You may be asking yourself, “is it okay to bypass a power steering cooler?” Let’s hear what our experts have to say. If your vehicle comes equipped with a power steering cooler, it should not be bypassed. There are reasons why the OE car company added this important part to your vehicle.  The cooler is designed to prevent the power steering fluid from overheating and damaging power steering components. Not all vehicles are equipped with a power steering cooler. So, if your vehicle has one, it is because the engineers designing the vehicle deemed it was a necessary component for the operation of the vehicle.  Unless you want to risk a $1,000+ repair of your steering system, the power steering cooler should never be by passed.

How necessary is a power steering cooler? Well, if the vehicle came equipped with one from the manufacturer, they deemed it was necessary in order to maintain proper power steering fluid temperature. Power steering fluid has an operating temperature that is required to be maintained in order for power steering systems to operate as designed. If the fluid exceeds the intended operating temperature pre-mature failure and inconsistent power steering assist.

If a vehicle comes equipped from the manufacturer with a power steering cooler it is a necessary component. The cooler helps lower the temperature of the power steering fluid after it leaves the power steering gear box, or rack and pinion unit. The friction generated in the steering unit can generate enough heat to cause the steering fluid to rise above its operating temperature. This causes the fluid to become less viscous and diminish its ability to properly lubricate and cool the system. Power steering fluid that is above operating temperature can cause excess steering effort than the driver is used to, and become potentially dangerous. In addition to the fluid becoming too hot, the result can be the power steering pump and steering mechanism becoming overheated resulting in premature failure. Not all vehicles come from the manufacturer with a power steering cooler installed. The reason for this, is that during vehicle design testing it was determined a power steering cooler was not necessary. Only vehicles that run the risk of developing overheating power steering fluid come with a power steering fluid cooler from the manufacturer.
