How to Prepare for Changing the Power Steering Fluid?

The first step to changing the power steering fluid is to check for your vehicle’s most suitable power steering fluid. This information should be easily available from the vehicle’s manual.

Once you are ready with the type of fluid and purchase the same, you need to get rid of the old fluid to put in the new one. That requires you to locate the reservoir in your vehicle’s engine area.

First, you should get the jack to lift the car. While doing so, make sure that the front wheels are off the ground. Now, the real deal of how to change power steering fluid begins.

Drain the Old Power Steering Fluid

Lifting the front of the vehicle off the ground makes it easier to go below the car. Put the jack under the vehicle before you slide underneath it. Wear your gloves and grab a can to hold the drained-out old fluid.

A turkey baster helps to get the old steering fluid out of the reservoir. If you find that a bit of fluid remaining in the reservoir, turn the car on to ignition mode and power it till the radio and lights come on without starting the engine.

That should allow you to turn the steering wheel and flush out the left-out fluid, which you will be able to hold below the car.

Fill the Reservoir with New Fluid

For starters, place a funnel on top of the reservoir to pour the power steering fluid precisely and at proper levels. Once you have successfully filled the reservoir, close it with the cap back on.

Turn the ignition on again and move the steering wheel sharply to the left and the right. Go back to check the steering fluid levels, and add more if required.

Ensure the Fluid Levels Again

Finally, remove the jack and let the front tires touch the ground again. Now, start the car and keep the ignition on for about 20 seconds. Turn the power steering wheel from left to right and then from right to left to check the fluid level.

You can go for a short drive around the block to check if the steering wheel is running well without any noises.
