Nothing further needed in this post. I've located the tensioner, down low on the passenger side. I was assuming from my GM experience that the idler pulley under the P/S and A/C pumps on the driver's side was also the tensioner. It's not.
Jeez, I hate learning a new platform and brand.
It appears my clicking noise is the P/S pump. Time to order another and flush the cooling system while I await it's arrival. Thanks for the advice on flushing.
Onward through the fog.
