The Agility Autoparts Heater Core 9010536 is an aluminum replacement that carries hot engine coolant through its tubes and fins, so the blower can warm the air for cabin heat and the windshield defroster. It fits many Volkswagen, Audi and SEAT models, among them the 2006-2011 Volkswagen Jetta, 2011-2014 Volkswagen Golf and 2010-2017 Volkswagen GTI. It is a direct-fit replacement for the listed applications, and the Buyer's Guide tab has the full list.
Signs a heater core may need replacing include a sweet coolant smell inside the cabin, a greasy film fogging the windshield, damp carpet, weak or no heat, and unexplained coolant loss. Low coolant, a thermostat fault or a blend-door problem can cause similar symptoms, so diagnose the cause before replacing. If the original core is leaking or restricted, this unit replaces it. The listed applications use one heater core. Country of origin: China.

Is this a direct-fit VW Jetta heater core replacement?
Yes. It is a direct-fit replacement for the 2006-2011 Volkswagen Jetta. It also fits the 2011-2014 Volkswagen Golf and 2010-2017 Volkswagen GTI; see the Buyer's Guide tab for the other models.
What does an HVAC heater core do?
It works like a small radiator behind the dash. Hot engine coolant flows through its tubes and fins, and the blower pushes air across it to heat the cabin and supply the defroster.
What is this heater core made of, and how big is it?
The core and tanks are aluminum. The core measures 7.125 in wide, 7.1875 in high and 1.000 in deep, with O-ring inlet and outlet connections.
What signs suggest a heater core may need replacing?
Common signs include a sweet coolant smell in the cabin, a greasy film on the windshield, damp carpet, weak heat or coolant loss. Diagnose first, because other cooling-system faults can cause similar symptoms.
How is this heater core tested?
Agility builds its heaters under ISO TS16949 quality systems and leak tests every one. It also fitment-checks them in the vehicle's HVAC heater module for a drop-in fit.
