I have a 1994 3.1 litre Turbo diesel trooper that has reached the 120k miles mark and needs a timing belt change. So I phoned up a couple garages and most quoted Euro 300 or so. But one said that he would recommend changing not only the belt but also the belt guides and belt tensioners or else they would not give any guarantee with the work. But the extra tensioner and guide replacement costs another 300 euros on top-total 600!
Has anybody ever bothered to replace the guide and tensioner or is it even worthwhile for the price.
Thanks in advance for your help/advice
