Just about to change timing belt on my 2012 sd4 can anybody give me the torque settings for crank pulley, idler and tensioner please.

Sorry, not the sort of thing I keep in my memory.
I'd have to go and search for it.

Have you got the freebie JLR workshop manual ? Jules

The torque settings are here.



You're best bet is to follow the LR belt replacement instructions. You'll need the timing/locking tools, and a full belt kit which should come with the water pump and a new pulley bolt.
I'm sure the Gates kit contains everything you need, including fitting information. Hyundai Ioniq 5 Ultimate. The family car.
2009 Rimini Red SE TD4. Gone.
2006 Tonga Green i6 HSE. Gone.
Audi A5 convertible, my daily driver.
1972 Hillman Avenger GT, the project.

As above

Serpentine belt tensioner 35ft lbs 48 nm
Serpentine idler 35 ft lbs 48 nm

Timing belt tensioner 25 nm
Timing idler bearing 60 nm

Water pump 17 nm

Crankshaft position sensor 7 nm

Crankshaft bolt torque 52 ft lbs 70nm + 60* degrees (using torque angle gauge)
