The power steering system is a very important part of the car. It helps in the steering of the car smooth and effortless. It uses hydraulic pressure to steer the car.

One of the most common mistakes made by many people is to reverse the lines of the power steering system. I also made this mistake in the past, and I had to face dire consequences and severe damage.

When I looked it up on the internet, I needed assistance finding specific information about reversing power steering lines, as it is very important.

To provide you with a complete guide about what happens when you reverse the power steering lines, I am writing this article.

Quick Answer:

If you are in a hurry, read this !!!

Power steering lines carry fluid from the power steering pump to the steering gear. Reversing the lines causes the loss of power steering assistance and fluid leakage, which can lead to fatal accidents. So. Don’t put yourself and others at risk, and fix this problem as soon as possible!!

What Are Power Steering Lines?

Power steering lines carry fluid between the power steering pump and steering gear. The high-pressure line carries fluid from the pump to the steering gear, while the low-pressure line returns fluid to the pump.
If these lines are accidentally reversed, the power steering system will not function properly or will fail.

The Main Issues Arose From Reversed Power Steering Lines:

The main issues due to reversed power steering lines are mentioned here.

Loss of Power Steering Assistant:

The power steering system relies on hydraulic pressure to assist the driver in turning the wheels. If power steering lines are reversed, the fluid will not be transmitted correctly from the power steering pump to the steering gear.

This causes the loss of the power steering assist and makes it difficult for the driver to turn the wheels, especially at low speeds and when parking.

Damage to the Power Steering Pump:

Reversing the steering lines causes the flow of power steering fluid in reverse order. It causes the power steering pump to work in reverse and causes damage to the pump. This can also result in premature failure of components of the pump.

Fluid Contamination:

Reversing the steering power lines wear and tear the internal components, mainly the seals and hoses of the pump and steering rack. The broken parts of these components cause contamination in the fluid.

The leak of Steering Fluid:

Due to the damage to internal components, leakage of fluid may occur and your steering pump becomes dry. When the added or drained fluid is improper, it cannot maintain the steering control, and unwanted situations may occur.
