So my water leak was a shot water pump, which will be replaced today. Cam belt looks ok, has 2 year or 30K on it which ever comes first but should I change is as it got a dose of coolant? I am tempted as the cost seems minimal for the parts, but do I need the full locking / setting kit at £100+ ? Or is that only to set the timing and a couple of Cam locking wedges will suffice?

You need the full kit. The locking wedges are the least important part of it.

Disappointing - what does the kit do? Having only ever done a 1.6 Cortina and an Omega 4 Pot.....

Belt will be fine and as a result wont need to be removed so the timing will be unaffected.

Well that is certainly easier, I did rinse the coolant off with fresh water and all look nice and dry now.

Out of interest what does the kit do though?

The locking kit basically holds all the really expensive bits in position as the belt is changed, the cambelt kit is the belt and all the pulleys etc...

The V6 has adjusters on both long sides of the belt run, and one between the cylinder heads. The timing marks are intended to be used with the kit, and not with other marks on the engine - unlike a Pinto. This gives a lot of leeway for getting the cam timing badly wrong.
The kit consists of a crank stop and gauge that enable you to set all four cams in the correct place and lock them there with the wedges. Then you fit the new belt and turn the engine through one entire cycle. You then  use the crank lock and gauge to adjust the cam timing and tension to specification. This can take several attempts, and isn't viable without the kit.

I suspect that with a lot of practice you could get it very close without, but why take the chance?

My car had clearly been done without the tools, as there were traditional Tippex marks everywhere. It was a tooth out on all four cams, which meant I had to do the job from scratch.

Thank you, that explains why its more complex than the 4 pot Omega.

I think I am going to put the new pump on for now to give me time to see if I can get the correct kit for a sensible price.

While yours is apart, look at the stamp in one of the webs on the backing plate

The Contitech belt kits from bypartsby are cheaper and you work out which kit you need from your engine number.
