That is what the valve is used for. 100 degrees is too cold. Most people set to 160-180 at cruise. When you adjust, do it in small increments(1/8 to 1/4 turn). You might also want to look into a thermostat system. CP Performance sells them. DO NOT use an automotive setup!www.cpperformance.com (http://www.cpperformance.com)
