hey chris, this is cody dean. i put that new water pump on and gave it a test run today. i filled the coolant up and did all the bleeding process. i drove the rhino around for about 20 minutes then parked it. about 2 hours later i checked the oil and it was merky again. so i checked the coolant level and it was about half way empty. do you think it might be a head gasket or what. maybe a craked head or cylinder?? it must be a slow leak until high rpms or something.. let me know what you think.. thanks again. call me if you have any questions. 509-727-0891.. thanks for everything
