Good day to all my son has a 2015 ram 2500 power wagon. Noticed fluid leaking from overflow tube after driving. So for a few days now he has been monitoring it. After driving for a while when he shut her off the overflow bottle immediately fills up then overflows. All is normal when driving but the odd time the temp jumps 5 to 10 degrees but it does this intermittently. there seems to be no pressure in hoses to rad at times either. My question is what could cause the back purge when turning truck off. I assume the t stat could be stuck not functioning properly. Is it possible that the cooling system has an air lock somewhere. If it was air lock what would get the air out. Just not sure off direction to go. Info on truck. 3 years ago the hemi ate a couple of rollers and the engine was redone. It had a new water pump installed. New thermostat installed. Complete new coolant replaced. coolant system parts were hose flushed while engine was removed. Any suggestions would be helpful. I am leaning towards thermostat but not 100% sure.
