I've recently encountered a problim in my Baleno 2005. My car runs normally with or without A/C. The temperature remains normal (i.e. at mid level). But when i get stuck in traffic jams, the temperature starts to rise. And it remains around Quarter higher than mid level until my car is stuck. As soon as i get out of traffic n' reaches certain speed level, say in 3rd gear the temperature comes back to normal and remains so for as long as i drive.
I've checked teh readiotor, the coolant level is fine. The coolant is new as well, only two weeks old. Can anyone help please??
