Re: Coolant Recommedation
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?

Coolant Recommedation
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]

Re: Coolant Recommedation
I think that the AutoZone AZA003 is a good choice.

Re: Coolant Recommedation

Re: Coolant Recommedation
Hi guys,

Re: Coolant Recommedation
Is this peak antifreeze the correct kind for a 90 ZR1. Trying to support the local hardware store but don't want to get the wrong type
