I have been trying to locate the thermosts on this engine along with the auxilliary water pump for the heater, would anyone know where they are located?? I could really use some good help.

See if a search in the X308 section turns up any of the usual "replacing the thermostat tower" threads. That's the type you have. It is different from the one on the supercharged motors.

Same for the auxillary water pump, search for "auxillary water pump" to find the "no heat" threads.
