An engine cooling system includes a coolant circuit, a multi-way valve, a relief route and a relief valve. The coolant circuit includes a first route and a second route into which the coolant circuit is branched off at a branched position. The first route passes through a radiator. The multi-way valve is provided at the branched position. The relief route sets a relief source to a portion downstream of a pump and upstream of the multi-way valve in the coolant circuit, sets a relief destination to a portion downstream of the radiator in the first route, and causes coolant to flow from the relief source to the relief destination so as to bypass the multi-way valve. The relief valve interrupts circulation of coolant through the relief route when the relief valve is closed, and permits circulation of coolant through the relief route when the relief valve is open. 1. An engine cooling system comprising:a coolant circuit through which coolant flows from a pump, passes through an inside of an engine and returns to the pump, the coolant circuit including a first route and a second route into which the coolant circuit is branched off at a branched position downstream of the inside of the engine, each of the first route and the second route being connected to the pump, the first route being a radiator route that passes through a radiator;a multi-way valve that is provided at the branched position at which the coolant circuit is branched off into the first route and the second route and that is able to vary a flow rate ratio of coolant flowing into each of the first and second routes;a relief route that sets a relief source to a portion downstream of the pump and upstream of the multi-way valve in the coolant circuit, that sets a relief destination to a portion downstream of the multi-way valve and upstream of the pump in the coolant circuit, and that causes coolant to flow from the relief source to the relief destination so as to bypass the multi-way valve; anda relief valve ...
