kjølevæskereservoar

A kjølevæskereservoar, also known as an expansion tank or coolant reservoir, is a vital component of a vehicle's cooling system. Its primary function is to store excess coolant and compensate for the expansion and contraction of the coolant as it heats up and cools down. When the engine runs, the coolant heats up, increasing its volume. The reservoir provides a space for this expanded coolant, preventing excessive pressure buildup within the cooling system. Conversely, as the engine cools, the coolant contracts, and the reservoir replenishes the system, ensuring it remains full and preventing air from entering.

The reservoir is typically made of translucent plastic, allowing for easy visual inspection of the coolant level. It is connected to the radiator or other parts of the cooling system via hoses. Many reservoirs also feature markings indicating the minimum and maximum coolant levels, which are crucial for maintaining optimal engine temperature and preventing overheating. Regularly checking and maintaining the correct coolant level in the reservoir is essential for the longevity and efficient operation of the engine. Low coolant levels can lead to inadequate cooling, potentially causing severe engine damage.
