When my car idles, the water temp goes over max. The oil temp is normal before the middle mark. The only thing with my car is the radiator fins are 75% bent. Can this cause the water temp to skyrocket in a matter of 10 seconds? Even with the water temp going to max, there's no engine warning lights or warnings from the car's display. The car is supercharged but I don't think there is any relations to the water temp. So any thoughts or anyone else encountering this?
