Title: A different question, HELP!
Post by: Shackeng on 17 January 2010, 15:37:40
'99 2.5td.  I can see the tensioner to be adjusted/relaxed for the water pump removal, but the front belt does not appear to have a tensioner, just an idler below the LH (from front) belt driven unit (AC compressor?). Does this idler have to come off/be adjusted?

I am reluctant to take the belt off without knowing how it is tensioned/adjusted if required. But I would like to replace it along with the main belt and water pump.

Help please guys.  :-/

take the cap off, from the centre of the tensioner,undo the 13mm nut this will slacken the belt,to put tension back on belt put a 10mm allen key in to the allen key hole and turn untill you are happy with the tension, then tighten 13mm bolt,put cap back on jobs a gud'en :y

Also make sure you get the right a/c belt,on mine it was an 4pk805.Some say theres only one but a few have had problems with the size.
4pk805=four ribbed 805mm long

Thanks again Charlie, I had eventually discovered that the tensioner sneakily had a cap on it, so have now got everything off, bar the pump pulley. However, I have a neat small puller which will do the job tomorrow.

I don't suppose that you have any torque loadings for any of the bolts involved? Always a problem without a manual. (B****r John Haynes) When I bought my car nearly new, the manual was listed as being printed that year. Then they cancelled it. Grrrrr! :y :y :y

hope this makes sense water pump to block 10nm/7.5ibf.ft.... water pump pulley to water pump 10nm......blue bolt 20nm green bolt 40nm...yellow bolt (could not find a torque value, just secure)......a/c belt tension roller via hex key new belt 5nm-6.5nm.....re-used belt 7nm-8.5nm......a/c tensioner 22nm :-/
