Give them the vehicle information, and ask them what is now the recommended coolant for each.

Car manufacturers routinely issue what are known as Technical Service Bulletins (TSBs) to their service and parts departments. On my vehicles, which originally came with the orange coolant, Ford issued a TSB changing the coolant over to P-OAT. When I had to replace the water pump and hoses on my truck last year, I flushed the engine and put in the new P-OAT coolant. I'm going to make another post about these new coolants, and the importance of only using distilled water.
