New member From Northern Indiana . and coolant ??????

[Tarak1980]

I have a Coleman HS400UTV-5 got it manly for hunting and spending time with the grandkids

The one problem I am trying to avoid. My son borrowed it last summer and said it ran hot so he added water to it . I do not know how much he put in so I would like to drain most of it and add new coolant to protect it this winter. I can find no drain cock or any way of draining it besides loosening a hose.  Any suggestions ????

Welcome aboard..overheating is a big problem with these things. I assume it's a Hisun engine?  Loosen a hose or the temp switch on the radiator. Be sure to get all the air out when you refill it..

Exactly as Joe said. You have to loose a hose to drain, no petcock.

When you add coolant. Be sure to raise the front end. The higher the better. Then on, my axis 500 and others, there's a bleed screw/bolt on the gooseneck on the head. Where the coolant hose connects to the head. Be sure to bleed/burp all the air out. 

I recommend bleeding there multiple times. Over a course of multiple heating up cycles. 

If your son did get it hot. Once you have all the air out. Check and make sure there is no coolant in the oil. Make sure there is no bubbles rising in the overflow coolant catch jug with radiator cap on once the engine is up to operating temp.

On my axis 500, the temp sensor is on the gooseneck at the head. That sensor turns on the temp idiot light on dash.

There is also a temp sensor on the radiator. That one tells the electric fan to kick on and off. 

 

Best of luck and welcome to the forum from KY.
