Description

Want improved cooling for your Jeep EcoDiesel engine?  It is easy with the BulletProof Supplemental Cooling System.

By adding an additional external radiator, this cooling system increases the cooling capacity to minimize 'defuel' conditions while towing. A cooler engine means more power and added engine durability.

The diesel powered Jeep has become quite popular and has a ton of really good attributes.  The addition of the diesel engine in the Jeep platform gave the rig great horsepower and amazing torque for towing or low speed high engine load conditions.  The problem exists in the fact that the manufacturer chose to not change the overall "look" of the Wrangler/Gladiator to accommodate the EcoDiesel option.  Of course, if it is a Jeep, it must look like a Jeep.  That created some serious design constraints for the cooling system effectiveness.  Our own experience with the 2021 EcoDiesel equipped Gladiator tells us the radiator was grossly undersized and cooling system performance was, well, lacking, especially in Arizona!

As you can imagine, reconfiguring the cooling stack - or even redesigning the front of the Jeep for that matter - is a monumental task, so an alternative was developed.  Simply stated, this product will tap into the engine cooling system - specifically the coolant circuit to and from the engine oil cooler - and then route this coolant out of the oil cooler to a remote mounted supplemental radiator.  This radiator is then safely mounted between the frame rails and between the front skid plate/bumper assembly.  This solution is the best way to add cooling system capacity without having to completely redesign the truck.

Engine Temp and Power Game Changer!

We use our gladiator to tow a 24 ft boat in the Florida summer and have been battling coolant temp and defueling issues until installing this kit. The bracketry and instructions were spot on, making this kit a breeze to install.

Can tow in the summer

I live in Phoenix AZ. Purchased a used 2021 Gladiator Rubicon late August 2023. Tow an overland pop-up trailer (MDC Robson), about 5,000 lbs. Only significant changes are 37” tires and installed aux cooler from Bulletproof Diesel. Towed trailer from Phoenix up the I-17 to Camp Verde then to Rim Road trail (Mogollon Rim). Elevation at start approximately 1,100 ft to 7,800 ft total. Left Sunday morning at 06:00 to beat the Phoenix heat, temp was about 86 degrees at start, about 78 degrees at trail on the Rim. I maintained 55 mph most of the way to Camp Verde. From Camp Verde to the summit was the real test and was able to maintain at least 45 mph with a max oil temp of 247 degrees. Route back was from Payson to Phoenix Wednesday evening. Temperature during toughest pull was 92 degrees at 21:00, slowed down to 45 mph, max oil temp 255 degrees. I am pleased with these results as my Gladiator is a “jack of all trades” and fits the needs and fun for our family.

Vast Improvement

Great solution for adding additional cooling capacity. Not a complete fix, but a significant improvement especially for towing.
