How to Replace the Heater Radiator on a Volkswagen Jetta?

Model: Volkswagen Jetta MK 6, A6 - Years 2010-2018
Part: Heater core

To replace the heater radiator on a Volkswagen Jetta, open the bonnet to access the rear of the engine bay. Here, you will find the fastening screws that need to be loosened and the connecting pipes that must be disconnected. Once the fastening elements are removed, access the cabin by removing the side cover of the driver's footwell. This will allow you to slide the old radiator out from inside its compartment so that a new one can be installed, connecting and securing it properly.
