You might have experienced this problem before – your car suddenly feels like it’s going to collapse beneath you as you try to steer. If you’re experiencing this issue, there’s a good chance that your power steering lines are impaired and need to be flushed. In this article, we’ll explain the process of flushing power steering lines and give you some tips on how to do it safely.
What is Power Steering?
Power steering is a system that helps a vehicle move in a desired direction by using the power of the engine to turn the wheels. Power steering works by sending a current through the power steering lines, which then turns the wheels. This current helps to guide the vehicle in the desired direction.
How to Flush Power Steering Lines
If you have a power steering problem, there’s a good chance that the fluid in the lines has become contaminated. Flushing the lines with clean fluid will eliminate the problem and restore power steering function.
To flush the power steering lines:
1. Park your car in a safe location.
2. Turn off the engine and remove the key from the ignition.
3. Open the hood and remove the air filter.
4. Remove the two spark plugs from the crankshaft pulley (near the engine).
5. Disconnect the battery cable at both ends.
6. Remove the power steering hose from both ends of the pump (the long tube with a metal fitting on each end).
7. Loosen all four bolts that hold on pump housing to vehicle frame (see photo).
8. Carefully pry pump housing away from vehicle frame and set it aside (photo 1, 2). Be sure to mark where it goes so you can re-attach it in reverse order when you’re finished (photo 3). Note: If your car has a power steering reservoir underhood, disconnect that first before proceeding – see instructions below for removal of reservoir
When to Flush Power Steering Lines
Power steering fluid ( PSF ) is formulated to resist foaming, but over time and with use, it can accumulate in the lines. Over time this can cause reduced steering response and even failure of the power steering system. A common indication that it’s time to flush the PSF is when you notice a decrease in overall steering performance as well as increased road noise.
1) Check the fluid level – The first step is always to check the fluid level. If it’s low, add fluid until it reaches the fill line on the pump.
2) Confirm system function – Once the fluid is at correct level, confirm system function with a test drive before proceeding.
3) Flush lines – Next, flush all power steering lines using a power steering flusher or pressure washer. Be sure to avoid contact with any moving parts or fluids in the engine bay.
Tips for Flushing Power Steering Lines
Power steering fluid is a valuable commodity, but like any other fluid in a car, it needs to be flushed regularly to keep it working properly. Here are four tips for flushing power steering lines:
1. Use a full-flowflush pump: A full-flow flush pump can move more fluid than a standard pump, so it can flush the lines more quickly and thoroughly.
2. Use the right fluid: Many power steering systems use lighter oil than typical fluids, so using the wrong type of fluid can damage the system. Check your car’s owner’s manual to find the right type of fluid for your vehicle.
3. Check the hoses: Make sure the hoses connecting the pump to the lines are tight and free from kinks or cracks. If they’re not, they can cause leakage and damage to the system.
4. Change the filter: Every 3,000 miles or every three years, depending on your vehicle’s mileage, swap out your power steering filter to avoid clogging and damage to the system.
