It has been two months since I've had this wolverine. I have added 20oz. of coolant to it. That is in addition to what they put in it from the factory/dealership before I bought it. Never noticed any leaking or nothing. But like right now the coolant level is on the low side, the engine is cold. I guess i want it to stay in the middle somewhere, but it fluctuates with the engine temp i understand but, it seems like it is lower than it was the other day, like closer to the low level mark. Seems like you would get to a point where you would stop having to add since it is a closed loop and all??? Does anyone else notice this? I figured there was air pockets in the coolant system when i got it and they were working there way out so i added a few ounces but it seems like i keep adding but in all I've only added 20 oz. Does this sound like a problem? Or am I being paranoid? Someone that understands coolant systems well; help point me in the right direction please.
