2000 Isuzu Rodeo • 160,000 miles

Hello, I have a 2000 Isuzu Rodeo V6 3.2L Automatic, I am trying to replace the thermostat but I have to idea of where it could be, or and how to access it, I already tried to remove the radiator but I could get to the thermostat, it seems to be located under the intake but I am not sure, I hope that I wont have to remove manifold and disconnect gas pipes, thank you for your help.

3.2L & 3.5L Engines
Disconnect the negative battery cable.
Drain engine coolant from the radiator and engine.
Disconnect radiator hose from the inlet pipe.
Remove the thermostat housing, then remove the thermostat (2).

To install: Install the thermostat into the outlet pipe (4) making sure that the air hole is in the up position.
Install thermostat housing and tighten the bolts to 18 ft. Lbs. (25 Nm).
Attach the radiator hose to the inlet pipe.
Refill the engine with the proper type and amount of coolant.
Connect the negative battery cable.
Start engine and check for coolant leakage.

Thank you for your fast answer, however I already know all the steps that needs to be taken to change a thermostat, the thing that I was asking is where is the thermostat located on an Izusu Rodeo 2000 V6 L3.2 and do I need to take my manifold apart?

If you follow the lower radiator hose, you would come to the housing.
