Just as easy, but a bit messier. Gotta drain the coolant , remove the thermostat housing, remove the thermostat, make sure the old gasket is removed completely from the intake manifold and the thermostat housing (scrape both manifold and housing CLEAN), install a new gasket, a new 195degree thermostat and re-insatlaa the old thermostat housing, then re-fill the coolant. Oh, and be sure to look at the thermostat when you take it out to be sure you know which way it faces.Dont put it in upside down!!!
Simple, really, but allow an hour, at least, for the job.
Hope that helps,
