FAQ for Radiator Cap Repair

Q: What should be noticed when removing Radiator Cap?
A:
To avoid being burned, you should not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot.
