[align=left]I was just wondering if anyone else had problems with overheating on their mule. If you have any suggestions I would appreciate it. I've checked coolant and electric fan seems to be working properly. This is the second mule i've had problems with overheating, is this a common problem.

Common problem with all liquid cooled gasoline mules. People open the cap under the seat which is higher than both the engine and radiator and get air in the system. The trapped air gets to the light temp sender and trapped air gets hotter than water and causes the light to indicate hotter than actual temps. Take a floor jack or drive up on ramps to elevate the radiator to the highest of all points. Make sure the unit(and radiator) is cool. SET PARKING BRAKE! Remove the cap at the front of the unit on radiator. Crank unit and let it run or fast idle with something on the accelerator pedal. Let the unit run until the coolant gets hot. Keep the level of the coolant topped off to the neck of the radiator. IT TAKES A LONG TIME FOR THIS MULE TO GET HOT ENOUGH FOR THE FAN TO COME ON! Once the air is purged from the system cap it off at the radiator. Fill the coolant reservoir bottle,and stay out of the other cap under the seat. If the unit continues to over heat there is several problems to consider. Faulty fan switch on the right lower of the radiator. Faulty water pump impeller, or faulty temp switch.
Hope this helps.
