Yeah it's a 195 the Flo is good. the upper hose is boiling hot and lower is cold and if you take off the lower hose and put a bucket under it full of coolant it will suck up coolant.i have flushed it and vacuum filled the system i am lost everything works if you stay off the highway.soon as you get above 2200 rpm it will climb Temp
