I own an 11th generation thunderbirdequipped with an all-aluminum aj35 engine - same as jaguar. can i use this for its anti-corrosive benefits?

Thank you for your interest in our products and your question! Yes, we support the use of our Zerex G40 Phosphate and Nitrite Free Concentrate Antifreeze/Coolant 1 GA in your Ford Thunderbird. Due to the chemistry being slightly different than factory fill, we would recommend a complete drain or flush and refill to ensure no compatibility issues.

What color is this coolant?

Thank you for your question! Our Zerex G40 Phosphate and Nitrite Free Concentrate Antifreeze/Coolant 1 GA product is pink/violet in color. The product is suitable to mix with factory fill G-40 Antifreeze/Coolant for top-off or used in a drain and refill service.

Does this meet vw g13. spec ?

It meets the requirements for 2016 Porsche Carrera

Would this be compatible with 2003 vw golf gti?

Yes, it would as it meets all the specifications by Volkswagen's original required G12+recommendation ("ZEREX G-40 meets both the ASTM D3306, D4985, and D6210 specifications" - ECSTuning.com) and exceeds them.
