PaulC,

It's me again; I'm still having trouble finding the drain plug onmy Expy. It doesn't seem to be where you said it should be. I see some sort of plug on the lower right side of the radiator. What I mean by lower right side is: It's not on the bottom of the radiator & it's not on the back of the radiator. It's on the passenger side of the vehicle & on the side of the radiator.

The "plug" I see is an off-white, sort of yellow-ish colored plastic hex head screw of some type. The hex head is approx. 1/2"-5/8" tall. Am I looking at the right thing?

Thanks in advance
