The Balance-Flow upgrade is designed to correct a fundimental flaw in the 6.5 engine's cooling system circulation. These engines suffer a relatively stagnant coolant flow in the rear portions of the cylinder block and heads. This poor flow causes excessive temperatures in the two rear-most cylinders (7 & 8) and imposses an undue thermal stress in the block casting, which contributes to early block failure. The cylinder heads, too suffer localized hot spots which leads to cracking and failure. The Balance-Flow system re-directs coolant to properly serve the cooling needs of the block and head castings, providing uniform coolant temperatures throughout the engine. This is a very important upgrade for any H-1 and should not be overlooked in the quest for performance and longevity. System is complete and ready to install with special fittings that attach to the rear of each cylinder head, as well as the flow-balancing tank, modified front coolant crossover manifold and high-temperature silicone hoses with permanent band type clamps. All components with the exception of the front crossover manifold are fabricated of high grade polished stainless steel. Designed for a lifetime of trouble free service - no shortcuts.
