What It Is
A complete heater core replacement kit for Mk5 and Mk6 models, addressing the clogging that's a known cause of poor heater performance on these cars.
How to Know If Your Heater Core Is the Problem
If your engine reaches and holds 190-200°F with no overheating issues, but the heater still doesn't blow warm well, a clogged heater core is a likely cause. Heater cores clog over time from coolant age and contamination.
What's Included
Installation Note
Removing the heater core actually spills very little coolant, but KermaTDI recommends a cooling system flush before starting the replacement, given that coolant age and contamination are usually what caused the clog in the first place.
Fitment
2009-2014 Volkswagen Golf, Jetta, and Jetta Sportwagen.
Common Questions
How do I know if my heater core is clogged rather than something else?

No, removing the heater core spills very little coolant, though a cooling flush is recommended before starting.
Is the coolant included?
Yes, 3 units of G13 coolant are included in the kit.
