ACDelco 15-63840 Air Conditioning Evaporator Core Kit with Valves and Seals

The ACDelco 15-63840 is a GM Genuine Parts air conditioning evaporator core kit designed to restore reliable cooling performance to your vehicle's HVAC system. This complete evaporator assembly is a GM-recommended replacement for your vehicle's original factory component, engineered to meet the rigorous standards set by General Motors.

What It Does:

The A/C evaporator core is a critical heat exchanger located in the HVAC housing where it cools and dehumidifies cabin air. Refrigerant is metered into the evaporator by the orifice tube or expansion valve, absorbing heat from the air before it's blown through your vehicle's vents.

Key Features:

• Complete kit includes evaporator core, valves, seals, stud, plates, and bolt for comprehensive replacement
• GM Genuine Parts original equipment quality ensures proper fit, form, and function
• Designed and validated by GM engineers specifically for Chevrolet, Buick, GMC, and Cadillac vehicles
• Meets GM factory specifications for safety and performance standards
• Aluminum construction provides durability and resistance to corrosion
• Vacuum-brazed and leak-tested for trouble-free operation

Installation Notes:

This evaporator assembly replaces worn or leaking A/C evaporator cores. Common symptoms of evaporator failure include insufficient cooling, weak airflow, warm air from vents, musty odors, or visible condensation inside the vehicle cabin. Professional installation is recommended as the A/C system requires proper refrigerant recovery and recharging.
