Mixing Peck Sierra & Prestone LowTox Coolant


Recommended Posts

I’m needing to top off my coolant overflow tank on a 2015 Indmar 427SS LS3 motor. The only Propylene Glycol coolant available over the counter in my area is Prestone LowTox which has <.5% Sodium Nitrite. Can the 2 different brands be mixed and will the Sodium Nitrite harm aluminum block/engine parts?

thank you

When I added my heater last year, I was told mixing of the Sierra brand I used and the stock Malibu type was compatible.  Prestone was the other option I was given.
