Give Your High Output Cummins A Cooling Upgrade Built To Last

The factory rubber upper coolant hose gets the job done, but the Wehrli WCF100251 High Output Upper Coolant Pipe gives your 2019-2026 RAM 2500 or 3500 6.7L Cummins a more substantial solution under the hood. Its aluminum construction replaces the OEM rubber hose with a rigid pipe designed for the demands of the High Output Cummins cooling system. That makes it an appealing upgrade for owners who value durable components and want to clean up the appearance of their engine bay at the same time. Silicone boots provide the flexible connections needed at each end, while included T bolt clamps help keep those connections securely in place. What's more, the powder coated finish adds surface protection while giving you multiple color options for matching other upgrades or adding a custom touch. The pipe is designed specifically for trucks equipped with the High Output engine option and its larger upgraded radiator, helping ensure the component matches the correct factory cooling configuration. If you want to replace a factory rubber component with a purpose built aluminum alternative, the WCF100251 brings together durability, fitment, and underhood style in one straightforward upgrade.

Purpose Built For The High Output Cummins Cooling System

The Wehrli WCF100251 is engineered specifically for 2019-2026 RAM 2500 and 3500 trucks equipped with the 6.7L High Output Cummins and the corresponding upgraded factory cooling system. Rather than serving as a universal replacement, this aluminum upper coolant pipe is designed around the larger radiator configuration found on High Output models. It is intended for use with the OEM RAM radiator, so trucks running an aftermarket radiator may encounter fitment issues depending on the radiator design. The assembly includes silicone boots and T bolt clamps to provide the necessary connections between the rigid aluminum pipe and the factory cooling system. Additionally, the pipe replaces MOPAR part numbers 68359600AF, 68359600AD, and 68359600AE, making it easy to confirm the factory component being replaced. Multiple powder coat color choices allow the pipe to complement other engine bay components while providing a finished surface on the aluminum construction. Owners of Standard Output Cummins trucks should use Wehrli WCF100223 instead, since the WCF100251 is compatible only with the High Output engine and cooling system.
