Precision Fit Cooling Performance For Long Term Reliability

The Wehrli 100517 Upper Coolant Pipe is designed as a high-performance replacement for the OEM upper coolant hose on 2010–2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Constructed from durable aluminum, this pipe improves heat resistance and long-term reliability under high-load conditions compared to traditional rubber hoses. The kit includes reinforced silicone boots and stainless steel T-bolt clamps to ensure a secure and leak-free seal, even under elevated coolant pressures. The single-stage powder-coated finish enhances corrosion resistance and provides a clean, professional appearance under the hood. This pipe is compatible only with the OEM RAM radiator and is not designed for aftermarket radiators or setups with twin CP3 pumps. Trucks from model years 2013 to 2015 equipped with dual radiators will require Wehrli model WCF100867 instead. By eliminating the risk of hose degradation and improving fit and flow, this coolant pipe supports more consistent cooling performance and a longer service life for critical engine components.
