The engine on a Cadillac creates heat which, if left unchecked, can cause the engine to overheat and fail. To prevent this from happening the engine is connected to a radiator that circulates coolant through the engine and has fans mounted on the radiator to lower the temperature in the coolant and the engine. If the fan fails, the engine could overheat and fail. To fix this issue you need to replace the fans, which takes an hour or so to do.
