I should be along the bottom of the radiator. If it is the original from Toyota then there should be 3 hoses that connect along the bottom (1 large and two small), a drain plug, and wiring harness that connects to the temp sensor. Undo the harness clips and use a 3/4" wrench to back out the sensor. Some after market radiators will have a one port that doubles as the drain and temp. sensor location. Just follow the wires down the right side of the fans and along the bottom of the radiator and you will find it. Of course you will have to drain and remove the radiator to do this. At least that how you do it my '00 Solara w/ a 2.2L 4-cylinder. It may be different on a 6-cylinder, but I am not sure.
