This car was manufactured in Canada and has a lot of preheat mechanisms. For example, this foil air-intake hose draws air from next to the exhaust manifold (one of the hottest regions in the engine, even on startup).

What is shown here is the valve that switches from taking in air from over the exhaust manifold, to simply from under the hood. This is shown in the position it is in when the engine is already hot. The hose on the left with the wire-clamp is the engine's coolant intake; the upper radiator hose. Inside of the fitting this attaches to is the thermostat that blocks coolant flow until the engine is warm enough (usually 180-190°F, depending on season)
