Match the fastener to the actual hose connection before ordering.\u003c\/p\u003e\u003ch3\u003eTechnical details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOriginal part number: N-104-154-02 \/ N10415402.\u003c\/li\u003e\n\u003cli\u003ePublished nominal size: M8 x 40.\u003c\/li\u003e\n\u003cli\u003eSocket-head bolt with a washer beneath the head, as shown in the original photograph.\u003c\/li\u003e\n\u003cli\u003eCataloged earlier part number: N10415401.\u003c\/li\u003e\n\u003cli\u003eOne bolt supplied. Hose, compressor, seals and refrigerant are separate.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe hose attachment must remain seated in the designed compressor connection. The correct bolt length and contact arrangement are necessary for assembling that joint as specified. Other M8 fasteners may have different lengths, heads or assigned mounting positions.\u003c\/p\u003e\u003cp\u003eThe mounting bolt retains the attachment; the separate connection seal provides the refrigerant seal. Replacing hardware alone does not repair a cracked fitting, damaged hose or deteriorated sealing ring. Inspect the complete connection when diagnosing a leak.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eReplace a missing bolt or one with damaged threads, a stripped drive recess, visible deformation or corrosion that affects serviceability. Renew hardware after removal whenever the factory procedure calls for replacement.\u003c\/p\u003e\u003cp\u003eCompressor or hose replacement can reveal prior overtightening or driver damage. Inspect the mating threaded hole and hose attachment as well as the bolt before reassembly. Damage to either component requires attention before tightening new hardware.\u003c\/p\u003e\u003cp\u003ePoor cooling, unusual compressor operation or refrigerant loss can have several causes. Diagnose the system and identify the faulty component instead of assuming the attachment bolt is responsible. Do not overtighten the connection to compensate for a leak.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the repair procedure for the exact compressor and hose arrangement. If the refrigerant circuit must be opened, recover the refrigerant with the prescribed equipment before disconnecting the line.\u003c\/p\u003e\u003cp\u003eConfirm the original part number at the assigned connection. Keep the hose aligned without strain and install the correct separate seal when required. Check that the connection surfaces and threaded hole are undamaged and prepared as directed.\u003c\/p\u003e\u003cp\u003eUse the correct driver for the actual recess shown on the supplied fastener. Engage it fully, start the bolt by hand and confirm normal seating before final tightening. A bolt that binds or fails to seat can indicate incorrect hardware, poor alignment or damaged threads.\u003c\/p\u003e\u003cp\u003eUse the tightening specification for this connection. Do not calculate torque from the M8 x 40 designation or transfer a value from a compressor bracket bolt. Follow the prescribed instructions for thread treatment and hardware replacement.\u003c\/p\u003e\u003cp\u003eAfter service, complete the specified leak and functional checks. Use the refrigerant and lubricant required by the actual vehicle during any system servicing. This listing supplies one mounting bolt and contains no fluid or pressurized component.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eVehicle\u003c\/th\u003e\n\u003cth\u003eModel years\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eConfiguration\u003c\/th\u003e\n\u003cth\u003eApplication restrictions\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi RS4\u003c\/td\u003e\n\u003ctd\u003e2007–2008\u003c\/td\u003e\n\u003ctd\u003e4.2L naturally aspirated V8, BNS\u003c\/td\u003e\n\u003ctd\u003eB7 sedan, quattro; 6-speed manual\u003c\/td\u003e\n\u003ctd\u003eSpecified compressor-to-condenser hose attachment at the compressor.
