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 means 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 also 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.

Mishimoto Automotive (“Mishimoto”) warrants its products under this lifetime limited warranty policy (“Warranty Policy”). This Warranty Policy applies solely to: (i) Mishimoto Products purchased directly from Mishimoto or Mishimoto authorized dealers (each a “Mishimoto Product” and collectively, the “Mishimoto Products”) and (ii) the original purchaser of such Mishimoto Product (“Purchaser”). This Warranty Policy is non-transferable and all claims under this Warranty Policy must be accompanied by the original sales receipt. The terms and conditions of this Warranty Policy are subject to change by Mishimoto at any time without notice.

Note *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.

Clamp Q&A: 1. What type of clamp should I use for my application? a. Some clamps are best suited for specific applications, while others can be used for a wide range of purposes. When choosing a clamp, you should consider the type of part being clamped, the size of the part to be clamped, how much holding power is needed, and the cost of the clamps. 2. How do I know what clamp size I need? a. Our clamps are listed by either a clamping range or their nominal size. Clamps listed by nominal size are intended for use on that size hose or pipe. Clamps with a nominal size will match a product with the same nominal size. When clamping a hose or induction pipe, you may use a clamp with a clamping range. To determine which size clamp you need, assemble your parts as close to how they will be fitted in the vehicle. Then, measure the outer diameter (OD) of all pieces. If you cannot assemble the parts, you can measure the OD of the hose or pipe and add the thickness of any external couplers. For applications where the clamped hose or pipe slips over a barb, the OD is the only measurement you need to know. You should find a clamp whose clamping range covers this size. Ideally, you should choose a clamp where the size you need falls somewhere in the middle of the clamping range, as a clamp’s holding force is lower closer to its minimum or maximum diameter. 3. What is the difference between a worm gear clamp and t-bolt clamp? a. Worm gear clamps are for coolant hoses, low-pressure soft lines, catch cans, and stock induction piping. They are inexpensive, versatile, and available in a wide range of sizes. T-bolt clamps can be used for the same applications but are especially well suited for applications where higher clamping force is needed. This includes aftermarket forced induction couplers where higher boost pressures will be seen. 4. When do I need a constant tension worm gear/T-bolt clamp? a. Constant tension T-bolt and constant tension worm gear clamps are available for the same applications as their standard counterparts but have the added ability to provide constant clamping force over a wide range of temperature and pressure. The spring on constant tension clamps allow the part being held to expand and contract with temperature changes. Constant tension clamps are especially useful in heavily modified applications that generate a lot of heat or when standard clamps have failed. 5. What are the benefits of ear clamps and spring clamps? a. Ear clamps are best suited for vacuum hoses, catch can hoses, or other low-pressure applications where a permanent clamp is required. Manufacturers use this type when a part does not need regular service but needs to be very secure. Spring clamps are the easiest clamp to remove and install with a simple pair of pliers or your fingers. They are useful for vacuum hoses and low-pressure soft hoses that will be installed/removed often and where a large amount of clamping force is not needed.3. Where should the clamp be placed on my hose/pipe/coupler?a. For hoses that slip over a barb, the clamp should be placed behind the largest with some space between the edge of the clamp and the barb so that the hose is not cut by the barb. For clamps on couplers, you should place the clamp ¼” from the end of the coupler and behind the bead-roll of the pipe being clamped. If no bead roll is present, place the clamp ¼” from the end of the coupler.
