On the passenger side of the intake manifold, coming off the bottom about the center of the engine front to back, you'll feel a hose that comes off a nipple. That hose makes a 90 degree bend and goes around to the rear of the motor. Where that hose meets the Y-connector from the other side of the intake you'll find the PCV valve. It's almost impossible to see it with the hood installed, and even tougher to reach it.
Find the location where the upper radiator hose connects to
the intake manifold of the engine by tracing it from the radiator to thermostat intake housing bolted to the intake.
Remove the radiator hose from the thermostat intake housing
by loosening the band clamp that secures it into place. With the clamp
loosened, pull the hose off the housing.
Remove the two bolts that secure the housing to the intake manifold and then lift the housing off the intake.
Lift the thermostat out of the intake manifold and place the
new thermostat into the hole. The end of the thermostat with the pin
protruding from it sticks out of the intake manifold.
Lift the thermostat intake housing gasket off the intake manifold and place the new one onto the intake manifold.
Place the thermostat intake housing onto the intake manifold and bolt it into place. Reconnect the hose using the band clamp.

Allow adequate time for the radiator fluid to cool down. Thirty minutes
is usually adequate.
Loosen the petcock on the lower right hand side of the
radiator and drain all of the radiator fluid into a drain pan. Close the
petcock once drained.
Trace the lower radiator hose to the location where the hose
connects to the engine block. The metal housing the hose connects to is
the lower thermostat outlet. Remove the hose from the outlet by
loosening the band clamp and then by pulling the hose off the outlet. Be
careful--some fluid will drain from the hose.
Remove the two bolts that secure the thermostat outlet to the engine block and pull the thermostat outlet off the block.
Discard the O-ring inside the bottom edge of the thermostat outlet and place a new one into the outlet.
Pull the thermostat out of the engine block and replace it
with a new one. The end with the pin protruding from it sticks out of
the engine block.
Place the thermostat outlet onto the engine block and secure
it into place. Reattach the lower radiator hose with the band clamp.
Open the radiator filler cap located on top of the radiator
and fill the radiator with the fluid previously drained from the system.
it is down under the intake manifold. the intake manifold must be removed to get to it. this vehicle is known for developing a vacum leak in the elbow hose that connects to pcv valve, so ive done a few.
