What is the best tempeture to run a 3208 engine?
Engine water temps are a result of friction of operation and the
ability to cool. Any one factor in the equation will change the operation temp. To keep the water cool does not mean that you have reduced the engine stress. if you over build the cooling ability you lose the temp stress gauge. Engine oil temp is closer to a gauge of friction stress. but engine oil is effected also by water temp. When I make a hill climb. I always down shift and find a range where I can maintain a higher rpm but have the ability to move the bus faster by dumping more fuel. This tells me I am running the bus with less stress that the maximum engineered . It is quite possible to overheat an engine on a long down hill run with engine backpressure and over the limit rpm. I find a down hill comfort zone there I can relax knowing if the little 12 volt wire that is keeping my tranny in drive fails I can still use my brakes independent of any jake, driveline, exhaust, or trans relarder. Down hill is a chance for the fleetwoods to catch up. Its shamefull that he can return tuesday to 'good news' that it is not a $20K repair but simply a $6,500.00 head gasket job. I had a government fund letter requesting over $100,000 for underpayment of club dues. After a review by a private mathmatician, he said, "I have good news, you only owe $17,800.00",,, no relief was experienced.
