Jeep JK Wrangler Cooling Parts

Make Sure It Fits Your Vehicle

The cooling system of your Jeep JK Wrangler or Jeep JK CRD has to endure a lot with all your heavy-duty off-roading. Make sure it is in tip-top shape by replacing all fluids regularly and swapping out malfunctioning parts. Do this with high-quality parts from 4WD.com. Our Jeep Wrangler cooling system diagram helps you locate the parts you need to keep your Jeep running cool and efficient.

Premium Replacement Parts
Your Jeep's cooling system consists of many different parts, small and large. No matter if you're looking for radiator caps, coolant pressure caps, radiator hoses, belts, pulleys or air conditioning condensers, we have you covered. We also sell JK Wrangler radiators from Crown Automotive and Omix-ADA, two of the brands that you love most. Our Jeep auxiliary Toc cooler or transmission oil cooler from Crown Automotive helps keep your gear oil cool. It's easy to install and a worthy investment if you don't already have one. Trust 4WD.com with all your cooling needs.

Take Good Care of Your Manual Transmission
Even though you don't need to change your Jeep's manual transmission fluid as often as your motor oil, don't neglect this highly important fluid. Your Jeep Wrangler JK manual transmission fluid ensures that your transmission doesn't overheat and fail.

A manual transmission on the trails can be challenging but it is also a lot of fun. Coming up on a boulder, knowing that you have to find the right shift, throttle and clutch work is a rewarding experience. You are fortunate to have a manual stick-shift transmission, so take good care of it.

100% Price Match Guarantee
Don't waste valuable trail-time on trying to find the best price on Jeep parts. With our 100% price match guarantee, you can request a price match up to 90 days after your purchase. Keep that manual transmission running cool with quality cooling parts from 4WD.com so you can hit the trails with confidence and enjoy your off-road rig for many years to come.
