Detailed Description

CSF 3722 is a replacement radiator built for factory-style cooling system service on Volkswagen Jetta Hybrid and Volkswagen Passat applications. The aluminum core helps transfer heat efficiently, while the plastic tank construction follows the OE-style layout used on the original cooling assembly. The cross-flow configuration and quick-connect pipe connections support a clean fit in the engine bay where the original radiator uses right-side inlet and outlet routing.

CSF has produced radiators for decades and supplies a broad range of vehicle applications worldwide. This part cross-references BBB Industries 13273 for the same application.

What This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Restricted cooling performance from a damaged core
• Overheating caused by radiator deterioration
• Factory-style replacement needs after cooling system repair
• Fitment-specific service for Volkswagen Jetta Hybrid and Passat cooling systems

Installation Notes and Tips

Verify the vehicle’s radiator connection style, inlet and outlet orientation, and core dimensions before installation. This radiator uses quick-connect inlet and outlet pipe fittings and does not include a radiator cap. Confirm that the vehicle is a 2013-2016 Volkswagen Jetta Hybrid or a 2012-2014 Volkswagen Passat before ordering.
