Description

A coolant tank that looks the part

Wehrli's fabricated aluminum tank mounts in the factory coolant tank location and replaces the clear plastic reservoir, which tends to look tired with age. It has a sight glass for checking the level at a glance and a black anodized billet cap.

It fits stock trucks, uses the factory mounting points and installs with basic hand tools.

Who it's for

6.6L L5P Duramax owners cleaning up the engine bay or replacing a worn plastic reservoir.
