You say that it still over heats, meaning that you replaced the hose thinking that this was the problem ? Start from the beginning, check to make sure that the rad. is good. Does it o/heat at idle only ? electric fan work ? Does it o/heat all the time ? Change the thermostat. How old is the rad. ? Has the water pump ever been changed ? Could have poor circulation. Make, model, will help.
try a radiator cap......or you have a head gasket leak.
Try taking the thermostat out completely, then see if it still overheats. If so, your only other problem has to be a bubble in the system and it needs to be burped. Took me about an hour to get a stubborn air bubble out!
did you check the radiator or the head gasket?
check your fan clutch if its weak it will overheat
If your PT Cruiser is still overheating despite replacing components in the cooling system, check for possible issues like a blown head gasket, which can cause bubbles in the radiator. Additionally, ensure that the thermostat is functioning properly and that there are no air pockets trapped in the system. A faulty water pump or radiator obstruction might also be the culprit. It could be beneficial to perform a pressure test to identify any leaks or weaknesses in the cooling system.
If the radiator or reservoir cap is bad it could cause overheating because the system will not build up the proper pressure. Also the fan clutch could be worn out which would keep the fan from spinning fast enough to cool the radiator.
dose the electric fan run if not check the relay if it runs check the water pump
Check the timing.
have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
fan clutch?
check the heater core stopped up radiator
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
