E39 coolant leak driver side

 · Hello, We just purchased a Cab with 50K on it. Just noticed a small puddle of the blue coolant under the front of the car closer to the drivers side if the car. Does not appear to be leaking so much that the coolant reservoir is too low and does not seem to be directly under the radiator.  · On my '02 , the slow leak was coming from the driver's side of the radiator.

BMWs have multiple components in their cooling systems and any of them could cause a leak, however the most common of coolant leaks are caused by a failed Coolant Temp Sensor located (in most cases) in the lower radiator hose. Checking the sensor for a leak is simple, just open your hood and look down at your lower radiator hose, find the sensor and you can see coolant remnants originating from the sides of the sensor and you should see a pool of coolant under the hose onto your lower engine. Most BMWs are known for their brittle cooling system components. From plastic water pumps to plastic radiators and hoses, you never know what is going to lea.
