The molded design of the Gates 21719 hose provides a precise fit with two different inside diameters at each end—1.25 inches (32 mm) and 1.57 inches (40 mm)—to match the specific radiator and engine connections. With a centerline length of 14.8 inches (376 mm), this hose is engineered to maintain proper coolant flow without kinks or restrictions. The absence of an internal spring allows for smooth coolant circulation, reducing the risk of hose collapse under vacuum conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement of worn or cracked radiator coolant hoses in Buick Cutlass and Cutlass Supreme\u003c\/li\u003e\n\u003cli\u003eAddressing coolant leaks in Chevrolet Lumina and Pontiac Grand Prix cooling systems\u003c\/li\u003e\n\u003cli\u003eRestoring proper coolant flow in Oldsmobile Regal engines\u003c\/li\u003e\n\u003cli\u003ePreventing overheating caused by deteriorated or misshapen hoses\u003c\/li\u003e\n\u003cli\u003eEnsuring secure hose connections without the need for additional fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify compatibility with your vehicle’s make and model before installation\u003c\/li\u003e\n\u003cli\u003eEnsure all clamps and fittings are clean and free of debris\u003c\/li\u003e\n\u003cli\u003eLubricate hose ends with coolant or water to ease installation\u003c\/li\u003e\n\u003cli\u003eInspect surrounding components for wear or damage during replacement\u003c\/li\u003e\n\u003cli\u003eProperly torque clamps to manufacturer specifications to avoid leaks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eGates Molded Coolant Hose 21719 is manufactured to meet or exceed OEM standards for durability and performance.
