Well I flushed my coolant a week after purchasing my 07 Commander replaced both upper and lower radiator hoses, thermostat then filled it with coolant from the dealer and followed the full procedures. For some reason every now and then it starts to get got but not all the time. Coolant level hasn't changed in over a week. To me this appears to be a flow issue but the pump appears fine. I opened the radiator cap and level seemed low. This appears to be the pump any other ideas?
