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 2003 Chevy Monte Carlo with the 3.4 liter V6 engine, and the items you'll need for this, is a 19 millimeter deep socket and ratchet, and If you don't have one of those, it's going to be a slightly different procedure, and you're going to need a 10 and 13 millimeter socket and ratchet, a flat-blade screw driver, a pair of pliers, and a 19 millimeter wrench.
Your coolant temperature sensor is right down in here. You can actually get to it if you move this. You can reach your hand in. There is a tab on top, you can grab hold of with your finger and disconnect it. If you have a deep 19 millimeter socket, you can change it out without even having to remove the throttle-body, if you don't have that socket, we're going to show you real quick how to remove the throttle-body.
Now, just pull up on this hose and disconnect this harness, and then loosen up these two hose clamps. Pull this hose free from the engine, and then pull this hose free from your intake box, and just set that aside.
Next, remove those two ten millimeter bolts and this ten millimeter nut, right here. Now, pull this bracket down and set it aside, and then, pull out on this harness and pull it free. Do the same with this harness, and then push the tabs together on this hose clamp and slide it back. Do the same for the hose clamp on the other side. Now, just push that hose back, and then remove that 13 millimeter nut right there and then you want to remove that 13 millimeter bolt and this 13 millimeter stud bolt right here. We'll fast forward as Mike does that. Now, pull up this cable, and you want to just disconnect it from the top here, and then just lift the throttle body up and out. Lift up on the tab and disconnect the harness. Using your 19 millimeter wrench loosen up the sensor.
Once it gets to the point where you can pull it free, have the other one ready. Pull the old sensor free, and immediately push your new sensor into place and twist it in. We'll just fast forward as Mike tightens that up. Now, reconnect your harness. Take your throttle-body with the upper bolt in place and take this bracket and re-clip the wire to the top of the throttle-body, and then just run it down the track. Then, push the throttle-body back into place. Just tighten up this bolt. We will fast forward as Mike replaces the other bolts that hold the throttle-body into place, and tightens them up.
Now, push these hoses back on to this line, and just push the teeth together on the hose clamps and slide them back down into place. Then, we'll fast forward as Mike replaces the nut that holds that line into place and tightens it up. Now, take this bracket, and put it back into place, and replace the nut and two bolts that hold it into place. Re connect your harnesses, and then take your intake hose and push it back onto mass airflow sensor first, and then down onto the throttle-body. Then, just tighten up those hose clamps; you want to make sure the hose is all the way on before you do that. When you disconnected this line earlier, there's a good chance that it came free from back here, so just make sure that when you reconnect it up here that it's still connected back behind the engine there, and it just pushes right back into place. Now, reconnect this harness, and re-clip this to this bracket, and you're all set.
