Mine too had a leakage. I was coming back from KL when i stopped by Hilton to take a piss. When i came back on, realised the temperature needle touched H. Immediately stop the car at petrol kiosk, cool it down and pour water into the radiator, which was almost empty. Later on realised there was a crack at the top cover of the radiator. Like everyone here said, i just sent to the shop and he replaced a new top cover thats all. Cost me about RM300 to replace the top cover, with welding and workmanship and of coz plus a bottle of coolant.
