The 3 pound valve for me never worked. I would still lose water. The engine heats up, the valve opens and out goes the water. It never kept anymore water in the system than there was without the 3 pound valve. I’ve found the best idea is to use an over flow tank. When your in traffic and the motor heats up the water goes to the overflow tank. When you rev the engine up the engine cools down and water returns to the radiator. Since I’ve installed the overflow tank I have not lost a drop.
