The heigh temperatures have led to problems, such as early deterioration of the hoses and other rubberized parts. Therefore at the most convenient time, usually when the first thermostat became defective, I have replaced the high temp thermostat with a lower value one, 160 to 170 range. The motor ran better, parts lasted longer, etc. It probobly was less efficient and more polluting, but I was unable to detect it. Anyway, you could probobly do the same thing with your new car and have the same satisfactory results. -- Albert H. Spinks - 71BU072120
