Coolant Question

469 Views 2 Replies 2 Participants Last post by  VW_Fam
I really need some help. I just purchased a 98 Jetta GL from original owner. Coolant is low and previous owner said Auto Zone sold her Zerex G40. I’m panicked because I have always ordered G12 for my VW’s. I’ve searched online and throughout forums and have read conflicting answers.

I would flush and use G12 but I’ve read it’s not a good idea to flush because after 25 years now it’s sure to stir up sediment that I’m afraid could just start a whole new list of problems.
Does anyone know if it safe to continue using Zerex G40 ?

G40 will be fine. (y)
Have added G40 to G12/G13 & vice versa with no problems for years.
Enjoy the Jetta & worry not. 😀.
