Product Details

The Wehrli Custom Fabrication WCF100251-GM is a direct-fit aluminum upper coolant pipe engineered for the 2019–2024 RAM 2500/3500 equipped with the High Output (HO) 6.7L Cummins diesel engine. This precision-fabricated hard pipe replaces the factory OEM rubber upper coolant hose, delivering a more durable and visually cleaner engine bay solution built for the demands of the High Output cooling system.

Key Features:

  • Aluminum construction replaces the OEM rubber upper coolant hose for improved durability and longevity
  • Designed specifically for High Output (HO) 6.7L Cummins engines and their larger, upgraded factory radiator
  • Includes heavy-duty silicone boots for flexible, leak-free connections at each end
  • Includes stainless steel T-bolt clamps for secure, reliable clamping force
  • Powder-coated finish adds surface protection and a custom appearance under the hood
  • For use with the OEM RAM radiator — aftermarket radiators may cause fitment issues

OEM Cross-Reference: Replaces MOPAR part numbers 68359600AF, 68359600AD, 68359600AE.

Important: This part is compatible with High Output (HO) Cummins engines only, which are paired with a larger upgraded factory radiator. For Standard Output (SO) trucks, see WCF100223.

Wehrli Custom Fabrication (WCFab) is a leading manufacturer of performance diesel fabrication components for Cummins, Duramax, and Power Stroke platforms. The WCF100251-GM upper coolant pipe installs with basic hand tools and requires no other modifications on stock trucks.

Easy to use

This far is been great, we'll see how fast it shows up and how we'll it fits then update.

Fast, easy and efficient.

THMOTORSPORTS has a comprehensive database which itemized a ton of parts for my 2020 Range Rover Sport P525, which is exceedingly difficult to source parts for. Typically, on competitors sites- I might see 5-10 individual parts. THMOTORSPORTS came back with no less than 10 pages of applicable parts. I will do the majority of my future “heavy lifting” through their website.

Easy to find parts and had what I needed

Great prices!

easy

Great price and easy to order.

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.
