The service manual that came with my vehicle recommends replacing the timing belt at 90,000 miles. It has a note at the bottom of the page though that this is for the 2uz-fe engine only. Apparently that's the 4.7 L, mine is the 5.7 L. I'm not a car guy so didn't really understand the difference between the timing belt and chain and such. Anyway I went to my mechanic and showed him the service manual and asked him how much it would cost to do all the required maintenance.
He looked at it carefully and even asked me what type of engine mine was (whether or not it was the 4.7 L, etc).
He then said the timing belt was really hard to replace labor wise and that was like 10 hours. He said if the manual said it should be replaced then i definitely should or else the engine could get damaged.
I think he said all this in good faith.
However, then he called to get a quote on the parts and I heard something mentioned about a chain.
So ... then he quotes me $850 to do the job. I'm reading online and finding out that apparently a chain doesn't need to be replaced when the belt does as the chains are designed to last longer.
So what I'm hearing is that this isn't necessary, is that right? Should I feel like he tried to rip me off? Does the chain ever need to be replaced - any idea when?
