CAUTION: To help avoid the danger of being burned, do not remove the radiator cap or diesel surge tank cap while the engine and radiator are still hot. Scalding fluid and steam can be blown out under pressure if the cap is taken off too soon. Remove the radiator cap before draining the coolant, so the coolant is not forced out under pressure.
