Zerex G40 Phosphate and Nitrite Free Concentrate Antifreeze/Coolant 1 GA

Q: 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.

Q: 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.

Q: Does this meet vw g13. spec ?

It meets the requirements for 2016 Porsche Carrera

Q: 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.

Excellent coolant for Porsche

I could not find suitable coolant at the local auto parts shop or online, so I was very happy to find this coolant for my 911 turbo.

Good Stuff

Pretty cheap considering its concentrate. It’s the right stuff for VAG cars. not sure about mercedes or bmw. This one doesn’t degrade with heat from EGR systems or have other weaknesses OE fluids have.

Perfect for my VW Beetle

This product works with my 2013 VW Beetle. However - don’t forget to dilute the product with water (read your car specs for water to coolant ratio).
