Detailed Description

This Continental radiator coolant hose is engineered for cooling-system service where the original hose shape and dimensions matter. With a 1.310-inch inside diameter at both ends and a 23.710-inch length, part number 66193 matches the molded layout needed for select upper and lower coolant hose applications. It fits 2015-2020 Cadillac Escalade, upper; 2015-2020 Chevrolet Tahoe, upper; 2014-2019 Chevrolet Silverado 1500, upper; and 2004-2008 Mitsubishi Endeavor, lower. This part cross-references Gates 22870 and Dayco 72616 for the same application.

Continental’s Molded line focuses on replacement hoses formed to follow the original routing and connection points. That makes 66193 a practical choice when the existing hose has softened, cracked, or lost its shape. The same part number 66193 also covers additional Cadillac Escalade ESV, Chevrolet Suburban, GMC Yukon, GMC Sierra, and related fitments listed for upper or lower positions.

Common Issues This Hose Can Address

• Coolant leaks from a cracked or aged hose.
• Loss of hose shape that affects routing and sealing.
• Softening or deterioration from heat and coolant exposure.
• Replacement needs after a hose fails inspection.
• Fitment concerns when an exact molded profile is required.

Installation Notes and Tips

Verify the vehicle year, make, model, and hose position before installation. This hose is listed for molded upper and lower applications depending on the vehicle, and some fitments note cut-to-fit use. Confirm the inside diameter and length against the original hose before removal. Inspect clamps, necks, and adjoining cooling-system components for wear before installing the replacement hose.

Quality Assurance

Continental states that the EPDM tube and cover with synthetic reinforcement meets or exceeds SAE 20R4EC Class D1 specifications. The exact OEM configuration supports consistent fitment across the listed applications, including Cadillac Escalade, Chevrolet Silverado 1500, and GMC Sierra models. Part number 66193 is identified for straightforward ordering and verification.
