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.

Solid product for you vehicle coolant needs

Online purchase is more cost effective than getting it at the parts store. Additionally, not all locations have this available without ordering it. I bought this for its value and convenience of Amazon delivery. Were I live (Nashville area), it is a very fast delivery. It is good to have some coolant around if doing minor adjustments or maintenance where you loose some coolant and need to top up. Or if you are doing major work requiring a full refill, get the required amount ahead of your work. Ironically, it is the coolant supplied at the dealer (but costs more needless to say). I personally like the concentrate to mix up what I need and ratio mix. I've used this product for a number of years with no difference in vehicle cooling performance from OEM.
