Jeep Engine Coolant Thermostats

As a jeeping enthusiast, you rely on your Jeep's engine to deliver an exceptional performance. Extreme driving, however, can cause average thermostats to overheat. When you are ready to upgrade your rig's stock thermostat, 4WD.com has you covered. Our complete selection of Jeep parts and accessories includes the engine cooling components and other parts you need to get the most out of your machine.

Cool Your Rig's Engine
When you are flying down the highway or crawling over rocks, your Jeep's engine works overtime. To operate normally, your rig must maintain an optimal temperature. Simply put, your old or stock Jeep engine coolant thermostat may not be up to the challenge. With a Mishimoto 180 degree racing thermostat or Superchargers thermostat, you never have to worry about keeping your rig's engine cool.

Power Your Jeep's Electric Fan
For your Jeep to dominate in traffic or on the trail, you need its cooling system to function perfectly. Of course, a high-powered coolant system relies on an electric fan. With frayed or old wires, your rig's fan may not run properly. Instead of risking your off-road adventure, upgrade to a high-performance electric fan wiring harness kit. The Be Cool harness kit is designed for easy installation on all vehicles.
