Radiator drain plug/valve 2000 E430

I could not find the radiator drain plug of my 2000 E430, after removed the plastic cover under engine. Where is this radiator drain plug ? On the driver or passenger side ? Is there a picture of what the radiator drain plug look like ?
Thanks

Try looking at the lower right side of the radiator for the hose that connects to the coolant reservoir, then remove it.

I saw that small hose connects to radiator from reservoir, it can easily be removed, but I think releasing the radiator petcock would remove more old coolant from engine, and I am thinking using garden hose to force water into the engine through reservoir to flush out old coolant in the engine too.

Do anybody know where is the radiator petcock/plug is located ? what tool do I need to release that petcock ?

One one side of the bottom of the radiator there should be a plastic drain screw. There will also be a drain plug on the block.

I found that the 2000 E430 radiator drain plug is a red plastic plug from: http://www.importeccatalog.com

I don't remember to see this plug when I tried to locate it last weekend. I will try to locate this drain plug on my car radiator this weekend again to drain the old coolant.

Radiator drain location

The radiator drain is located on the bottom on the driver's side. You will need to remove both belly pans to access the drain. There will be a red plastic screw to turn to open the drain. There is a short nipple on the engine side of the radiator just above where the red screw is that you can attach a piece of hose to allow the coolant to drain into a pan without coolant going everywhere. The red screw doesn't have to come all the way out to allow it to drain., Hope this helps, Robert.

Yes, this is extremely helpfull. Thanks a lot Robert.

I did remove the black plastic under-stray under the engine, but did not remove the two "belly pans", that why I did not find the red plastic screw. I will concentrate on the bottom of the driver-side of the radiator, hopefully I will find the "belly pans" and remove them to gain access to the red plastic screw.
