Universal Air Conditioner HT399088C HVAC Heater Core Aluminum OE Replacement

The Universal Air Conditioner (UAC) HT399088C is an OE-replacement aluminum HVAC heater core engineered to restore proper cabin heating and defrost performance. Warm engine coolant circulates through the heater core's fins, and the blower motor pushes air over those fins and into the cabin — delivering reliable heat on cold days.

Over time, heater cores can develop leaks or become clogged, resulting in symptoms such as a sweet smell from the vents, reduced heating output, fogged or undefrosted windows, or coolant found on the cabin floor. When flushing fails to restore performance, a direct-fit replacement like the HT399088C is the correct solution.

Key Features:

• Aluminum construction for durability and efficient heat transfer
• OE-equivalent fit — engineered to match original equipment dimensions and connections
• Pressure tested for leak-free performance prior to leaving the factory
• ISO/TS 16949 quality standards — manufactured to meet or exceed OEM specifications
• Inlet diameter: 16 mm | Outlet diameter: 19 mm
• Core dimensions: 149 mm (W) × 178 mm (H) × 25 mm (D) — approximately 5.87" × 7.01" × 0.98"
