MINI Power Steering Pump

A problem with your steering wheel is always concerning, and definitely something you’ll want to get fixed right away. Unfortunately, in the case of your Mini’s power steering pump, these issues are not terribly rare, as it is a relatively common issue in this model. Here’s a quick guide to everything you need to know about identifying and fixing your Mini’s power steering pump failure.

What is a Power Steering Pump?

Mini Coopers are designed to be both compact and fun, so the bulkier steering systems that are found in most cars aren’t ideal for Minis. That’s why your Mini is equipped with something called an Electro-Hydraulic Power Assisted Steering system. It’s unique because it combines the horsepower of a big car with the compact ease of driving a small one. Unfortunately, however, these systems come with a unique set of issues that can get scary if they appear and are allowed to go on unchecked.

What Causes Power Steering Pump Failure?

The most common cause of power steering pump failure is heat buildup. This is a major mechanical issue with Minis — enough so that you may already be familiar with the power steering pump’s bad reputation for premature failure. Sadly, this reputation is pretty well deserved because the pump is located directly below the exhaust manifold. This means it’s incredibly close to the road, so it’s very vulnerable to damage from rocks, bumps, and other ordinary hazards of driving. Small rocks can even get caught in the auxiliary fan, slowing or clogging the fan completely. As you might imagine, this can lead to excessive heat build-up, which in turn can cause your pump to fail.

In that case, it is important to keep an eye out for any problems, so what should you expect with power steering pump failure? Well, the good news is that your steering won’t completely lock up or become unresponsive. That may be a small comfort in the face of looming car repairs, but it is a great benefit when it comes to the safety of you and your passengers.

Although the steering wheel won’t lock up completely, it will become very heavy and difficult to turn, as the failure means it’s now unable to access any power steering assistance. Your steering will now be completely manual, which means you’ll be directing the tires on your own, with no help from the hydraulic steering pump.

How to Identify Power Steering Pump Failure

Unlike some vehicular issues which can often go undiscovered, you’ll probably notice a power steering pump failure right away. No need to waste time on complicated diagnostic guides; you’ll know as soon as the wheel feels suspiciously heavy and you feel like you’re having trouble controlling the car. Because the power steering can cut off at any time, this can lead to some frightening experiences for drivers. Obviously, this isn’t an ideal driving situation, so you’ll want to get your power steering pump failure corrected immediately.

It is worth noting that the effects of a failed steering pump will be more obvious at lower speeds, as the wheels are easier to turn manually when the car is going faster.

How to Fix Power Steering Pump Failure

In the event of power steering pump failure, you’re almost guaranteed to need a replacement pump assembly. Depending on the root cause of the failure, you may also need to replace the auxiliary fan or risk another imminent pump failure.
