As of this date AutoZone has it in their house brand. Part number A003.

NAPA has it in their house brand. Part number NAF1GAL. The NAPA near me also has the Zerex brand. Part number ZRX ZX001.

A local independent auto supply stocks it because they want to support the classic car market. It's labeled FVP Original Green Formula. Part number FVPGreen-Gal. It's distributed by FVPparts.com.

You want to only use the green coolant. They have it at Napa and it meets 1825M GM Spec.

For Zerex the first gallon is called Regular Green Coolant (GM 1825M), the second gallon is called Original Formula (GM 1825M). Zerex ZXRU1 is 50-50 and Zerex ZX001 is undiluted. The third gallon is NAPA coolant (GM 1825M).

OR

NAPA

Marc,
Thanks for updating us.
Besides the OEM head gasket in your experience have you seen any other area of the LT5 engine that is negatively effected by not using the recommended 1825M type antifreeze?

Marc Haibeck · 12-17-2017

I have not noticed any other particular corrosion problems Phil.

All,

Was just at Autozone. Part # 540722 now has code AZA003 on it. Green conventional. It looks to be the correct product.

Marc, can you confirm that the AZA003 is still the correct coolant?

Thanks

I could not find GM 1825M in Japan, not even on military bases since they only carry Prestone. I almost settled for Prestone, but after consulting with Marc, I kept searchIng the inter web. Fortunately, Advance Auto Parts could ship Carquest Conventional Green stuff to me and it’s on the way. [Thank you Marc! ATTACH]7016[/ATTACH]

I think that the AutoZone AZA003 is a good choice.

Buy premixed? Or 50/50 myself?

Premix is just easier. Makes no difference.
