![]() ![]() Finally, a faulty radiator cap can cause your car to lose coolant rapidly, leading to an overheated engine and potentially damaging your car’s cooling system. Second, if the radiator cap does not allow coolant to siphon back into the engine, the engine will overheat and may suffer serious damage. First, if the pressure relief valve is not working properly, the coolant can boil over and cause an engine fire. If your radiator cap is faulty, it can cause a number of problems. When the engine is turned off, the radiator cap also allows coolant to siphon back into the engine, preventing it from overheating when it’s started again. The cap prevents the coolant from boiling over by allowing excess pressure to escape when it builds up. Faulty Radiator CapĪ radiator cap is a pressure-relief valve that sits on top of the radiator. Replacing your radiator cap is relatively easy and inexpensive, so it’s worth doing if it means avoiding a more serious issue down the road. If you notice that your coolant is boiling, or if you see bubbles in your radiator, it’s important to take action right away. This can lead to your engine overheating, which can be a serious problem. If your radiator cap is not functioning properly, it can cause your coolant to boil. If your radiator cap passes this test, then it’s likely not causing any problems with your car’s cooling system. Repeat these steps two more times to be sure that your results are accurate. If everything looks okay, turn off the engine and remove the radiator cap again. ![]() Check under the hood to see if there are any signs of coolant leaks. Start the engine and let it idle for a few minutes. Now, unscrew the vacuum pump and quickly put the radiator cap back on. Pump until you get a reading on the gauge of about 20 inches of mercury (this will take some effort). With the engine cold, screw the vacuum pump onto the radiator neck where the cap goes. To test the radiator cap, start by removing it from the radiator. All you need is a simple hand held vacuum pump. The radiator cap is responsible for maintaining the correct amount of pressure in the cooling system, and if it’s not working properly, it can cause all sorts of problems.įortunately, testing your radiator cap at home is relatively easy. If your car has been running hot, or overheating, you may have a problem with your radiator cap. ![]()
