Power Steering Coolers

It’s common for us to get asked questions on how often car fluids need to be replaced. There are a number of different types of fluids in the vehicles on the road today. All vehicles have transmission fluid, wiper fluid, and brake fluid and engine coolant. Traditional internal combustion engines also have engine oil and gasoline, while the newer electric vehicles do not. Traditional hydraulic power steering vehicles have power steering fluid in addition to all of the other fluids but most electric steering systems don’t require any. Then, in addition to all of those fluids, there is also differential fluid and transfer case fluid, all depending on the style of driveline the vehicle has.

There are certainly some symptoms of a bad power steering system. Let’s discuss some signs that something in your power steering system is bad or that your system has developed a problem. Issues within the power steering system can at times be very obvious and at other times be very subtle. The power steering system is critical to the safety and drivability of the vehicle and should be inspected at regular maintenance intervals. In order to verify proper function of the power steering system, follow a couple of guidelines.

Are you filling up your power steering fluid reservoir and wondering, “Where is my power steering fluid going?” Maybe you know you have a power steering fluid leak but can’t find it. In either case, if you are filling the power steering fluid reservoir and eventually the fluid is going low again without changing out any components, you have a leak. The power steering system is a closed system and is not vented in any way. In order to find the leak, perform a few simple steps.

First, see if there are any leaks coming from the power steering hose. Some leaks will develop and be very obvious, like when the pressure hose leaks from the rubber and power steering fluid may be squirting out. Other times the leak may develop on the return side and since the pressure is much less, the fluid may leak at a slow drip. Other potential leak points are at hose clamps or where the rubber hose gets crimped to the steel tube. You will usually want to check for power steering leaks while the vehicle is running, as this allows the power steering pump to pressurize the system and some leaks will only be present when the system is under pressure. In addition to the hoses, the power steering cooler can also rust out and develop leaks. The power steering cooler is traditionally at the very front of the vehicle by the radiator and is often times very easy to replace. It should be inspected regularly for rust and damage.


Additionally, power steering hoses are also prone to deterioration. If your vehicle is more than seven years old, it might be time to start considering replacing your power steering lines. The reason for this is that power steering hoses will deteriorate from the inside out. The rubber will start to break down and pieces of it may end up in your power steering system. Often times replacing your power steering hoses and performing a power steering fluid flush can prolong the lifetime of your power steering pump and steering gear. Old power steering hose replacement is much less expensive and evasive to replace compared to the power steering hard parts.
