Default GM Coolant # for C5s

I want to be sure the dealer replaced the coolant with the right product for the aluminum block and heads. What GM Part would the proper coolant be.
Thanks,
Mike

A 50/50 mixture of clean, drinkable water and use only GM Goodwrench® DEX-COOL® or Havoline® DEX-COOL® (silicate-free) coolant.


From the service manual.

This is what the dealer put in the car. I don't usually trust them knowing what product to use for a Vette so I would just like to double check with the forum.

10138 DEX KIT
12346290 coolant

There shouldn't be any problem with what goes in the Vette. GM puts the same coolant in all of its cars.
