Product Description
MOPAR 68359638AC RADIATOR HOSE - LOWER FOR 19-23 RAM 2500/3500 WITH 6.7L CUMMINS ENGINE
Maintain proper engine cooling performance and OEM reliability with the genuine Mopar 68359638AC Lower Radiator Hose for 2019-2023 Ram 2500 and 3500 trucks equipped with the powerful 6.7L Cummins turbo diesel engine. Designed to meet strict factory specifications, this OEM lower radiator hose delivers dependable coolant flow, temperature regulation, and long-lasting durability under demanding towing and heavy-duty operating conditions.
The Mopar 68359638AC radiator hose is engineered to withstand repeated heat cycles, coolant pressure, vibration, and harsh diesel operating environments. Over time, factory radiator hoses can crack, swell, soften, or deteriorate, potentially leading to coolant leaks, overheating, and costly engine damage. Replacing worn cooling system components with genuine Mopar parts helps preserve engine efficiency and cooling system integrity.
Manufactured using OEM-quality reinforced rubber materials and precision-molded connections, this direct-fit lower radiator hose ensures proper fitment with factory cooling system components. Unlike generic aftermarket hoses, genuine Mopar hoses are specifically engineered for the cooling demands of Ram heavy-duty Cummins applications.
This lower radiator hose is commonly used on trucks equipped with the 68RFE automatic transmission and replaces previous part number 68359638AB.
