My 2003 Protege5 heated up i fea days ago. I Saw a small crack in the radiator and changed for a new one. I put everything back together and made sure all the hoses were tight enough and they were, but the car is still heating up. I will like a respond asap because i need to head to work. If anybody know whats the problem feel free to call 321 746 1431 thank you.
