Pump, bracket, mounting stud, hoses, filter and other hardware are separate.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe shoulder provides the specified contact arrangement at the mounting point. Correct hardware retains the bracket in its assigned position so the pump and connected components remain supported. This nut does not form a hose connection or replace the fastener that attaches the pump itself to its bracket.\u003c\/p\u003e\u003cp\u003eThe same nominal M6 thread appears in many vehicle locations, but shoulder geometry and original part number still matter. Match N90175205 at the actual mounting point and inspect the separately specified stud or bolt before ordering.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eReplace damaged threads, rounded wrenching flats, deformation, missing hardware or corrosion affecting reliable installation. Replacement may also be appropriate after earlier repairs have left an incorrect substitute at the bracket mounting point.\u003c\/p\u003e\u003cp\u003eInspect the nut when the leak detection pump bracket is removed for diagnosis or component replacement. Follow any factory instruction to renew mounting hardware and check the mating stud or bolt for damage before fitting a new nut.\u003c\/p\u003e\u003cp\u003eLoose or damaged bracket hardware should be corrected as part of restoring the original mounting arrangement. A new nut cannot repair a cracked bracket, damaged body mounting point, defective pump or broken hose connection.\u003c\/p\u003e\u003cp\u003eEvaporative-emissions faults require system diagnosis. This mounting nut is a retaining component, so replacing it alone does not resolve an electrical pump fault, failed valve, leaking hose or defective emissions component. Repair the confirmed cause and ensure the mounting assembly is complete.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the factory procedure for the exact vehicle's leak detection pump and mounting bracket. Identify the bracket-to-vehicle attachment before removing hardware, and support the assembly so attached hoses and wiring are not strained.\u003c\/p\u003e\u003cp\u003eInspect the bracket, mounting surface and mating threads. Correct damaged components and position the bracket normally before installing the nut. Start it by hand without cross-threading and make sure the shoulder seats at the prescribed contact point.\u003c\/p\u003e\u003cp\u003eUse the correctly sized hex tool and the factory tightening requirement for this attachment. Do not transfer a torque from the pump-to-bracket screw, a parking brake cable bracket or another M6 fastener. Follow the specified thread preparation and hardware replacement instructions.\u003c\/p\u003e\u003cp\u003eDo not tighten the nut to pull a distorted bracket into place. If the mounting connection binds or does not seat correctly, inspect the bracket alignment and original hardware selection before continuing.\u003c\/p\u003e\u003cp\u003eAfter assembly, confirm the bracket is secure and connected hoses and wiring have their required routing and clearance. Complete the operating and diagnostic checks required by the component repair.
