What are the 2 types of power steering pumps?
Power steering pumps are essential components in modern vehicles, making steering easier and more responsive. As a seasoned auto repair expert at Kevin's Autos, I’ve worked on countless power steering systems and understand the importance of knowing the different types of power steering pumps. In this article, we’ll explore the two main types of power steering pumps and their unique characteristics.
1. Hydraulic Power Steering Pumps
Hydraulic power steering pumps are the traditional type of power steering system found in many vehicles. These pumps use hydraulic fluid to assist in steering, making it easier for the driver to turn the wheel. Here’s how they work:
- The pump is driven by the engine via a belt and pulley system.
- It pressurizes hydraulic fluid, which is then sent to the steering gear.
- The pressurized fluid helps reduce the effort needed to turn the steering wheel.
Hydraulic power steering pumps are reliable and have been used for decades. However, they can be less efficient compared to newer systems, as they rely on the engine's power to operate, which can slightly reduce fuel efficiency.
2. Electric Power Steering Pumps
Electric power steering pumps are a more modern alternative to hydraulic systems. These pumps use an electric motor to provide steering assistance, eliminating the need for hydraulic fluid. Here’s what makes them unique:
- They are powered by the vehicle’s electrical system, reducing the load on the engine.
- Electric pumps are more energy-efficient, as they only operate when steering assistance is needed.
- They allow for more precise control and can be easily integrated with advanced driver-assistance systems (ADAS).
Electric power steering pumps are becoming increasingly popular in newer vehicles due to their efficiency and compatibility with modern automotive technologies.
Which Type Is Right for Your Vehicle?
The choice between hydraulic and electric power steering pumps often depends on the make and model of your vehicle, as well as your driving preferences. Hydraulic systems are robust and time-tested, while electric systems offer improved efficiency and advanced features. If you’re unsure which type your vehicle uses or need assistance with maintenance or repairs, feel free to contact Kevin's Autos for expert advice and service.
Frequently Asked Questions
What are the 2 correct steering methods?
There are two correct methods of steering a vehicle, which are known as the pull-push method or the hand-over-hand method.
What are the disadvantages of hydraulic power steering?
The cons of hydraulic power steering
- Mismatch power assist: When the car is driven slowly, the belt doesn't move fast and therefore the assistance is reduced.
- Prone to leaking: As the system requires fluid, it can cause leakages and can block if particulates get into the system.
Which is better, EPS or hydraulic power steering?
This is primarily because an EPS system is generally simpler and easier to maintain than its hydraulic counterpart. Electric systems do not require power steering fluid to work and only draw power when needed, making them more fuel efficient than hydraulic systems.
What are the 2 main types of power steering pumps?
Power steering systems are either hydraulic (HPS) or electric (EPS), though nearly every vehicle manufacturer is turning to or has already turned to electric power steering. In hydraulic systems, a pump pressurizes fluid to help turn the wheels, while an electric system uses an electric motor to assist.
Can you convert hydraulic power steering to electric power steering?
EPS kits work on vehicles with or without original hydraulic power steering. Many aftermarket companies offer electric power steering assist conversion kits. They cover a wide range of vehicles, including classics and hot rods. By swapping out the hydraulic steering pieces, the engine bay is cleaner.
What are the two 2 most common types of steering systems?
We all know how important steering function is to driver and passenger safety. There are two basic types of power steering systems: rack and pinion and conventional.
How much pressure does a GM type 2 power steering pump have?
Pumps are rated at 1200 PSI rating, 850 PSI valve available upon request.
What is the most common type of power steering pump used?
Vane pumps
Vane pumps are the most common type of power steering pump used in the vehicle which features a rotor in an oval or elliptical housing. It also comprises vanes on the rotor which pushes against the housing.
What is a GM type 2 power steering pump?
This is the smaller GM type II pump fitted with a March Performance serpentine pulley kit. The pump has a much smaller appearance than that of other pumps, plus it works great with rack-and-pinion. 02. The Gen II pump can produce pressure that can exceed some rack-and-pinion's pressure ratings.
How do I know if my power steering is electric or hydraulic?
Open the owner's manual and find the vehicle specifications or technical parameters section. Generally, the type of power steering system will be listed here. If the manual specifically mentions "hydraulic power steering system" or "electronic power steering system", then you can determine the vehicle's equipment.
