Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the coolant temperature sensor on this 2006 Jeep Liberty with the 3.7 liter V6 engine. The items you'll need for this are a new coolant temperature sensor from 1AAuto.com, a 16 millimeter wrench, a drip pan, a flat blade screwdriver, a funnel with a screen, a 3/4 inch socket and ratchet with an extension, and an 8 millimeter Allen bit.
Remove the cap to your coolant reservoir. Your drain plug's located right here under the bumper. You're using a 16 millimeter wrench. Just loosen that up. Make sure you have a drip pan underneath to collect the coolant.
To access the coolant temperature sensor, you're going to have to disconnect a couple harnesses. Pry up the red clip on this harness, and then push in the tab and pull the harness free. Now, right here, push on the tab on this harness and pull this harness free, and this is actually your coolant temperature sensor. Use a 3/4 inch socket and just remove the sensor.
On the left, is the old coolant temperature sensor. On the right, is the new one from 1A Auto. You can see they're identical and they'll mount exactly the same. Put the sensor into the socket and lower it down into place. Just twist it in. Then use the ratchet to tighten it up. Now, reconnect the two harnesses, and on that white harness, make sure you push down that red clip.
Use your 16 millimeter wrench to tighten up the coolant drain plug. Refill your coolant reservoir using the proper type of coolant. Some of this may go down into the engine, as well, so it might take a little while to fill. Replace your cap. You're going to want to bleed the air out of the coolant system, so there's a little bleeder plug here. Loosen that up. You'll want to check the fluids. Make sure you keep the fluid tank at the appropriate level. Then, as you can see here, loosen that up, and you'll see air come out. You don't want to take it all the way out, just have it loose. It lets the air come out. Then, once you fill your coolant bottle to the right level, tighten that plug up. You should hear that your engine's getting the coolant through here. The temperature gauge will settle in, right where it should be.
