OVERVIEW
The N-910-680-01 Genuine VW/Audi coolant pump mounting bolt fastens the pump housing at the matching mounting position. The correct fastener helps secure the housing against its mounting surface without substituting a bolt of the wrong length or head style. Keep the required replacement hardware ready when servicing the matching pump.
Technical details
- OEM number: N-910-680-01 / N91068001.
- Catalog size: M6 x 28 mm.
- Head: low-profile head with an internal six-lobe drive, visible in the source photos.
- Quantity: one bolt; pump, seals and other mounting hardware are separate.
- Repair quantity: the documented coolant-pump repairs specify two new N-910-680-01 bolts and retain three longer mounting bolts.
Common reasons to replace
Use new bolts where the matching coolant-pump repair procedure specifies replacement. Also replace missing hardware or a fastener with damaged threads, a distorted head or a drive recess that no longer accepts the correct tool securely. Correct hardware avoids forcing a substitute into the pump housing or mounting threads.
A loose or damaged fastener calls for inspecting the housing, mating surface and receiving threads. Replacing a bolt alone will not correct a cracked housing, a damaged seal or stripped threads. Identify the exact mounting position before selecting hardware because the assembly uses different bolt lengths.
Service notes
Seat the pump correctly on its centering features and start the fasteners by hand. Follow the specified tightening order. Volkswagen’s matching GTI coolant-pump procedure specifies 9 Nm for the housing mounting bolts; verify the current procedure for the particular vehicle and assembly before applying that value.
Keep this housing mounting bolt separate from the coolant-pump drive-gear fastener. The drive-gear bolt has its own part number, thread direction and tightening procedure. Match the removed bolt and mounting position rather than using the pump name alone to choose hardware.
