OMIX 17218.11 Coolant Temperature Sensor for 14-18 Jeep Wrangler JK and 14-21 Grand Cherokee WK

I received the correct part quickly, however, the part was missing the necessary crush washer needed for the install. I would not install this part without the crush washer. Something to note as well is that when you order the part it is sold as OMIX. Mine showed up in Rugged Ridge packaging. No worries though as they are one in the same. Lastly, this coolant sensor (17218.11) is often confused with 17218.10 which is an oil temp sensor and installed up under your intakes directly into the oil cooler/filter whereas the coolant sensor is installed on the engine block, driver side rear, close to the firewall. Easily accessible through the fender well after removal. Hope that helps.
