Hi and thanks for using 2CarPros. Com.

I believe it is on the lower left side of the radiator (passenger side) Some were on the opposite side. However, take a look at picture 1. It shows how the drain is situated regardless of side.

I do not know if you are replacing the radiator, so I thought I would add the directions for removal and replacement in case you need them. All remaining pictures correlate with these directions.
