Got new belt in place, tried to move the belt tensioner with 24mm ring spanner clockwise direction. The tensioner only moved about 5mm. I assume the mechanism is ceased or broken.

I have searched the net for a procedure to replace it. No joy.
Can anyone give me a guide as to the replacement procedure. It looks as if the engine has to be dropped??

Any help will be much appreciated.

Hi Mike.
The auxiliary belt is a five ribbed belt, only fit a decent belt such as gates below.

You need to get some leverage on the tensioner nut maybe use an aviation spanner as they are longer so more leverage.

peel back the wheel arch liner you get more access that way in my opinion.

Fit the spanner as far left as possible so you get good leverage.

I would check and change the compressor belt as well at the same time as that belt seems to crack wear more that the large belt.

Note the compressor belt cracking

So it looks like you need to get more leverage on the tensioner.

Mike is the spanner moving but not pulling the tensioner back? If so then you need to get a spanner on the nut at the back and tighten it up - it is a left hand thread.
