Abstract
A wax motor thermostat for an engine cooling system. The thermostat includes a cylinder having at least a first wax portion and a second wax portion each configured to expand at different temperatures. A piston is movable in response to expansion of the first and second wax portions to move the wax motor thermostat from a closed position to a fully open position or a partially open position between the closed and fully open positions to allow coolant to flow through the wax motor thermostat.
