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 oil pressure switch in this 2002 GMC Sierra 2500 HD. It's pretty much the same procedure in most GM trucks from 1999 to 2002. And the only tools you'll need is an 8mm socket and a 1 1/16 deep socket and a ratchet with an extension, hopefully or preferably around 7 1/2 inches.

Okay. You want to start off by just removing the engine cover and to do that, you're just going to remove an 8mm bolt at the top of it. Okay. And that should just pull right up and you just want to set that aside. Okay. So we're going to show you from the front of the truck how to find the oil pressure switch. So you go straight back to the back of the engine and the screwdriver right there is pointing it out. Okay. So the first thing you want to do is you want to reach back down by the oil pressure switch and just disconnect the harness. Okay. So using that 1 1/16 inch deep socket you just want to put that down over the oil pressure switch and just loosen it. Now once it's loosened up, you just want to reach down there and twist it out and it should pull right out. You can see here the old oil pressure switch on the right and the new one from 1A Auto on the left. So you're just going to take that, put that right back down into it's spot and you just want to twist it in by hand at first, so it stays secure and then use that 1 1/16 inch deep socket to just tighten it back into place and we'll fast forward as he does this.

Next, you want to just reach down there and reconnect that harness to the oil pressure switch. Put the engine cover back into place and replace that 8mm bolt and when you start your vehicle, you should see the oil pressure come up on the pressure gauge there and that means that everything is all set.
