www.thingiverse.com/thing:370...
Specification state that this nut should be fastened to 96-120 in. lb. (11-14 N*m) which can be achieved with this tool if printed at 100% infill with good layer adhesion. Note in the images how far the nut is tightened on the water pipe nipple - shown at proper torque. If the nipple isn't protruding as far, it may be because it isn't set correctly in the bell housing. The square frame on the water pipe nipple fits into a square slot in the back of the bell housing.
Volvo Part Number may be 3850601 (Spanner Wrench), but not sure if this part number is exactly the same size.
This tool can be used with either a wrench or a 41 mm socket.
