Brought to you by 1AAuto.com, your source for quality replacement parts, and the best service on the Internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20+ years' experience restoring and repairing cars and trucks like this, to show you the correct way to install parts from 1AAuto.com. The right parts, installed correctly; that's going to save you time and money. Thank you, and enjoy the video.

In this video, we'll be replacing a radiator bottle on this '99 Pontiac Grand Am; same as any '99 to '06 Grand Am. The tools you'll need are pliers, a flat blade screwdriver, and a 10 mm socket, ratchet and extension. A coolant recovery tank. At 1A Auto, we sell nice, new replacements. These are under pressures, so sometimes they can rupture and crack, and that's why you can leak fluid. Maybe somebody worked on your car and cracked one of these hoses or something, and broke the hose. If so, we sell a nice quality replacement. It has the sleeves in here for extra strength. It comes with a cap and everything. This one's fine on this car, so I'm just going to show you how to get it out. I'm not going to totally take it out, because it's still got coolant in it, and I don't want it to drain it out. It's pretty easy.

There are three hoses you've got to disconnect. You just use pliers, and pull those clamps off. Then you want to twist the hoses; that's how you get them started. Then you twist as you pull off. That disconnects it. You want to do that one, that one, and then this one. Right down here is an electrical connection; that's your low coolant sensor. Just unplug that. Then, just one 10 mm bolt; I use my air ratchet here. Then, basically there's another clip here. You just kind of need to work a screwdriver in there and pry it away from the fender a little bit, and then it comes up and out. Putting it in is the reverse. You clip it down in there, connect all your hoses. Put your 10 mm bolt back in. Plug in the harness. Let's tighten up this bolt. Take your pliers, and squeeze the clamp; work it back on here. If you want to, you can put a little bit of soapy water or something to help you. That's about it; three clamps, a harness, and a 10 mm bolt. Unclip this right there, and you're good. This hose back here can actually stay with it.

We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll free, 888-844-3393. We're the company that's here for you on the Internet, and in person.
