Good Morning having a few issues with my new-to-me 2003 6x4 Gator. Its overheating after driving it a short distance. A good friend helped me with it yesterday, and we were able to answer a few questions, but now seems to be even more puzzled? So, here goes... The Gator's red temp light on the dash comes on after its been driven just a short while. I replaced the lower radiator hose a few weeks ago (it had split open) and not certain if I now have an air gap in the system or just what is going on? This is what I do know, The radiator is filled as is the overflow tank. I've driven it over bumpy terrain in an attempt to move any air pockets. Yesterday we pulled the upper radiator hose by the carb and found there wasn't a thermostat. Huh? Now have a new one for it. Removed the small hose that carries water from one side (by carb) to side by water pump. When we did this it did seem like there was air in the line as it "poofed" and splattered a little antifreeze when it came off. Pulled the 12mm bolt by the carb and poured water in while engine was running. Both upper and lower radiator hoses are warm, so I believe water is circulating. Don't know if the fan is coming on or not? Is there a way to test the fan by jumping from the battery? Also wondered if maybe its a faulty wiring issue causing the light on the dash? Found antifreeze on the concrete slab it is parked on and have no idea where its coming from. Any guidance is greatly appreciated!
