I'm going to do a change of cams and lifters soon (as i've got one or two sticking), and I was thinking of refitting the existing belts as both were replaced 5000 miles ago.

What belt tension should I use?, do I set the tensioner as I would a new belt?

Also the best i've had fuel economy wise is 23 - 24.5 mpg, and that's on a motorway run!  I've tried all the cleaning additives for fuel, put shell UL and optimax in,  - any other suggestions?

NO!! replace belt and tensioner once removed!!

[KillerWatt]

As above, do NOT refit the old kit.....replace with new.

that's made it one hell of an expensive cambelt!

[Lazydocker]

I'd say that the tensioner could be re-used but fit a new belt. It's the bearings that give up on the tensioner.

Or leave the cam change to the next time the belt is due

if the belt looks ok with no cracking or crazing then no need to replace as long as you know that the belt and tensioners were only replaced 5000miles ago.

Belt tension should be set on the mark rather than above it as you do when new  (hope i've got that the right way round - need to check the cambelt dvd but can't find it sorry :-/)

I don't think our's (2.5 CDX Estate Auto) does much better to be honest, although I am quite heavy footed.

The computer will report 40mpg (instantaneous consumption) at 60mph on a run, but I don't believe that for a minute.
I'm off down to Pompey again tomorrow, so I'll report back then what I can screw out of it if I drive it like a tart (tart driving = 60mph in the middle lane with my nose 2 inches from the steering wheel  )

I personally can't see why you cant refit the belt and tensioners if you know they have only done 5000 miles...
As already said put to the other mark

23-24 mpg on a run out of a 2.5? you are either foot down then, towing something or you have a problem..
I have a 3.0 auto fully loaded with camping gear, roofbox with four people in and got 32 going on holiday sitting at 70mph.... I got 29 mpg going to Dumfries sitting at 85-90......

I pretty certain as it was me that done the replacing   !

All part of my big mig diary thread!

In which case I personally would have said you will be ok then

I drive mine like an old maid since the lifter started making a racket, so I think that I do have a problem

I agree! Perfectly acceptable to put it back on after only 5000 miles.

i find it very hard to keep the 3litre at 70 it seems much happier at 100+  

maybe thats why £50 lasted me 130 odd miles

Just as happy at 95, and you will be too when the Plod pull you
