Coolant level

Both of those MSDS are for Prestone Dexcool. This may come as a shock, but the one with more water is the 50/50 pre-diluted version.

Good Grief!
It is great we have folks here that understand all that stuff but perhaps we could get a version that Penny (Big Bang) would understand.
Not all of us know which end of an Axon 700B is up.

okay, there's around 5% of an additive that dissolves metals, and keeps them soluble/in solution, so they don't gunk up your coolant system. :banana:

Just checked my coolant. It's been a few weeks since the dealer topped it off. Level is completely normal. I'm guessing the coolant was a little low from the factory or from sitting on the lot.

I just had my water pump replaced on my RS at 12,400 last Monday.
I need to top off my reservoir, slightly below the seam. Can I use the ACDelco coolant without adding water to top off or do they sell a 50/50.
I'm also guessing the Prestones DexCool 50/50 mix is no good?
