Out of Pentofrost - Autozone Peak coolant silicate-free or including silicates ok?

[neilpaku]

I "accidentally" ran out of Pentofost SF and need a top-up. Autozone have something called Peak coolant for "European" cars including Audi. They have two versions - one without silicates for <2005 and they have one with silicates they claim for model year 2005 and up. All their words - are either of these ok for my 2005.5 B6? I want some insurance before heading over to Canada tomorrow so would pick one jug up if I knew it was ok to use. I have to flush the system in spring when I replace the radiator so it'll get refilled with Pentosin at that point.

I've already watered it down more than I want with distilled water, and I'm about to park it outside in Niagara overnight where temps are in the low 20s. Of course, I completely forgot that I can just swing by VW and pick some up from there. Thanks anyway folks.

In Canada? Good way to crack a block. It’s called antifreeze for a reason.

Picked up G13 from Audi on the way back, they don't supply G12. Need a new radiator in spring so I'll swap over to G13 then.... I'll do that when I send it in for a derust and respray. Have to ensure the radio is working in the C4 A6 before that happens or the wife will be serving dinner on the front door step.
