It is formed to match factory-style bends and is suitable for coolant, water, and air service, with marine application approval.\u003c\/p\u003e\u003cp\u003eCompatible with 2000-2005 Buick LeSabre engine to heater, 2002-2005 Buick Park Avenue engine to heater, and 2002-2005 Pontiac Bonneville engine to heater, this molded heater hose supports direct-fit replacement needs for common GM heater circuit routing. The Gates Molded Heater Hose line focuses on factory-shaped hoses for smaller, tighter-fitting engine compartments.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGates part number 18569 molded heater hose\u003c\/li\u003e\n\u003cli\u003eFactory-molded, OE-style shape for accurate routing\u003c\/li\u003e\n\u003cli\u003eEPDM construction for coolant-system service\u003c\/li\u003e\n\u003cli\u003eEnd I.D. 0.61 in. \/ 15 mm at both ends\u003c\/li\u003e\n\u003cli\u003eCenterline length: 25.4 in. \/ 645 mm\u003c\/li\u003e\n\u003cli\u003eApproved for coolant, water, air, and marine applications\u003c\/li\u003e\n\u003cli\u003eDesigned for engine-to-heater routing in compact engine compartments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eThis molded heater hose is built to replace a formed coolant hose in the engine-to-heater circuit. The EPDM material is commonly used in cooling-system hose applications, and the molded profile helps maintain the correct path around nearby components in crowded engine bays. If you are replacing a worn or leaking heater hose on a Buick LeSabre, Buick Park Avenue, or Pontiac Bonneville, Gates 18569 provides the correct molded layout for the listed applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references CSF 10569 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Hose Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCoolant leaks from a cracked or aged heater hose\u003c\/li\u003e\n\u003cli\u003eImproper hose routing after a previous repair\u003c\/li\u003e\n\u003cli\u003eSoftening, swelling, or deterioration of the original EPDM hose\u003c\/li\u003e\n\u003cli\u003eRestricted heater flow caused by a damaged hose section\u003c\/li\u003e\n\u003cli\u003eFitment issues in tight engine compartments where a straight hose will not follow the factory path\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify hose routing against the original part before installation, especially on engine-to-heater applications where bends and length are critical. Inspect adjoining heater pipes, clamps, and connection points for corrosion or wear before installing the new hose. Confirm the 0.61-inch end diameters and 25.4-inch centerline length match the vehicle’s factory routing requirements.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eGates is known for OE-style hose construction and application-specific molded designs.
