Key Features

• Specific-fit heater core for direct application matching
• Aluminum construction for efficient heat transfer
• Rear HVAC placement for listed Chrysler Aspen and Dodge Durango models
• Global Parts part number 8231655 for catalog and service reference
• Interchanges with select aftermarket reference numbers for fit verification

How It Works

The heater core is part of the vehicle’s HVAC system and uses engine coolant to transfer heat into the passenger compartment. On 2007-2009 Chrysler Aspen and 2004-2009 Dodge Durango rear HVAC systems, a worn or restricted core can reduce cabin heat, create uneven temperature output, or contribute to coolant odor and moisture inside the HVAC housing. Global Parts 8231655 provides the correct rear-position replacement for these applications.

Common Issues This Part May Resolve

• Weak or inconsistent rear cabin heat
• Coolant smell from the HVAC system
• Coolant seepage at the heater core housing
• Restricted coolant flow through the heater circuit
• Rear defrost or passenger comfort complaints tied to low heat output

Installation Notes and Tips

Verify rear-position fitment before ordering and confirm the vehicle matches the listed year, make, and model. Inspect coolant condition, hoses, clamps, and the HVAC housing during replacement, and flush the cooling system if contamination or debris is present. Adjustable pipe positioning is not provided on this unit, so line routing should be checked against the original part before installation.

Quality Assurance

Global Parts supplies this heater core as a specific-fit replacement built to match the listed applications. The aluminum design supports heat transfer performance in the rear HVAC system, and the part number 8231655 helps simplify catalog lookup and cross-reference verification.
