5VZ-FE timing belt

Your owner's manual will tell you how often. The belt on the 4.7 V8 only needs to be changed every 90,000. Yes, pretty much the entire front comes off... 2.5 hours sounds a little light. 6 is probably more like it. If they're quoting 2.5, make sure that they are replacing the TIMING belt and not the serpentine belt, and ask for the old parts.

While they're in there, it is a very good idea to replace the water pump.

That sounds about right for things to take off, however, you wouldn't completely remove the compressor and PS pump, just unbolt them and set them to the side. I'd recommend pulling the radiator to give you more working room. I got so I could change a timing belt and water pump in a 3VZE in about 4 hrs or so w/o air or a garage, but my first time was an all day affair. I'm sure a mechanic doing it all the time could do it in 2.5 hrs. You should be able to go 90K on that engine before a change. 60K is overkill, but consult your owner's manual to be sure.

I just had the water pump and timing belt replaced on my Tacoma 3.4L V6. It took the dealer about 2 1/2 to 3 hours.
