Can I pick up my order or have it installed at your shop?

Absolutely. We offer local pickup on most products and full professional installation at our shop in Washington, MO. Whether you just want to grab your parts or have our techs handle the install, we’ve got you covered. Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Factory rubber upper coolant hoses collapse, weep and eventually let go. The Wehrli Upper Coolant Pipe (Manufacturer Part # WCF100678) replaces it on your 2003-2009 Dodge Ram 2500/3500 5.9L and 6.7L Cummins with a powder coated aluminum pipe with bead-rolled ends, silicone boots and stainless T-bolt clamps. Roughly a 30 minute job.

Why Choose the Wehrli Upper Coolant Pipe?

  • Aluminum instead of aging rubber – no more collapsing hose or a slow coolant weep you keep topping up.
  • Bead-rolled ends – gives the silicone boots something to grip so the clamps hold without slipping.
  • Complete and ready to fit – silicone couplers and T-bolt clamps included.
  • Covers both engines – one pipe for the 5.9L and the 6.7L across 2003-2009.
  • Finishes the engine bay – matches Wehrli's thermostat housings, coolant tanks and intake kits in the same powder coat range.
  • Made in the USA.
