Meziere Expansion Tanks

Meziere expansion tanks have two main functions. They can be used as a fill point when the top of your radiator is lower than the engines water outlet, or to deal with the expanding volume of water when a recovery system is not utilized. The bottom of the tank is plumbed to the low pressure side of the cooling system, the smaller fitting on the upper portion of the tank is plumbed to the high points on the engine and radiator to remove trapped air and aerated water. The expansion tanks can be located high and out of the main flow of water, which allows air to be purged from the system, making the entire cooling system more efficient. Show Less
