Paradox By Design Cooling System Upgrade Kit Humvee HMMWV 6.5 TURBO Diesel

Description: Paradox By Design HMMWV 6.5 TURBO COOLING SYSTEM 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 Humvee's with GM and GEP Detroit Diesel V8 6.5 TURBO 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. In the earlier 6.2 engines these higher 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, and increased piston to cylinder wall gap in the rear, among other improvements to reduce the catastrophic failures, but never addressed the cooling imbalance and the loss or performance from this. Paradox By Design developed our system using proven technology from our Motorsports background. The Motorsports industry have long known of the benefits to balancing the temperatures across V8 engines especially when running at the cutting edge of detonation needed to make maximum power. While that may not be the goal of most Humvee owners, cooler running temperatures, better power and efficiency are. Further the reduced heat from the rear of the engine is a welcome reprieve from hot cabin temperatures too. On average the hydraulic fan cycles on 25%-50% less than stock with our kit installed. This is the most obvious advantage to our kit as this greatly reduced the loss of power, added noise and fuel burn! The Paradox system opens up the blocked off rear coolant area of these engines and allows for flow to the front of the coolant circuit. By opening this up we create coolant flow to the once dead area of the block. The added benefit is reduced air/steam pockets and constant coolant bleeding to the overflow tank. Countless hours of testing and tuning went into developing this kit with the proper flow for maximum benefit as well as to assure proper match to the front of the block. Diesel engines need to operate in a narrow band of temperature to maintain optimum efficiency. Without our kit the front of the block is over-cooled and the rear under-cooled leading to loss of power and efficiency. Our system is hand assembled in the USA with all USA made parts. We use Aerospace certified AN fittings, high temperature/pressure stainless steel hose with a soft outer layer to not cut into your soft metal parts. We fabricate a custom bolt on replacement for the rear coolant block off plates which are produced on a CNC Machine from solid Billet aluminum, which includes new gaskets as well. Everything is a true bolt-on system. Should you desire to remove the system it is fully reversible as well. All systems come with a color step by step guide for installation. Buy with confidence with a full one year warranty against manufacturer defects and workmanship. Compatibility: This kit is for ALL Military HMMWV 'Humvee' 6.5 TURBO trucks (this will not fit 6.2 and non-turbo trucks, please find our other listings for these). NOTE: Though these engines are very similar to the 6.2, 6.5, and 6.5T engines used in civilian applications or military CUCV trucks, they are not 100% compatible. Please see our other listings for cooling systems for your specific application. Add Ons: We can option your cooling kit with a few add ons if you desire. We can add the ability to flow coolant to an aftermarket water cooled turbocharger with our kit. Another option is to add a port for you to add an aftermarket coolant temperature gauge. Yet another option is to add an aftermarket fuel pre-heater system for cold climates or bio-diesel applications. These are all add ons we can option into our cooling upgrade kits now or in the future. >>>>THE EBAY COMPATIBILITY LIST IS NOT CORRECT, THESE FIT ALL HMMWV HUMVEE TRUCKS WITH 6.5 TURBO ENGINE. These kits may be shipped worldwide however EBAY tags these as for USA use only. Please contact us directly for shipping outside the USA. We are now on version 3 of the kits, all fittings are now black and the plates are now a solid one piece billet. The overall fitment and function is the same. Inventory is selling out fast and supply is limited. Photos may be of similar kits but are substantially similar<<< What our customers have to say: "The package arrived today and it was well packed and the quality was evident right away. This is no cheaply made kit from overseas and obvious care was taken to make it. The instructions were easy to follow and I had the kit installed in less than an hour! Wow is all I can say! I never expected such a quick change to make so much difference in my Humvee! All of a sudden I have a great truck to drive. The power is much higher and the fan hardly comes on at all anymore. The idle is smoother and it puts out much less smoke. The heat inside the truck is definitely lower too. Good job Paradox!" "I was very skeptical, and reading the online discussions I just could just not figure out how this worked. I figured what the heck, if it doesn't work I will send it back or cancel my charges with my card company. Well best thing I have done to my truck yet! Not only does it work as advertised but actually does far more! I cant say enough about the overall improvement in the way my truck drives now." "My M998 has been a hot runner from day one. I have replaced nearly every part in the system, sometimes more than once with no effect. Well PBD upgrade system was the magic bullet! The fan used to kick on all the time and stay on just killing the power, now it hardly comes on at all. I will be buying whatever they do next!" "I had to wait a full month for the kit as one of the first to buy it and it was worth the wait! I did some other things while in there but all in all the install was super easy and less than 2 hours. Strangely the truck warms up faster now? Once warmed up it stays constantly at 200 now where before it would spike to 240. The fan runs like 1/2 the time as before and the power is way better. It is still early to tell but my last tank lasted another 30 miles further than normal so looks like that has improved too. My 4X4 group of friends will be buying too once they are back in stock! "I was thinking snake oil, akin to the tornado or magnets for the fuel. Well not here, this is the real deal. Spoke with Derrek before buying as I did not want to waste my time and money, he convinced me. The box was small but the contents were high end and well made. Instructions clear and install easy. M998 is happy with it and now my M1038 is getting one too!
