You didn't mention your engine, but the tbelts on these things are pretty
straight forward. Both engines are non-interference, so if you screw up
you've done nothing but cost yourself more time. And like ray said, the
online Toyota thing he posted a link for is the same thing I use at work
every day, and probably the best for step-by-step mehcanical processes. I
think the diagnostic guides in the FRMs stink, but you won't be using it
for that. GIve it a shot, and if you get stuck throw up a flag here and
we'll help you out.
I have a 6' high box full of tools that get used on other projects as well
as stuff that rarely, if ever get used. When I work on Ford and GM
products, I need to get out a much larger assortment of wrenches.
I recently replaced the timing belt on a Camry, my second. The hardest
part to me was removing the bolt from the driveshaft but I found the
right size socket and used my impact wrench, came off easy but the first
time was a pain. I would suggest using some white paint to put marks on
the gear teeth wheels/old timing belt then after you remove the old
belt, transfer the marks to the new one so it'll go back exactly in the
same spot. I would also replace the water pump, idler pulley and the
spring that goes on it. I like to use OEM parts for this job. The next
most difficult job for a first timer is to set the tension correctly on
the idler pulley. The book tells how to do that but I insert a 24 inch
rubber hose in the #1 plug hole for two reasons when rotating the crank
to set the tension. You can tell when you're on the exhaust stroke from
the air coming out and you can tell when you hit TDC when the hose comes
up to the top. I'm talking about a hose that just barely clears the
plug opening. You then have to continue the rotation about 90 degrees
or so to lock the idler down. Also, if you do replace the water pump be
sure to not overtighten the pump bolts. I personally use a 1/4" torque
wrench as those are easy to overtighten and break off. The job is not
hard but I like to use an air impact wrench to take things off. I don't
use it to put them back. Also, don't make my first mistake and try to
tackle this job in the middle of the winter under the carport. I've had
good luck with all the timing belts I've replaced but on the Camry you
need to really pay attention to the pulley tensioning. Too loose and
the belt will tap the plastic covering when idling and too tight and
you'll damage those bearings on the water pump/idler pulley. I forgot
to say that the water pump is driven by the timing belt. Good luck.
