Bad theromostat 3.2 isuzu how to

The thermostat on the 2001 Isuzu Rodeo 3.2L v6 is located on the top of the engine under the upper intake manifold. In order to replace it you will have to depressurize the fuel system by running the engine with the fuel pump fuze removed until the engine dies and then carefully remove the fuel rail and injectors. Then remove the intake manifold which will give you access to the coolant nozzle fixture attached to the top of the engine. The thermostat is in the top of the engine block under the nozzle fixture. Be sure to replace the thermostat with the proper replacement part (may be difficult to find) and put on new gaskets for the intake manifold before replacing it.
