Customer Question

my 200 bonneville does not have a drain plug on my radiator, although I have flushed my radiators on other cars w/ plugs, I now find myself w/ a radiator that desperately needs flushing. I am not sure about how and where to disconnect the upper and lower hoses and the proper way to drain and flush the system using the hose disconnect method Any help or advice you could give me would be greatly appreciated Thank You for your time and knowledge Peace, Lisa Gehm

The radiator does have a drain plug. It is on the bottom of the drivers side radiator tank. There is a hole in the plastic panel below the radiator. You can insert a socket up through the hole to open the drain. The socket will either be an 18mm or 19mm size.

 

Arrow points to drain.

There is a hole about 1" in diameter that you can access the drain plug through. If you cannot find the hole in the panel, remove the panel. Each of the plastic clips in the panel will have to be removed to get the panel down. To remove the plastic clips, pull out on the center portion of each clip, then remove the outer portion.
