When you remove the pump or tank and servo, they are disconnected from the hoses, the hydraulic system must be filled in regular ATF.
ORDER EXECUTION
1. Start the engine and leave it idle function.
2. Turn the steering wheel very slowly four times from one side to another, until it stops and this time carefully refilled the ATF in the tank until such time as the bubbles do not stop appearing in the air.
3. The liquid must not drop so low that the air is reached in the system.
4. Remove oxygen prior to the time that the concentration level of ATF in the tank will not be stable and did not stop to go to the air bubbles.
5. Turn the engine and test the ATF.
6. Make a run-in and check the steering endurance over long distances.
Enjoy the ride!
