Common Issues of a Toyota Camry Radiator Cap
A Toyota Camry radiator cap acts as a pressure valve for your car's radiator by sealing the engine coolant inside the tank. Since the radiator works as a heat exchanger for your car's engine, it needs assistance from the radiator cap, which then keeps the coolant in the radiator under a certain amount of pressure. The radiator cap, in short, plays a crucial role in the transfer of heat that come from the engine coolant into the air. So when your radiator cap becomes defective, it could cause a whole lot of trouble for you and your vehicle. Fortunately, you can avoid problems through proper troubleshooting. Here are some signs that your radiator cap is malfunctioning:
Your radiator cap gets to seal the engine coolant in the engine with the help of a lock. So when this lock starts acting up, it becomes extra difficult for your radiator cap to keep the engine coolant in the engine, given that it is also working against pressure. You have to make sure that the locks on your radiator cap are working properly. This way, you can be sure that the radiator cap won't easily get blown off from the engine.
Damaged pressure relief valve spring
The pressure relief valve spring works in coordination with the lock on your radiator cap. It compresses the lower seal, so you can easily close the radiator cap even if there is too much pressure in the cooling system. When you are having a hard time sealing your radiator cap, it could be caused by a defective pressure relief valve spring. And when this happens, it would be best if you can get a replacement immediately.
Your car's radiator cap is made with seal on its inner bottom part. These seal is supposed to keep the cap tightly closed so as to prevent the engine coolant from seeping through the gap and leaking out. One way to determine if the seal of your radiator cap is damaged is when the engine coolant or water is brought to a boil or when the substances flow out of the radiator.
