Hi, I'm Mike 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 1998 Honda Civic with the 1.6 liter four-cylinder engine. It's the same part and process on these Civics from 1992 to 1999. The items you'll need for this are a new coolant temperature sensor from 1AAuto.com, a flat blade screwdriver, pliers, 24 millimeter socket and ratchet, a drip pan, a funnel, and coolant.

To start off, you're going to want to drain your coolant. Right here is the drain plug. Put a drip pan underneath it and just twist that switch. You'll see the coolant start to trickle out. Now remove the radiator cap and that coolant will start pouring out quicker. Tighten up your drain.

Right here, on this clamp, you just want to push these two teeth together with a pair of pliers and just pull that clamp back. Now, you can just move the hose back and forth until it comes off. This harness, right here, plugs into your coolant temperature sensor. To disconnect it, you just need to push down the tab and pull it out. You can use a flat blade screwdriver or pliers to help you out with this. With a 24 millimeter socket, put it down over the spot that you just disconnected the harness from. That's actually your sensor. We just want to loosen it until it comes out.

In the back, is the old part. Up front, is the new one from 1A Auto. You can see they're identical and they're going to mount exactly the same. Twist your new coolant temperature sensor down into place and tighten it up with your 24 millimeter socket and reconnect. Use an emery cloth or something similar to just clean off where that hose connects. Plug in your harness onto the coolant temperature sensor and replace that hose. Using a pair of pliers, slide that clip back up into place.

Next, just replace your coolant. Now, replace your radiator cap and start your car for a while and then turn it off. Open up your reservoir bottle and then fill your reservoir about halfway up. Then drive your vehicle a little bit, just check the coolant often and fill it to the proper level. We hope this video helps you out.
