If it's the springloaded tensioner, then there's a locating dowel on the back of it. That just locates onto the housing and the bolt (or bolts, can't remeber if there are 2) just do up. The use a spanner to pull back the spring loaded tensioner when you put the belt back on.

The other tensioer is just three bolts on the front of the timing cover.

thanks guys he just figured it out, i came back on to say we've sorted it and read the post on how to do it, thanks again gotta dash before he does something else to the car

As others have said, the auto tensioner has a small dowel on the back of it, will slide straight it when at the correct angle. Make sure the belt is well out of the way so it doesn't put any pressure on it as it needs to go on straight to go back in easily.

What noises have you been trying to diagnose? If its a noisey chirping type noise from the belt area, and you suspect the tensioner, it is fairly well known that manufacturing tolerances can leave them slightly off angle, if this sounds like you, try putting a 5c coin between the back of the tensioner and the engine at about the 9o'clock position and tighten back up. After 2 new belts of different brands and much frustration, it has worked perfectly for me. And way cheaper than a new tensioner

Good luck with it!
