No, it is not recommended to use a car's coolant expansion tank without a pressure relief valve. The pressure relief valve is an important safety feature that helps regulate the pressure in the cooling system and prevents it from becoming over pressurized. Without a pressure relief valve, there is a risk of the cooling system building up too much pressure, which can lead to leaks, damage to the system, or even potential safety hazards. It is important to ensure that the coolant expansion tank is equipped with a properly functioning pressure relief valve for the safe operation of the vehicle's cooling system. **
