Does a 2000 Nissan Maxima 3.0 have two thermostats?

Yes and no. Yes, there are two 'thermostats' on the vehicle, but only one is the main thermostat that controls the engine coolant temperature. This main thermostat is located at the front of the engine block and is built in to a water inlet housing that connects to the lower radiator hose. If you're doing preventative maintenance on the cooling system, THIS is the thermostat you'll want to replace. The other part that looks very much like a thermostat and is often confused with the main thermostat, is actually called a "water control valve". This water control valve is located at the rear of the engine block. This part doesn't really control the engine coolant temperature, and does not require periodic replacement like the main thermostat.
