Do you see a leak or hear a whining noise coming from your car? Generally, this is not a good sign. If you hear this noise whether your car is idling or being driven, it may indicate a problem with the power steering. This could be a sign of either a leak or a restriction in fluid circulation. It’s important to diagnose the issue effectively, continue reading below for tips from our pros here at HCS Auto Repair to help jumpstart your auto repair with some DIY diagnostics.
First, it is critical for you to wear hand and eye protection at all times. There are five main components under the hood that need to be checked, and they are mostly visible. Since the system is a hydraulic power steering system, the first thing to inspect is the power steering fluid level. If it appears low, there is likely a leak somewhere.
Next, attention should be given to the power steering pump, which is responsible for circulating the power steering fluid. A whining noise while driving or steering often indicates that air has entered the power steering pump due to low fluid levels. If the pump is leaking, it usually occurs either from the pump seal behind the pulley or from one of the hose connections.
It is important to note that running low on power steering fluid can lead to significant damage to the power steering pump, ultimately costing more time and money in repairs.
It is easiest to view the power steering rack from underneath the vehicle. Given that any leak in the power steering system can result in steering difficulties, it’s crucial to inspect various areas of the power steering rack system. The first point of inspection is the shaft seal where the steering shaft connects at the top.
Additionally, it’s important to examine where each power steering line connects, as there are seals located behind each bellows boot. To inspect these areas thoroughly, the boot must be removed. There are also power steering transfer tubes that run across the power steering rack, which should be checked closely.
The fourth component to focus on is the power steering cooler, typically found at the front of the vehicle. Observing just inside the front bumper cover may reveal the cooler, which is generally positioned to allow for adequate airflow. Given its exposure to the elements, it may be prone to damage like rot. If the cooler becomes so deteriorated that it begins to leak, it could lead to significant issues.
Serpentine Belt and Tensioner
The serpentine belt and tensioner go hand in hand, located along the front of the engine. Upon closer inspection, it can be observed that the serpentine belt wraps around the power steering pump pulley. This pump is responsible for circulating power steering fluid through the system, so if the pulley isn’t spinning, fluid circulation will be compromised, leading to hard or glitchy steering, depending on how well the belt holds on.
It’s important to ensure that the belt is taut against the pulley and free from any tears, wear, or damage. The tensioner, commonly spring-loaded, should also be tested. Using a serpentine belt tool, one can check if the tensioner retracts as it should; if it doesn’t move at all when pulled, it may be exerting too much pressure on the power steering pump, potentially causing issues. On the other hand, insufficient pressure can also lead to hard steering problems.
A close examination of a belt can reveal damage that could otherwise be missed from a quick glance. A damaged belt reveals several cracks extending through the ribbed area. Such deterioration would definitely lead to issues with the power steering and could cause further problems with the engine.
If there is an internal issue with the tensioner, replacement will be necessary! For example, if the belt shows signs of wear, it’s advisable to order both the belt and tensioner together. Addressing any issues with the power steering system promptly is wise, as it is a safety concern and neglecting it could lead to more significant costs down the line.
When discussing the Power Steering Pressure Switch, it’s worth noting that if you have experienced a stalling condition while cornering, accompanied by the check engine light illuminating on the dashboard, you might be facing an issue with the power steering pressure switch.
To address this, you should disconnect the electrical connector, unscrew the switch from the pressure line, and then replace it with a new one before reconnecting it. After completing these steps, you should fill up the system and take the vehicle for a road test.
