It is not uncommon for the radiator to develop a coolant leak. A leaking radiator will require replacement. When a leaking radiator is replaced the entire cooling system should be inspected and if any additional leaks are found they should be repaired also.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

    Had my radiator replaced and hoses Dec. 2012. Everything seemed fine up until a couple of weeks ago when my radiator yellow light came on and I checked the coolant and it needed coolant. Now I notice a leak, some runoff on the ground after it was sitting a few hours. Should I have the hoses checked again and replaced, or it this some other problem.

    I had this problem and had to have a cooling overhaul, see: engine overheating, water pump is a mandatory replacement if you don't want to fix it twice...
