If you're running a high volume/pressure pump your system is generating much more heat then the stock system. Fluid overheating can cause damage to steering pump and steering box. Installing a oil cooler in front of the radiator is the best way to prevent this over heating. Our cooler features a fin area of 9" X 8" and does a great job of keeping the steering fluid temps under control in all conditions. Mounting kit is included with the oil cooler.
