What came stock, green or yellow coolant?

Yellow Coolant. The Green Coolant is a result of the TSB that suggested adding blue washer fluid to the cooling system in order to keep the system clean. :

Sorry, couldn't resist!

May sound like a dumb question, but do you still use the floating ball testers for the G-05 coolant ? Or do you have to use the big needle type .

I am interested in knowing, why are you not fond of GM vehicles? From my experience GM trucks seem to last forever with minimal repairs.
