This is a discussion thread titled "Timing belt replacement", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
Can someone tell me where this timing belt is? I see only one belt, it drives everything. Is it internal?

Fan belt=$30 and about 20 mins
Timing belt=$$$$ and about 6 hours worth of labor
PS-Congrats on the S/C though...I have major league induction envy

I have a question for all you guys who changed your own timing belt. I ordered all the parts from conicelli partznet. May I say I was very impressed with both price and delivery. One thing though, I noticed when I was going through the invoce and parts making sure what I recieved was correct, that the number on the timing belt was not the same as the the number I had ordered. Although the bag the belt came in had the correct number on it. The belt does have the three marks on it though, R cam, L cam & crank. So I am assuming that this should be the right belt. I phoned conicelli and spoke with a parts rep.He could not cross the number on the belt but the number on the bag is good. He belives this belt to be correct. What do you think guys? hate to get down there and have it be the wrong one!

If he has other belts in stock and the number printed on those belts matches yours, then relax. If not, ask if he is willing to exchange it for you.
You could also look up the specs on the belt you have and compare them with the "correct" belt.

if you havent solved this yet, check out my recent posts in this forum from my timing belt replacement, there are lists of part numbers, and i added two part numbers to the current list--it now covers (almost) all of the wear items forward of the block.
My truck has almost 143,000 miles on it and I was going to have the valves adjusted since they were going to be keeping for a couple of days anyway for the timing belt & water pump. The Toyota dealer stated that the valve adjustment takes 11.2 hours. Could this be possible?

That's going to be a book quote. You have to watch them, because they'll nail you on labor charges. Pretty much anything that involves pulling the front end apart is going to be 6-8 hours. As we all know, with the timing belt off, the water pump is another 10 minutes, and the serpentine belt a gimmie, but some have been quoted nearly double on labor when they ask to include it.
Same for the valve adjustment. It IS more involved than the belt change, as the valve covers do have to come off, but it doesn't sound right that it would be 11.2 hours in addition to the belt and water pump.
Maybe a TOTAL of 11.2 hours for the whole job.

JUST a valve lash adjustment or a complete valve job? If it's just an adjustment, methinks that number is a bit high too. You can try calling other dealers and getting additional numbers to average out your estimate.

I replaced my own timing belt at 90K, along with water pump, cam/crank seals, idlers, tensioner, thermostadt, etc. I measured the valves at the same time.
You have to remove the valve covers to do the timing belt. It only took me an additional 20 minutes to measure the valves. All were in spec.
Now if some valves needed adjustment....you have to remove the cam to replace the shim, and that could get in to some time. Certainly not 11 hours...but more like an hour or so.
But if they are all in spec.....only takes a little bit of time for the actual measurement.
I don't think you have to pull the valve covers to change the timing belt. The timing belt replacement adds a bit of labor though to the cost of a water pump replacement. The additonal labor is for pulling the crankshaft pulley, which the dealership said is not necessary when just changing the water pump.

You are right. You really don't have to pull the valve covers for the timing belt change.
You do, however, have to pull the cam pully off anyway, in order to change the cam seals. You wouldn't want to rely on your original cam (and crank) seals to last 180K. If the seal lets go, oil will quickly ruin your timing belt.
Well, I finally got my timing belt done. I did it when I got home from work in the span of two consecutive days. I gotta agree with JeffD and leadsled, not a difficult job just time consuming. The belt and all of it's components were all still in great shape, can't say the same for the water pump. That was junk. Strange thing happend though, my truck didn't start the first two attempts. It just cranked. On the third attempt it fired up and ran great. I proceded to burp the cooling system and about 45 seconds later the Check Engine Light illuminated. DOH!! My first one on my Tundra. I drove into work this morning , broke out the OTC scanner and extracted a cam sensor code, cleared it, fired the truck back up and...no more CEL. I'm hoping it stays that way. Things that make you say Hmmm.

PLEASE, someone chime in and give me your thoughts...I would gladly take photos and post the procedure, but need someone with some experience who can tell me if this is HUGE mistake or not...
I just bought a 2001 Sequoia with 118000 miles, and the timing belt had never been changed. So I changed it. After asking around, I decided that while I was at it I'd replace the water pump, timing belt tensioner, idler pulleys and serpentine belt at the same time. Parts cost about $350. Took me about eight hours to do it. I used a Haynes manual which was fairly helpful. I don't have a lot of faith in Chilton based on past experience. The only thing I wish I had known was that there are two orings associated with the water pump that I would have liked to replace. I didn't have them so I just stuck the old ones back in and haven't had any problems. Be aware that you must have a new water pump gasket if you replace the water pump. Also, Haynes recommends a new throttle body gasket. Min elooked fine so I reused it.
