Hello. New to this forum and have been searching to no avail. I am wanting to get everything together to replace the timing belt and water pump and am looking for a DIY thread. Hoping for something that will make the task a little easier that I can use along with FSM.

Looking to replace belt and idler pulley set. What else should I replace while I am there? Any special tools needed? Should radiator be removed for easier access?

Thanks for any inut!

will need a tool to hold the crank pulley can be made out of a simple 2x4

Is the e-bay kit good quality? I know some stuff ther is OK and some is not. What is the black piece on the brown box near the center of the photo?

Black piece is the belt tensioner. I used a chain wrench instead of trying to fabricate the special tool. Just wrapped it around pulley. Also you will need a press for that belt tensioner. I would remove radiator just for the extra room. It is simple to remove and just piece of mind that nothing you are working on can lead to a hole in the radiator lol.

I have a 20 ton press n the garage (needed it for trans overhaul in Ram last summer) so I should be good there.

How difficult is it to keep cams from moving out of time during this change? Only dual cam I ever did was a Jaguar with a chain several years ago.

No need for a press or vise if using a new hydraulic timing belt tensioner....they come with a grenade pin installed that is removed at a certain point in the install process.

The eBay kit Elton posted is the same brands you will find in the Toyota boxes from the dealer. If you want to see more Toyota packaging and spent more $$ buy this kit from the same vendor:

The crank bolt is spec'd as non-reusable in the FSM. Buy one from your local dealer.

The crank bolt torque spec is 217 ft-lbs and you must hold the crank stable with a tool so you get an accurate torque. Bad things will happen if you don't get the torque right.

The crank holding tool I use:
The link below (see post #14). It works great holding both the crank and cam. I used a 4' piece of metal and hacked off 1' to make up the short leg.

Thanks. I really appreciate any input. I did a search but was not successful in finding what I needed to know. I knew it had to be a topic on here somewhere...

My son just pointed me to this site. I just want to make sure I have everythingtogether for this - as I will most likely go over to his shouse (about 200 miles away) so I can make him help me with it! I've never done one of these and he is always doing something on his tacoma. He'll probably give me a rash (again) because I don't do in off roading!

Search can be picky with terms sometimes.
Good luck!

That http://www.nwtoys.com/forum/tech-art...ming-belt.html link is awesome. I wish I had found that when I did my timing belt.

I'm going to update my write-up http://home.centurytel.net/stevenjac...lt/timing.html with some of that "nwtoys" information.

Skjos,

That TB writeup should be as helpful as the one you did for the tranny pan drop and flush. Thanks to it, my tranny shifts like butter to this day.

Make sure you get the service bolts in there before removing. Also their are alignment dots on firewall side of cams. The fsm explains this very well. It is actually fairly easy.

The cams may move a bit, but just line up the mark up on the cam pulley with the backing plate and the cams are in time. For the crank, there is a mark on the crank timing gear that lines up with a mark on the oil pump.

There is no need to remove the cams to do a timing belt change.....the service bolts are key if removing the cams to replace the heads or for a head gasket repair.

I'm glad to hear the write-ups are helping people out. I put them together so I can remember how to do it next time, and to pay-back the yotatech community for helping to get me through the process the first time.
