Is there any truth to the rumor, I was just told, that two different size water pumps were used in this engine? Possibly I was installed with the wrong size at cost of 151 USD to the effect of 215 deg idling temperature. I would hope to get the right stuff from an authorized repair facility. I just recently got my favorite restaurant to keep the snails off the food. I don't believe I have damaged the motor yet because I caught it in time and have not been using it, though it took ten days to get an infrared thermometer. A lot of good reasons to fix things your self.
