It is supplied individually for pipe, hose fitting or related cooling-system service.\u003c\/p\u003e\u003ch3\u003eTechnical details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOriginal number: N-907-653-01 \/ N90765301.\u003c\/li\u003e\n\u003cli\u003ePublished nominal dimensions: 32 x 4 mm.\u003c\/li\u003e\n\u003cli\u003eSpecified application: cooling-line end-fitting sealing connection.\u003c\/li\u003e\n\u003cli\u003eOne O-ring supplied. Cooling line, end fitting, other seals, fasteners and coolant are separate.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe O-ring forms the fluid seal at its assigned pipe connection. Correct dimensions and undamaged mating surfaces allow the tube and housing to assemble with the intended sealing arrangement. The ring does not replace the pipe, housing or separately specified retaining hardware.\u003c\/p\u003e\u003cp\u003eA cooling-system assembly can contain several similar-looking rings at different connections. Match N90765301 at the actual cooling line before ordering. This pipe seal is distinct from a thermostat perimeter gasket or coolant temperature sensor seal.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eRenew the ring when the pipe connection is opened and the applicable service procedure requires a new seal. Replace a ring that is cut, flattened, hardened, swollen or otherwise damaged, or one that no longer seats correctly in its assigned position.\u003c\/p\u003e\u003cp\u003eCoolant residue or a diagnosed leak at the cooling-line connection can indicate a sealing issue. Inspect the tube, coolant fitting and neighboring coolant components to establish the actual source before selecting repair parts.\u003c\/p\u003e\u003cp\u003ePrevious installation can pinch or twist a ring, while an incorrect substitute may prevent the pipe from seating normally. Replace unsuitable sealing hardware and inspect the housing contact area before reassembly.\u003c\/p\u003e\u003cp\u003eA new ring cannot repair a cracked housing, damaged pipe end, distorted sealing bore or leak from a nearby hose. Correct the diagnosed component fault before completing the connection. Cooling performance complaints also require diagnosis of the wider system.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the factory procedure for the exact coolant line and end-fitting arrangement. Allow the cooling system to cool and release pressure as prescribed before opening the connection. Collect coolant using the required service method.\u003c\/p\u003e\u003cp\u003eRemove the old ring carefully and inspect the pipe sealing area and housing bore. Clear old seal material and debris without damaging the contact surfaces. Correct a cracked, corroded or distorted mating component before installing the new seal.\u003c\/p\u003e\u003cp\u003eFit the ring in its prescribed position and use only the installation preparation specified by the procedure. Avoid twisting, cutting or pinching the ring as the pipe enters the housing.\u003c\/p\u003e\u003cp\u003eSeat the pipe fully and install the correctly specified retaining hardware. Do not use fastening force to draw an incorrectly aligned pipe into place or to compensate for an unsuitable seal. Check engagement and component positioning before refilling.\u003c\/p\u003e\u003cp\u003eRestore the cooling system with the specified coolant and filling or bleeding procedure. The O-ring number does not establish coolant specification, fill quantity or thermostat operating temperature. Select fluid and other service components separately for the vehicle.\u003c\/p\u003e\u003cp\u003eComplete the required leakage and operating-temperature checks after assembly. If seepage persists, inspect pipe seating, seal condition and both mating surfaces before continuing operation. This listing supplies one original O-ring rather than a complete coolant fitting seal kit.\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\u003eVolkswagen Passat GLS\u003c\/td\u003e\n\u003ctd\u003e2004–2005\u003c\/td\u003e\n\u003ctd\u003e1.8L turbocharged gasoline, AWM\u003c\/td\u003e\n\u003ctd\u003eB5.5 Sedan, front-wheel drive; Manual transmission only\u003c\/td\u003e\n\u003ctd\u003eSpecified 32 x 4 seal at the assigned cooling-line end fitting.
