Thanks for your comments. Much appreciated.
I think I found it. It looks like there is a cut out in the skid plate where the plugs are on the bottom of the engine. Do you remove the second plugs that has the wire mesh screen to clean out? If it's dirty what do you use to clean it out and remove any sediments. Making progress.
Now I need locate the drain plug on the radiator. I sure don't see one on the radiator. The service manual shows to drain the radiator you remove a plug that is not physically on the radiator.
