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 radiator overflow bottle in this 2002 GMC Sierra 2500 HD. It's pretty much the same procedure in most GM trucks, SUVs and pickups between the years of 1999 and 2006. The items that you'll need are a new radiator overflow bottle from 1A Auto; a flat blade screwdriver, pliers, vice grips, a funnel, a bottle or pan for the coolant and a 10 mm socket and ratchet.

To start off we're going to remove the air intake box. You just want to use a flat blade screwdriver to loosen up that bolt and that will loosen the clip and you can pull the air intake hose off. Then you just want to pull back on the air intake box and pull it up and out. You want to use pliers to pinch that clip together and then you want to pull that hose off. It helps if you loosen the cap. It releases some of the pressure and then the hose should pull right off. Next what you want to do is remove the 10mm bolt from the front of the overflow bottle and the 10mm nut from the back of the overflow bottle. We'll just fast forward while he does that.

Now you want to lift the bottle up and out and disconnect the connector there by pulling back on the tab. Now you want to tilt the overflow bottle back and clamp the hose with a pair of vice grips. Now you want to use a pair of pliers and push that clip together and slide the clip back off of the radiator bottle. Then you want to pry off that hose using a flat blade screwdriver. Once the hose is off you can remove your radiator overflow bottle from the engine. You want to dump the coolant into a bottle. Use a funnel or you could also use a pan and then you could pour it right into the catch pan. You need something to store the coolant in. You want it to be relatively clean because we are going to pour this back into the radiator overflow bottle.

You can see the old radiator overflow bottle on the right and the new one from 1A Auto on the left. They're exactly the same; same mounting brackets. You want to tuck your new radiator overflow bottle down into the engine. Reconnect that hose and you can disconnect your vice grip. Then you want to use a pair of pliers to slide that clip back onto the overflow bottle. Now you want to connect your clip and line up the overflow bottle. We'll fast forward here as he replaces the 10mm bolt and the 10mm nut that secure the overflow bottle.

Now you want to reconnect that top hose. Using pliers push the clip back together and it should release it. Now you want to pour the radiator coolant back into the overflow bottle. Replace the cap. Now you want to put your air intake box back in so just pull back that air intake hose. Put the back end of the air intake box in first and push it down into place. What you want to do is you want to line up the two clips on the bottom of the air intake box with the two holes in the body of the truck. Then you want to reconnect that air intake hose. Push the box down into those holes. Then using a flat blade screwdriver tighten up the screw on that clip and then you're all set.
