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 thermostat on this 2002 Chevy Suburban with the 5.3 liter V8 engine. It's the same part and similar process on these
Suburbans from 2000 and 2005. The items you'll need for this are a new thermostat from 1AAuto.com, flat blade screw driver, 10 millimeter socket and ratchet, drip pan, pliers, a pry bar, sandpaper, and coolant.

Start off by removing your coolant overflow bottle cap. By the driver side front wheel, go underneath in front of that, and at the bottom corner of your radiator, there is a thumb screw that goes to your radiator drain. Remove that and obviously have a drip pan underneath.

Now, loosen up this hose clamp, and this hose clamp using a flat blade screwdriver. Pull both ends of the intake hose out. Then lift it up and out. Now, using pliers, just push the two teeth together on this hose clamp. Then slide the clamp up the hose. Using a pry bar, just pry that hose free. You want to just pry back on it and pull on the hose at the same time. Now, remove this 10 millimeter bolt and the one on the bottom. We'll just fast forward as Don does that. Now, pull out on the thermostat, making sure you have a drip pan underneath. Then just pull the thermostat out the rest of the way. Use some fine sandpaper to make sure that you clean off any corrosion on the housing and then make sure that you clean up any debris really well.

On the right, is the old thermostat and housing. On the left, is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Take your new thermostat and feed it down into place. Then replace those two 10 millimeter bolts. We'll just fast forward as Don tightens those up. You'll want to tighten those to about 15 to 17 foot pounds. Now, push the hose back into place and then slide the hose clamp back up. If it clasped, unclasp it. If it didn't just use the pliers to slide it back up.

Then, take your intake hose, feed it back down into place and push both ends back to where they need to be. This hose needs to go underneath that radiator hose. Then, once they're both in place, just push this hose back up in. It will slip on to the side there. Then tighten up those two hose clamps with your flat blade screwdriver.

Now replace the coolant to the max fill line. Then you want to start the vehicle. Let it run for a little bit and heat up and let the coolant circle through. Then check where it's at and fill it back to the max fill line if necessary
