Stop Coolant Leaks Before They Leave You Stranded

A small coolant leak can turn into a major headache if it is left unchecked, especially when it starts at a weak factory fitting. The S&B 83-1013 Heater Core Supply Hose is built to replace the failure-prone OEM hose with a stronger and more dependable solution that is designed to last. Instead of relying on a plastic fitting that can crack from years of engine heat, S&B upgrades the design with a durable stainless steel fitting that stands up to demanding conditions. Additionally, the heavy-duty silicone wrapped hose offers excellent resistance to heat and wear, giving you greater confidence every time you drive. This upgrade helps reduce the chances of unexpected coolant loss that could leave your truck sidelined. Whether your truck is a daily workhorse or a long distance tow rig, investing in a permanent solution now can help you avoid costly repairs later. It is a straightforward upgrade that delivers lasting peace of mind for your 2003-2024 Dodge Ram 2500 or 3500 equipped with the 5.9L or 6.7L Cummins engine.

Engineered To Outlast The Factory Heater Hose

The S&B 83-1013 Heater Core Supply Hose is specifically engineered to address one of the common failure points found on 2003-2024 Dodge Ram 2500 and 3500 trucks with the 5.9L and 6.7L Cummins diesel engine. The factory heater hose uses a plastic fitting near the cylinder head that is known to become brittle over time after repeated exposure to high engine temperatures. S&B replaces that weak point with a precision stainless steel fitting that offers significantly greater strength and resistance to cracking. Furthermore, the heavy-duty silicone wrapped hose is designed to withstand the demanding environment found in the engine bay while maintaining reliable coolant flow to the heater core. This direct replacement installs in place of the original component, making it an ideal upgrade during preventative maintenance or when repairing a coolant leak. The result is a more durable cooling system component that helps improve long term reliability without requiring unnecessary modifications. Best of all, this replacement is street legal in all 50 states, making it a dependable upgrade that you can install with confidence.
