The factory heater core supply hose on Cummins-powered Ram trucks is known to be leak-prone, and a leak here means coolant loss and a cabin that stops heating. The S&B Heater Core Supply Hose is a direct replacement for that OEM part, made from higher quality materials, and S&B says it is built to last a lifetime.
This is a straightforward service part. There is no tuning or performance angle, just a more durable hose in a spot where the original has a poor track record.
Fitment
2003-2024 Ram 2500 and 3500 with the 5.9L or 6.7L Cummins diesel. The listing does not state trim, cab or driveline exclusions, so if you have a chassis cab or an unusual configuration, check with us before ordering.
Install notes
S&B does not provide install details in this listing. As with any coolant hose, plan on draining coolant, and refill and bleed the system afterward.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text us at (920) 249-7744.

Frequently bought together
Why it works
Stops the leaking coolant fitting
The OEM plastic fitting near the cylinder head tends to crack and leak with heat and age. This hose replaces it with a stainless steel fitting and heavy-duty wrapped silicone hose.
Installation
Bolt-on with hand tools. Grab the manufacturer’s step-by-step instructions, or watch the install first. Stuck partway? Call real humans at (920) 249-7744.
