Product Description
One of the lesser-known parts on your BMW Z4 is the coolant
expansion tank. This part is responsible for catching and storing coolant overspill from the vehicle's radiator. Your BMW's coolant is designed to stop the car engine from overheating. It gets heated inside the radiator to its optimal working temperature. When this happens it expands and spills out. The expansion reservoir catches and stores it before it spills on the road.
How To Know If Your Expansion Tank Needs Replacing?
Some common symptoms for your BMW’s expansion tank failure include:
- The reservoir is constantly empty
- The engine over-heating
- Coolant leaking out of the tank
If you notice any of these signs on your
car it might be the expansion reservoir. Don't worry though as this
