Hi. My car (Sport model) is overheating just after about 20 minutes of driving.
Lower hose and radiator are cold. Upper hose is very hot.
When I run car without radiator cap I can see no coolant flow.
After about 6 minutes of idling, coolant level is increasing and starts to overflow. With cap on, it takes longer and coolant overflow from reservoir.
Also heater is not working, always blows cold air.
Thanks in advance!
