Its pre-formed shape helps match the original hose routing, reducing the need to force a straight hose into a curved path. The EPDM material is commonly used in cooling-system service for its resistance to heat and coolant exposure. This hose measures 19 mm, or 3\/4 inch, at both ends and has a 587 mm centerline length, making it a precise option for the listed HVAC hose applications. If you are replacing a worn heater hose on a 1989-1991 Chevrolet Cavalier, 1990-1991 Chevrolet Corsica, 1990-1991 Pontiac Tempest, or 1989 Buick Skyhawk, Gates 19613 provides the correct molded routing for the specified heater-to-intake-manifold or heater-to-engine positions. This part cross-references Dayco 88360 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Hose Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracked or hardened heater hose material\u003c\/li\u003e\n\u003cli\u003eIncorrect routing in a compact engine compartment\u003c\/li\u003e\n\u003cli\u003eCoolant seepage at a worn hose section\u003c\/li\u003e\n\u003cli\u003eRestricted fitment from using a non-molded replacement hose\u003c\/li\u003e\n\u003cli\u003eService replacement for heater circuit hose damage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the hose routing, end diameters, and centerline length before installation. Compare the original hose shape to the molded profile of Gates 19613 to confirm the heater-to-intake-manifold or heater-to-engine path matches your vehicle. Inspect adjoining clamps, fittings, and connection points for wear or corrosion before installing the new hose.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eGates manufactures molded coolant and heater hoses to OE-style specifications for accurate fit and routing.
