Military CUCV Hybrid (HMMWV Crossover) Cooling System Upgrade kit
PARADOX Military CUCV Hybrid 6.2lts COOLING UPGRADE KIT (patent pending)This is simply the best bang for the buck upgrade you can make to your truck, period! Must do before any performance or horsepower mods.All CUCV trucks with GM Detroit Diesel V8 6.2 engines all share an inherent design flaw in their cooling circuit. Due to the packaging of the cooling system, coolant distribution is disproportionately fed to the front of the engine block and heads. The rearmost cylinders run significantly hotter due to this inadequacy, while the fronts are overcooled. Diesel engines run best in a tight band of temperature. In the earlier 6.2 engines these higher rear temperatures led to many of the well known failures in those engines which are nearly always in the rear two cylinders. Later blocks increased block density and used better metallurgy, among other improvements, to reduce the catastrophic failures, but never addressed the cooling imbalance and the loss or performance from this.
