kaya5150 Posted November 12, 2007 Share Posted November 12, 2007 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 Quote Link to comment Share on other sites More sharing options...

If it is still warming up on the hills then back the timing down 2* at a time until it's running at normal temp. Quote Link to comment Share on other sites More sharing options...
kaya5150 Posted November 22, 2007 Author Share Posted November 22, 2007 Got it fixed! I took out the thermostat and it still got hot turns out my clutch on my fan was bad so I just welded it together and it works great now. I think I will order a flex light but I just drove 70 miles and never even can close to the center of the heat gauge. right at 180 happy thanksgiving Quote Link to comment Share on other sites More sharing options...
