Auxiliary coolers can be bought at almost any auto parts store across America and are almost certainly never a bad thing to add to your vehicle. Auxiliary coolers can be used to cool steering systems, engine oil, tranny fluid, or even differential fluid if you want to get really high-tech and run a pump to your axlehousing. We cannot think of one instance where you wouldn't benefit from an auxiliary cooler (unless you place it in a position where it could get whacked by something).
