The coolant tank gives the fluid an additional place to go after expansion and contraction from system temperature changes. Since it’s exposed to these drastic temperature changes, cracks and wear can occur. This replacement unit will replace that damaged tank to restore your cooling system. Be sure to pick up some coolant to refill your system. The reservoir includes the coolant level sensor internally, and is not available separately.
