On average, the cost for a Ram ProMaster City Pressure Test Radiator Cap is $95 with $0 for parts and $95 for labor. Prices may vary depending on your location.
In a pressurized cooling system like those found on all cars, your car’s radiator cap is calibrated to seal in coolant to a particular pressure point, then allow some vapor to escape once that threshold has been reached. The ejected fluid is piped into the overflow bottle you might have seen in the engine bay. Then, as the engine cools, the coolant level may drop inside radiator. When that happens, a reverse-flow valve in the radiator cap opens to allow fluid from the bottle to return to the radiator. A radiator cap that isn’t working properly may cause too much fluid to escape the system.
If your car’s engine overheats, or the overflow bottle seems overly full, have the radiator (and radiator cap) pressure tested.
Not having this safety valve on the car’s cooling system operate properly can over- or under-pressurize the system, leading to damage to hoses, the radiator, and even the car’s cylinder head.
