NO! Stock thermostat is very different than I have seen (I would not expect it to be cheap or easily available) and the worst part is the ENTIRE intake manifold has to be removed to replace it. Has yours failed? Coolant leaking under the intake manifold is more often than not,(especially when it is intermittant) the water manifold's o-rings and those CAN be replaced without removing the intake. Do a search for manifold and you should find Ron's same issue - I have replaced my orings twice on that part.
