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.
The radiator or associated top hose sprays radiator fluid from the radiator aft leaving a fine white powdery spray pattern.
Thermostat opened permanently, setting off a Check Engine failure code upon inspection. Replaced cooling system, including radiator, WP, thermostat, belts, expansion tank, hoses, etc. due to mileage and desire NOT to come back in a few more miles to perform additional service that would require extra labor to remove radiator and fan assembly to get at failed components. I plan to keep this car for a couple more years, so had this work performed at my indie BMW shop.
Radiator leak just after new car warranty expired. Radiator and hoses replaced. Same problem again around 80,000 miles. Radiator had to be replaced again.
Had to get a new radiator. Not happy. Might sell the car.
radiator cracked at 100,000 miles
Radiator cracked, took it to Larry autoworks in Mountain View, CA. BIG MISTAKE! 500.00 later they want to charge me over a thousand dollars for doing a half A** job in the first place.
