I need to change the thermostat in my 98 3.0L Sienna. I can't seem to find it. Most cars have it on the block right where the top radiator hose connects, but I don't see a housing there where it would be. Anyone know?

it's at the rear of the intake manifold, you gotta remove a couple of hoses and wires to get to it, make sure you drain the coolant first.........
