BMW 5-Series E39 (1996-2003) Radiators - Expansion Tanks and Parts
Coolant Expansion Tanks and Parts
If your cooling system has a problem the hot coolant will need a place to go and chill out! The coolant expansion tank provides a buffer for the coolant to 'overflow' too when the cooling system is running. Replace yours with a new one if it is cracked or if there is corrosion inside.
