need to replace squeaky twin belts on my 05 warrior I've adjusted them twice now but must be stretched as they squeak and go slack soon.
any tips ? seems like need to remove a lot of other drive belts first to get to them.

What truck u got mate?

its a 05 warrior double cab 2.5 diesel

You need to loosen off the pas pump. There are bolts that can be accessed through holes in the pulley and at the bottom of the pump. Once loosened you should be able to pull the belt clear and remove it over the fan.
Alternator can then be loosened. One main 14mm bolt holding it to the block, and the 12mm bolts on the tensioner. Once loosened the belts should be removed over the fan again. Sometimes it is better to drop the skid plates to get better access to the alternator bolts.

Thanks Rob, just thinking when I adjusted the belts I only undone one m12 locking bolt near to the m12 adjusting rod I never seen this m14 bolt maybe this is loose and letting the belts slacken off.
Is this m14 under the alternator ?

It's the bolt that attaches the alternator to the engine. The alternator pivots around it. I've adjusted it without undoing it before but have ended up snapping the tension bolt...

Thanks mate, will be doing the job tonight so just as well you pointed it out or I could have done the same
cheers H
