Product Description
The TOPRAN Coolant expansion tank (103 006) is an original-equipment-quality replacement reservoir manufactured by TOPRAN. Positioned directly within the engine bay, its primary function is to store overflow coolant as it expands due to high operating temperatures and pressures, safely returning it to the cooling circuit as the engine cools down. It helps maintain the necessary hydraulic balance and system pressures required to prevent air locks and engine overheating.
