TORQUE SETTINGS
This post is a place to post torque settings for various parts of the INEOS Grenadier. I will add more as I find them, but feel free to post any settings you know.
You can convert Newton metres (Nm) to foot pounds and vice versa here.
WHEEL NUTS
Steel rims 180 Nm.
Alloy rims 160 Nm.
Spare tyre on back:
TBC (but 120Nm has worked for me on other cars, but I check regularly when going remote)

The US Owner's Manual, on page 130, only gives one figure 160 Nm. Not 160Nm for alloy and 180Nm for steel rims.
WHEEL STUD SIZE AND THREAD
Wheel stud size and thread is M14x1.5 (

TERMINAL SCREWS/NUTS ON CTEK UNITS
Use a 5mm Allen Key on the terminal screws (nuts) and tighten to 8 Nm/71 lb-in of torque (see Figure 2 on page 6 of the CTEK Manual). Tightening by hand is not good enough, as the connector plates and cables will come loose.
The unit itself can be secured using M4 or ST4.2 screws or bolts, in each of the four corners. The screw or bolt is torqued to 2 Nm/18 lb-in (see Figure 1 on page 6 of the CTEK Manual).

FUSES
Three factors seem to come into play when determining the torque settings; the fuse holder, the fuse type and the stud size (for MIDI and MEGA fuses). Read any instructions and follow any recommended torque settings if provided. Otherwise read on.
Z CASE FUSE NUTS ON 5 AND 7 STUD BUSBARS USED ON MAIN AND AUX BATTERY
Note: the busbars used on the INEOS can have M6, M8 and M10 stud size. Both the 5 stud and 7 stud versions have a mixture of stud sizes, depending on the circuit rating. The higher the circuit rating the bigger the stud. You must work out the stud size and torque accordingly. The busbars can vary between models, so you need to look at each stud size before you torque them down.
In summary the torque settings are:

M6 studs
No torque setting is given for the M6 studs in the busbar manual. However, the
ZCASE MEGA fuse Manual gives a torque setting for M6 studs: 9.8Nm±1.4Nm or 8.4Nm to 11.2Nm.

M8 studs
Studs that are M8 can be torqued to
14Nm±2Nm, or 12 to 16Nm. However, the ZCASE® FHZ Series busbar manual states that the M8 Mounting Torque is 12-15Nm (a slight variation). Both agree between 12 to 15Nm.
FHZ manual here. Relevant extract here:

Warning: these are the suggested torque settings for the Littelfuse busbars with M8 studs and Z Case fuses used in the INEOS Grenadier.
M10 studs
16Nm±2Nm or 14Nm to 18Nm for M10 studs. Source:
Littelfuse FHZ Instruction Sheet here (page 2).
Additional information: t
he ZCASE MEGA Fuse manual states: “The fuse design is optimized for a one bolt connection M6 (40A - 250A) or M8 (300A - 600A) and can used directly on a battery post or busbar connection.” Suggesting you do not need any M10 stud even tough the busbar can be fitted with one.
Tip: the torque setting appropriate for fuses can depend on what fuse holder they are being installed into. First check the manual/instructions guide for any suggested torque settings for that fuse holder and fuse.
