I have a few questions about coolant that I am hoping the Pelican brain-trust can answer....

I have a 2004 VW R32, which has a 3.2-liter VR6 engine. This evening a warning message came on the computer that said the coolant was low. It probably isn't too low because the light went out after the engine warmed up. Still, I am sure I need to top-off the coolant.

According to the owner's manual, "The proportion of coolant additive must be at least 40% but not more than 60%...." It also says, "Never use any coolant additive other than our G 12 A8D additive...This coolant is available at VOLKSWAGEN dealers."

It goes on to explain the importance of the proper coolant in preventing corrosion, etc. "Under no circumstances may G 12 A8D be mixed with other coolant additives." It explains that the proper coolant is red, but if it is brown it means someone has mixed in another type of coolant, & it should be flushed out immediately. "Mixing coolant additives can result in serious malfunction or engine damage!"

I stopped at AutoZone on the way home & checked out their coolant products. Each brand advises that their coolant is universal & can be mixed with ANY color coolant.

My questions:

1- Can I add this so-called universal coolant without risk to my engine? Are you absolutely sure?

2- If not, do you think the required coolant is available at an Audi dealership (which is much closer to my home than a VW dealer)?

3- Does it matter that I am probably only going to add a small amount of coolant to top it off?

As always, thanks for your insightful answers.
