Cooling System Flush

I would like to perform a proper flush.

I need a little help finding the engine block drain plug.
All I know is that it is on the passenger side.

I'd love to see a picture of where it is and know of any issues getting to it.

I have a 1998 3.4l, 4wd with an automatic.

Thanks

Thanks that helps a bunch

 

You're welcome FWIW - I opted to simply run 5 quarts of 50/50 mix through the system to flush. I'd fill the rad, run to op temp, drain, repeat. I figured that moved the coolant through the system to get the old/bad out good enough. Jiffy Lube should take the old coolant for free to dispose of - mine does.
