Cooling system pressure should only be VERY (!) carefully released by giving the radiator cap a quarter-turn, but first cover the cap with a heavy cloth cloth or wear leather gloves since the coolant temperature will be over boiling. There is no separate pressure relief valve. Remember too to only add water to an overheated engine while the engine is running. Never add cold water to a hot engine without the engine running as doing so can crack the block.
