Why a 19-row oil cooler as opposed to the 25 or 16 row?
• The cooler size needs to be adequate to allow good cooling even in extreme climates, but no more. Any excess capacity is unnecessary weight and expense. The design of the HKS-700e makes it one of the easiest engines to cool, that you might ever encounter. The range of available sizes is an attempt to cover most possibilities. In tractor configuration, the 16 row cooler (235 mm length) placed in direct prop blast provides more than enough cooling in nearly every circumstance. The same cooler may also work well on tractor applications if mounted slightly out of prop blast. Often, the overall dimensions of some installations may dictate an oil cooler location where air flow may be more questionable. In such case, a 19 row or larger might make up for that shortcoming. Remember, it is easy to block air to get temps up. FYI, One manufacture now supplies the 16 row x 115 length cooler for their tractor mount HKS. In pushers, the 19 and 25 row are most common.
