Whether you’re crawling rock faces in Moab or crawling through traffic on the way to work, you need to make sure your 2012–2018 Jeep Wrangler JK’s engine is running clean and cool. The best way to do that is to install the Mishimoto 2012–2018 Wrangler JK Essentials Bundle.

This bundle includes everything you need to keep your JK’s engine running cool and clog-free. The centerpiece of this bundle is the Mishimoto Performance Aluminum Radiator. This radiator provides your Wrangler’s cooling system with an 18% increase in core volume and surface area, plus a 13% increase in coolant capacity. The increased size translates to more efficient cooling, while the extruded tubes with internal struts mean it can handle anything the trail or highway can throw at it. To make sure your coolant is flowing through the radiator when you want it to and doesn’t end up on the ground, this bundle also includes a Mishimoto low-temperature thermostat and a set of Mishimoto silicone radiator hoses. Our thermostat opens at 180°F (instead of the factory 203°F) to get coolant flowing to the radiator sooner, while the five layers of silicone and heat-resistant fibers in our radiator hoses keep the coolant on the right path.

To keep all of that coolant rushing through your new radiator and hoses clean, this bundle includes our Mishimoto coolant filter kit. The 3.6L Pentastar engine in the 2012–2018 Jeep Wrangler is notorious for clogging heater cores and radiators due to casting sand left in the engine from the factory. To prevent this casting sand from ruining your cooling system, you need to filter it out of the coolant. Our coolant filter kit includes a Wix® coolant filter that removes particles as small as 27 microns (about half the width of a human hair). This direct-fit kit mounts in line with your heater core in less than an hour and can help prevent damage from casting sand*.

Like all of our 2012–2018 Jeep Wrangler JK products, this essentials bundle is covered by our Mishimoto Lifetime Warranty for a lifetime of service.

*This coolant filter kit will not repair or reverse damage caused by sediment or other solids in the cooling system. Mishimoto recommends following all manufacturer cooling system service procedures and maintenance intervals.Mishimoto recommends changing the coolant filter after the first month, again after 3 months, and then every year after that depending on driving conditions. Because each engine was cast differently, there will be a different amount of debris in each engine.
