Evans also has a new line of water pumps, including one for the Cobra engine. Its shown at left, with a stock Ford pump at right. The high-flow, cast-aluminum impeller on the Evans pump certainly looks as though it will move coolant, while its larger, 3/4-inch-diameter bearing better withstands high-rpm use. An air bleed is also supplied, for easy burping of the cooling system. Another cooling-system improvement was gutting the thermostat and modifying the thermostat housing to improve coolant flow.
