A/C. This part cross-references Dorman - HELP 94561 for the same application.

Built for long-term durability, the core is manufactured from premium materials and tested for cycle, vibration, burst, and environmental resistance. The 98561 part number is a focused replacement for aging HVAC systems where internal corrosion, leakage, or reduced heat transfer has affected performance.

What This Heater Core Helps Solve

• Loss of cabin heat from a leaking or restricted heater core
• Coolant odor or moisture inside the passenger compartment
• Reduced heat output in high-mileage Ford LTD, Mercury Marquis, and Mercury Colony Park models
