SEAL BULK 5P7666 - Caterpillar

At operating temperature, the engine cooling system is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap on the radiator is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
