Professional Test Each radiator will pass professional test before delivery to ensure no leakage. Maintenance Regularly clean your radiator to prevent clogging that may lower cooling efficiency. Don't mix different brands of coolant. Important notes: 1. The radiator cap fails to release the pressure reaching the maximum value if the cap does not pass the product test. 2. Continuously increasing radiator pressure may result from a damaged thermostat that is unable to circulate in a large area. 3. The high temperature of the water tank may be because the radiator fan does not work. 4. Expel the air from the cooling system by referring to a user manual or repair manual. 5. Please add coolant refer to a user manual. 6. Please wait until the stream subsides before opening the hood, because hot engine compartments may result in serious injuries. 7. Please stop your vehicle once “ENGINE OVERHEAT/ HIGH TEMPERATURE” shows on the dashboard or if there is steam coming out from under the hood. 8. Please keep your hands or clothing away from the fans and belts. Otherwise, clothing (tie, scarf, etc.). 9. Do not loosen the radiator cap until the engine and radiator are cooled down.
