FORD 7.3L / 6.0L POWER STROKE RADIATOR RECOVERY TANK CAP
Your radiator cap controls the pressure inside your cooling system. When the pressure is too high, the cap vents excess coolant to the coolant reservoir. If your cap isn't venting, this causes excess pressure in the cooling system, and can cause leaks or a collapsed radiator hose. A cap that is no longer sealing could also cause a leak. At operating temperature, coolant can evaporate from the open system. Any time there is a coolant leak, there is a possibility of the engine overheating.
