2001 Dodge ram 1500 not getting up too temp.
I have a 2001 dodge ram 1500 5.2L V8 4x4 and the engine temperature
won't get up past 174ish. I replaced the thermostat with a $5 one from
rockauto, the lower radiator hose, and water pump. I also did a full coolant
flush through the block and radiator. I just recently replaced the thermostat
again with a $30 one from the dealership that is the stock oem 195 one and
still wont get up to temp. Also the upper radiator hose seems to never fill up
with liquid and feels like its always air even though it gets hot. NEED
HELP!!!
