Change the water pump while in there and the tensioner, you could run a long tap down the threads around water pump as they could get corroded up, change any iffy looking bolts for new too.
I didn’t use the a beam torque wrench I guess as you use it to tension belt with a click type it’s clicks and you lose it, so need to guesstimate the tension or add a touch on the torque first and use feel and new quality seals

A beam type torque wrench are about £40 on Ebay, just buy one, after all you have saved loads of money on labour. As mentioned above you need to hold the tension, not do it up to a certain tension.
Change the crank and camshaft seal if leaking.
Replace the timing case cover bolts for new ones, I used cap heads.
I wouldn't bother changing the water pump but might aswell fit new belts while they are off.
Ours was a Disco 200tdi and it was a struggle getting the belt tensioner on, it's amazing how much the belt stretches after a few rotations of the engine.

It is bot of an art tensioning the cambelt, you can and I do do it by hand/eye, but as the belt is quite a bit wider than normal car cambelts it takes some judgement.
Other thing to remember is to try and get the inj pump adjustment slots in the middle of their travel to allow for later adjustment if needed.

Belt does not stretch, merely settles into its correct operating place, hence why they say turn it over a couple of times by hand.

Ok, why is it easy to get the tensioner on with a used belt then?

Belt has settled and worn some.

I doubt that being only a couple of months old.
Anyway, I am no expert. Just pointing out it was awkward to fit the tensioner with a brand new belt but easy with one a couple of months old. The conclusion I came to was they must stretch a bit. Both were Dayco belts with the same part number.

Not worn as in stretched but teeth have bedded in.
If you think about if, if a timing belt stretched it would not be doing its job.
I have always found 200 belts a sod to fit when new and with a new tens, almost like there is zero tolerance.

I have been thinking about it and you are correct, "stretch" may well be the wrong word.
Newer kit has auto tensioners, so things must wear and whats older motors cambelts get slack, think my d3 cambelt has an auto tensioner, I should remember as have done the belt twice!
Was an old wives tale when cambelts were a new thing that they were rubber belts/terrible idea etc etc, then ford invented the wet belt and it sort of came true
