    • Replace the spring, retainer and nut over the filter and tighten down. The spring should still have some room to expand and contract but should be snug.

    • Fill the reservoir to the bottom of the metal rim around the top of the pump housing.

    • This car is getting power steering fluid, instead of automatic transmission fluid. Both are OK. The power steering fluid is clear.

    • Now, turn on the engine. Be sure the car is in park or neutral first. Turn the steering wheel left and right, as far as it will go, a few times to get out any air.

    • Top off the fluid as needed. Never let the pump run dry.

    • If your fluid is very dirty, simply repeat the process of sucking out fluid, putting the filter back in, filling the reservoir, and then running the engine and turning the wheel until it looks clean.

결론

Finish by re-installing the cap and taking it for a test drive.
