Have you been experiencing issues with your Jeep Wrangler JK’s coolant temp sensor? In this video, we’ll walk you through the process of replacing it. The coolant temp sensor may not be an expensive part, but getting to it can be a challenge, especially in the JK model. Let’s dive in and see how it’s done.
To access the sensor, you’ll need to look under the steering shaft, at the back of the head. It’s a tight spot and reaching it can be tricky. One option is to remove the wheel and fender liner to reach the sensor. However, as an alternative, we’ll attempt to access it through the fender well to avoid removing the wheel.
Upon further inspection, we realized that the fender liner is riveted, making it difficult to access the sensor without removing it. As a result, we decided to change our approach and access the sensor from above, reaching our hand up in the tight spot, and carefully maneuvering a wrench to remove the old sensor.
The new sensor is then installed, and the fender liner is put back into place. If you don’t have a lift, taking off the wheel and fender liner is the recommended method for sensor replacement. Once the new sensor is in place, refill the coolant and ensure all air is purged from the system.
If you encounter a code for the temp sensor, clearing it using a scan tool and following a proper coolant bleeding procedure is essential. Once everything is completed, your Jeep Wrangler JK should be good to go. For a step-by-step visual guide, check out our video on coolant bleeding procedures for the JK model.
