Chevrolet 4500 Coolant Tank Kit - Wehrli - Fabricated Aluminum - Gloss White - '19-'27. This direct-fit reservoir installs in the OEM location and brings durable, clean construction to your 4500’s engine bay.

Factory plastic tanks can yellow over time and their non-replaceable sensors often trigger false low-coolant warnings. Wehrli’s fabricated aluminum tank addresses both with robust construction and a serviceable float-type level sensor. A billet sight glass lets you check level at a glance, and the black anodized billet cap provides a precise seal. Finished in gloss white powder coat, the kit includes hardware for straightforward installation on 2019+ Chevrolet 4500 L5D Duramax trucks.
