Whatever you think about your local dealer, if you have ANY doubts that you might not be able to do that t-belt correctly, then it'd be my opinion to just bite the bullit and pay them as if you botch it, it'll really run about $3,500 US to repair the damage. It's your car so the discision is yours but despite the fact that Bay13 posts those instructions, it's my honest opinion that not everyone should attempt that if they're not familiar with similar engine repairs. You will read where people here and elsewhere will say "peace of cake" but then I've also read stories of costly, time consuming disasters and all because a guy thought the job would be far easier than it apparently was for that particular person.
