Why is my brand new radiator leaking?

The potential causes of a car radiator leak could be counted on one hand. The leading and most common cause is corrosion in the radiator. Radiators, hoses, and hose connections collect sediment and rust that over time can punch holes in the radiator. In a few instances, weak coolant can be the cause of overheating.
Where is the upper radiator hose located?
The upper radiator hose runs from the radiator to the motor . You can usually see most of this hose. The lower radiator hose is harder to find. To locate it, get underneath the car and look for a smaller diameter hose leading from the radiator into the heat wall of the car.
What sealant to use on radiator hose connections?
You can choose to use a high-heat silicone sealant to gum up the hole through which your radiator leaks. Silicone sealant is excellent, because it will expand to fit the hole and harden, and will withstand a great deal of heat.
