Help I'm doing timing belt on 200 tdi today and need an angle figure to use to set the tension on the belt, my haynes manual says to use a dial type torque wrench but I have a clicktype and a degree disk dial gauge....any info on this would be great

the other sort of torque wrench is what you need, though, since it applies a steady torque. The angle gauge is not the same thing, that's for angle-tightening.
You can get 'em quite cheap; I think mine (average Draper) was about 15 quid. and it comes in handy for other things.
You need the "torsion bar" type torque wrench as you need to maintian a fixed torque when tightening, its not an angle thing. Any motor parts place will have one - massive accuracy is not required, so no great expense should be necesary.

I have had a few torsion bar type ones over the years ...last one got badly bent where the square drive joins the body whilst doing an emergency cylinderhead gasket job...thing is i'm sure i've seen somewhere a degree setting to equal the torque one in the haynes manual ta for feedback tho guys...Steve
OK, at the risk of sounding daft...
I have just taken my 200tdi belt off to get to the gaskets behing the timing case (another story...)
Before I removed the belt I twisted the longest section of the belt (between the crankshaft and camshaft) to get a mental note of the tension (just over 1/4" twist).
Now I havent put the thing back together yet but, not having one of these "different" torquey things couldnt I adjust the idler until I get the desired "twist", turn the crank around twice (as per worksop manual / Haynes) and re-adjust and hey presto???
How excact does the tension need to be? Granted Ive never done a tdi before but I have done my old VW Polo a couple of times (Petrol) and my Diesel Citroen in this way, nothings gone bang yet???
Is this a sure road to diaster (and £££'s) for a tdi?

Go and spend 10 quid on a pointer type torque wrench and do it properly
- the twist method is basically useless. If it all goes pear shaped you're in for big money, and you'll feel pretty stupid if it all happened because you were too tight to buy a cheap tool.
I guess your right.
Halfords here i come...
I tried halfords today in edinburgh and they said that they had stopped stocking that sort...had a fine selection of click type ones though...guess they think no one does their own timing belts even though they sell the belts...bah! S
must admit in the end i couldnt be arsed to trek to the nearest Halfords and instead went to the local boy racer car shop on the off chance.
They had one, used it last night - Must say i am a convert. The little 1/2" square hole to put the drive makes the job a doddle.
Must say though I havent had it running again yet!

Draper do the pointer-type torque wrenches.
