HOW DO I BLEED, OR PURGE AIR, FROM MY STEERING GEAR BOX SYSTEM?
1. After installing the gearbox, fill the system with fluid.
2. Raise the front wheels off the ground, do not start the vehicle.
3. Work the steering wheel back and forth, lock to lock, 15-20 times.
4. Leave the vehicle sit (overnight is best) at least 2 hours
5. Top the pump reservoir off again.
6. Work the steering wheel back and forth again 7-10 times
7. Have a person in the vehicle and another at the pump reservoir with a container of fluid & funnel ready to pour if necessary.
8. Instruct the person in the vehicle to start the engine. As soon as this happens, if the fluid level drops, be ready to pour in more fluid. The level must be kept at an almost full level or it will suck in air again.
9. If this procedure is followed properly, the air problem will be solved.

WHAT POWER STEERING FLUID SHOULD I USE?
RedHead highly recommends using the same fluid that the manufacturer of your
vehicle recommends. It is always best to use a name-brand fluid. Their
power steering gears are tested under pressure with Dexron 3 ATF before
they leave the factory. If you decide to change from what the manufacturer
recommends then Dexron 3, or comparable fluid, is an acceptable alternative.
ARE REDHEAD GEARBOXES SENT OUT IN CENTER POSITION?
Yes, they are sent out on center.

Great at first, 1 month out of warranty from date of purchase, and not when received, it now has a 2" play left and right. Should have went OEM but thought this was an upgraded version.
