grab hold of the upper radiator hose, and follow it back to the engine block. The housing the hose is attatched is where the thermostat is hiding :)

Toyota paint codes are can usually be found either under the hood or on the passenger/drivers side door jamb. Most Toyota paint codes are 3 digits long.
If you can't find your color code on the car your local Toyota dealership (parts department) will be able to tell you your code from your registration or chasis number...
Good luck..i hope this helps, please rate me a fixya.

vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

It should just unbolt. The problem is those tend to get frozen to the exhaust manifold, especially the higher mileage ones. Once you get it of, let it set in carb cleaner for awhile. If you have a flexable wire gun stock type brush, this will help aid you in this. You might even try a local machine shop for the carb solvent if you do not have any.
