It retains the hose against its fitting when the hose, fitting and clamp are in serviceable condition and the clamp is correctly positioned.\u003c\/p\u003e\u003cp\u003eThe published clamp size is not a universal hose inside-diameter specification. Match the original number and actual connection, including the hose outside diameter. Different hoses in the same engine assembly can require different clamp sizes and styles.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eReplace missing clamps, broken or deformed tabs, damaged bands, significant corrosion or clamps that no longer grip the assigned hose reliably. Inspect the clamp during heater hose or heater-core service and renew it whenever the applicable factory procedure requires replacement.\u003c\/p\u003e\u003cp\u003eEarlier repairs may leave an unsuitable worm-drive clamp or the wrong spring band size. Check the complete connection before fitting original hardware. A damaged hose or fitting must also be corrected rather than relying on a new clamp to conceal the defect.\u003c\/p\u003e\u003cp\u003eCoolant leakage or loss of heater performance requires diagnosis of the hoses, heater core, coolant fittings and cooling system. A new clamp cannot repair a cracked hose, damaged fitting or leaking heater core. Repair the diagnosed defect and inspect adjacent coolant hoses during the work.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the factory procedure for the exact heater hose arrangement. Work only after the engine and coolant have cooled. Follow the prescribed coolant pressure-release, draining and access steps. Record the original routing and assigned connection before removing hoses.\u003c\/p\u003e\u003cp\u003eUse the appropriate spring-clamp pliers and control the tabs while expanding the band. Do not over-expand or twist the clamp. Protect nearby components and avoid damaging the hose while moving the hardware.\u003c\/p\u003e\u003cp\u003eInspect the hose ends and fitting surfaces. Replace split, hardened or otherwise damaged hose as indicated by the repair procedure. Seat the correct hose fully on its assigned fitting before positioning the clamp at the specified location.\u003c\/p\u003e\u003cp\u003eRelease the clamp evenly so the band sits correctly around the connection. Check that the clamp is not skewed and its tabs have the required clearance. Do not install an incorrect size simply because it can be stretched over the hose.\u003c\/p\u003e\u003cp\u003eSpring band clamps do not use a screw-tightening torque. Follow the factory seating and positioning requirements for this connection rather than applying instructions intended for a worm-drive clamp.\u003c\/p\u003e\u003cp\u003eAfter assembly, verify hose routing, clamp seating and clearance, then refill and bleed the coolant system as specified, and complete the required operating and leak checks. Diagnose any remaining heater or coolant symptoms separately.\u003c\/p\u003e\u003cp\u003eThis listing supplies one original clamp.
