Common Issues It May Resolve

• Weak or uneven cabin heat in a 2015-2017 Hyundai Tucson
• Coolant odor or moisture from a leaking heater core
• Restricted coolant flow through the HVAC heater circuit
• Fogging or poor defrost performance caused by heater core failure
• Temperature inconsistency during cold-weather driving

Installation Notes and Tips

Verify vehicle fitment by year and model before installation. The heater core is located within the HVAC case, so access typically requires disassembly of interior heating and air conditioning components. Inspect coolant condition, hoses, and seals during replacement, and flush the cooling system if contamination is present. Confirm the included pipes match the original configuration on the vehicle before assembly.
