Many car owners do not pay attention to the condition of the power steering fluid. As a result, the steering wheel becomes heavy and annoying noises appear. To prevent this, you need to understand the symptoms, causes, and how to fix it.
What is Power Steering and its Functions?
Power steering helps the driver turn the steering wheel more lightly, especially when the car is traveling slowly or stopped. The system works with hydraulic fluid or an electric motor, depending on the type of car.
The main function:
- Reduced power when turning the steering wheel
- Makes steering more responsive
- Improve comfort and safety
When the fluid is low or dirty, the steering wheel immediately feels heavy and produces a humming sound. This condition can also damage steering components if you leave it too long. Therefore, maintain power steering fluid regularly
Causes of Heavy Steering and Buzzing Sounds
If the steering wheel feels heavy and there is a buzzing sound, there are a number of factors that are usually to blame. Here, we will discuss the three main causes related to power steering fluid:
1. Reduced Power Steering Fluid
Fluid is usually reduced due to leaks in hoses, pumps or connections.
Symptoms:
- Steering wheel feels heavy when the car stops
- There is a buzzing or screeching sound when turning the steering wheel
- Liquid level in the reservoir drops
When you find these symptoms, check the source of the leak immediately to prevent further damage.
2. Dirty or Curdled Power Steering Fluid
Fluid that has not been changed for a long time can become contaminated and thicken, requiring the pump to work harder.
Symptoms of dirty fluid:
- Cloudy or dark color.
- Burning odor when hot.
- The steering response falters.
In this case, fluid replacement is the best solution. Autogard Power Steering Fluid is highly recommended as its anti-oxidation and anti-foam formula keeps the pump durable and the steering smooth.
3. Power Steering Pump Problems
If the buzzing sound does not disappear even after the fluid has been changed, the pump may be starting to wear. This condition is often triggered by dirty or insufficient fluid. If left unchecked, the cost of repairs can be much more expensive.
Solutions and how to overcome them
Luckily, the problem of heavy steering and buzzing due to power steering fluid can usually be solved with simple steps. Here's the complete guide:
