The only thing more

The only thing more frustrating than changing a thermostat on a 2001 Rodeo/Passport is trying to find accurate information on the subject. The people who keep advising me to follow my top hose to the block in order to remove the thermo housing should quit cutting and pasting this useless info and actually open the hood on this vehicle and become acquainted with the task.

Think you’ll agree that by now the thermostat has been replaced :-) :-).

(You said) to change out the thermostat you've got to remove the intake manifold. The thermostat housing is buried beneath it.

This thread is over four years old.
Normally I wouldn’t post a response.
Only posting a response because your above statement needs correcting.

Close buddy but still not right.

In other words an “Intake Manifold” and an “Upper Intake Plenum” may perform the same function but the construction many intake manifolds can vary and be different from most others. Usually you have a single casting that has tubes (intake runners) that distribute “AF” (air fuel) from the throttle body to the intake ports on the heads. Frequently the an intake manifold can be a “Several Piece” design. In other words, the intake runners are separate tubes that sit inside the plenum and draw air from that chamber and distributes it to the intake port under vacuum. By definition a plenum is an air enclosure that has a higher pressure than the outlet (cylinders during the intake stroke). A manifold is a pipe so fitted that it has several apertures for making multiple connections. So technically we don't have a manifold. We have an intake plenum that the a/f is drawn from by individual tubes connected to the intake ports on the cylinder head.
