Detailed Description

This APDI heater core is engineered for Volkswagen HVAC systems that use a compact aluminum core design. The listed dimensions and 3/4-inch pipe diameters help match the factory-style heater core layout found in many Volkswagen Passat, Volkswagen Beetle, and Volkswagen Tiguan models, along with select CC, Eos, Golf, GTI, Golf SportWagen, Passat CC, and R32 applications. If you are replacing a leaking or restricted heater core, APDI 9010554 provides the core and tank construction needed for heater circuit service.

This part cross-references Four Seasons 92186 for the same application.

What It Helps Fix

• Loss of cabin heat in Volkswagen Passat, Beetle, Tiguan, and related models
• Coolant odor or moisture inside the passenger compartment
• Restricted coolant flow through the heater circuit
• Uneven or weak defrost performance caused by poor heater output
• Leakage from a corroded or damaged heater core

Installation Notes and Tips

• Verify vehicle fitment by year, model, and any listed notes before installation.
• Confirm the inlet and outlet pipe diameters match the original heater core connections.
• Inspect heater hoses, clamps, and coolant condition during replacement.
• Flush the cooling system if contamination or debris is present.
• Bleed the cooling system carefully after installation to remove trapped air.
