I have a problem with overheating. After filling system with coolant, I can drive my normal routine for 7 to14 days before it starts to get hot. At first the temperature gauge stays at first mark[ about a quarter of gauge]. After a few days it slowly rises to middle, a few days later to three quarter, then I have to add more coolant. Water pump is new, timing belt is new, timing is ok, thermostat is new, radiator cap is new. I did a cooling system pressure check, [pumped up to 15lbs, waited 30 min, went down half lbs, pumped back up to 15lbs, waited 30 min, held pressure] and a block check[The liquid remained blue indicating no combustion gases in system] I replaced the temperature sensor because someone told me to, no change. I can see no visible leaks. The cooling fans appear to be coming on when they should. The check engine light does come on, and the code I get is po441. I think this is happening because the temp. Is not reaching normal operating temp. For fist few days of driving. At any rate, this has become very frustrating, I need help
have the same problem?
