Just wondering what kind of thermostat you are running in a 22r. 180 or 190. I have a 18 or 20 foot dolphin with a 22r. I just did lots of motor work and when I drive on the freeway it wants to heat up past the center of gauge not enough it over heat but it gets lots hotter than my 22r in the crawler with 39s. When I took the motor apart I noticed it did not have a thermostat at all. i just changed the water pump, thermostat, all hoses and head gasket flushed the radiator a few times and had the head checked. I have probably put one take of gas since I fixed it and it runs great other wise. any ides do I need a new bigger radiator, Flex light or ????
Thanks
Tom
