Mazda Demio (DE3FS)
Sometimes when I accelerate, I hear a slight sound. It sounds 'kkrrrrrr'. Also sometimes i feel a minor vibration When the car is stopped in the traffic... (N, D, S - all gears gives the same vibration)
I suspect that it it a problem in the radiator? I checked the coolant level, it is perfect.
Any idea what may be causing this?
Thanks.
