I'll go take a pict later, but I get mine from the chevy dealer. It's p/n 12378560.

It's expensive for sure, but it's what came in the car from BG back in 90.

I may go to the local NAPA store and see what they have on the shelf or what they can order that is an E-glycol silicate coolant 1825M spec. I have only one gallon of my GM stuff left after this yr's flush & refill.
