How do I change anti-freeze on 98 Olds Bravada

I want to change the anti-freeze on my 98 Olds Bravada but cannot find the cockpit valve. Where is it? thanks, Kevin O.

Some cars no longer have one, on some it is under the radiator or on one lower side of the radiator. On the cars with no petcock, the only way to drain the system is to pull a hose. But there are kits you can install so the next time there is a way to flush the system. Not sure about your car.

yes yours has a valve to drain the antifreeze can't remember what side it is on and it is not the normal looking one it should take a 1/4 inch ratchet with an extension to open it the extension fits into the hole on the plug
