    Greetings, I’m new to this sight. I was given an 2001 Tundra RWD from Florida with 189,000 miles on it, I just had to pick it up and drive it back to New England. Owner said that the timing belt was never changed. I prayed all the way home that it wouldn’t break. Thank God it made it.
    I ordered an AISIN kit for $185. free shipping from EBay. I was surprised the kit didn’t come with a thermostat housing gasket.
    To my amazement the old belt was in decent shape with no markings on it. Is that normal? I was told dropping the Air Compressor was necessary, it isn’t. You don’t need to remove the back bolt. I was also told you need to drop the power steering pump, you don’t. You just need to remove bolts and slide it forward enough to slide the alternator off. I’m very happy with AISIN parts and the job wasn’t as difficult as I thought it would be.

    Nice job and feedback. You have the V8? Post up pics of the truck and repair if you have them.

    Greetings and welcome. Just had mine done a week ago. Belt looked very good. The consensus is that very few t belts have actually broken. It is an interference engine though. My change intervals were 87k, then went another 190K before changing last time. My best friend has an '03 Sequoia he bought new..... 415K+ miles and original belt.... I wouldn't do that. But like I said, my belt with 190 K on it looked great... it was just a lot flimsier.

    I've had a belt go over 160k and saw no cracking, but that doesn't mean the belt hasn't stretched or that the tensioners haven't worn out. So I would limit any belt to double the life expectancy and make sure I change it then.

    As for removing the air compressor, I leave it on to, I just loosen the back bolt to relieve any tension on mating parts. As for the steering pump I leave one bolt partially in and just swing the pump out of the way.

    I changed the timing belt on my wife'03 4runner with the 4.7 v8 . I inspected the belt and 2 of the grooves we're scarred up pretty bad.The thing about timing belts are you don't really know until you check them. I have changed my 2000 tundra timing belt 3 times now and they all looked good.It just takes one broken or slipped belt to end up buying another engine!!

    Thanks for your feedback guys. I didn’t want to take any chances either. $200.and my labor is a lot cheaper than searching for an engine or junking truck.

    Question, is the normal oil pressure gauge reading at idle right around 1/4 and at acceleration just over 1/2?
    Having just replaced the timing belt and getting it back on the road I never really paid that close attention to the gauge before but thought it was higher.
    Thank you.

    This is a normal question on the 1st Gen Tundras. Yes is the answer. These engines spike that gauge.

    Agreed, at idle the oil pressure is about 15 lbs, and maybe 30 at running speed. The pressure will change somewhat depending on the weight of oil you use or how dirty you let the oil get, but I don't think I have ever seen my pressure gauge get all the way to the mid point.
