Follow the engine repair procedure for fastener renewal. Replace a bolt with damaged threads, a worn internal drive, deformation or corrosion affecting its seating area. Hardware with an uncertain service history should be assessed against the factory replacement requirements before reassembly.\u003c\/p\u003e\u003cp\u003eA replacement bolt cannot correct bearing wear, a damaged crankshaft journal or a distorted cap. Diagnose the cause of low oil pressure, bearing noise or internal engine damage, and inspect the relevant components before deciding which parts the repair requires.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eConfirm the original engine, cylinder-block configuration and bolt location before ordering. Main bearing cap hardware must be selected for the actual mounting assignment rather than by appearance alone. Keep caps in their prescribed positions and orientation, and follow the repair instructions for cleanliness, bearing inspection and clearance measurement.\u003c\/p\u003e\u003cp\u003eInspect the mating threads and bolt seating surfaces. Use the correct multi-point bit fully engaged in the head. Follow the engine-specific instructions for new fasteners, lubrication or thread preparation, tightening sequence, torque and any additional angle step. Do not apply a generic torque based only on the bolt's appearance. Complete the required rotation and clearance checks before finishing assembly.\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 GTI\u003c\/td\u003e\n\u003ctd\u003e2008\u003c\/td\u003e\n\u003ctd\u003e2.0L turbo gasoline; verify engine and original bolt assignment by VIN\u003c\/td\u003e\n\u003ctd\u003eBase; four-door hatchback; Transmission does not establish engine main-bearing bolt fitment\u003c\/td\u003e\n\u003ctd\u003eUse only at the engine bearing-cap mounting position specifying N91063901.
