anybody running peak 50/50 long life coolent an is it necessary to use distiled water when mixing the coolent
Great info...If it says 50/50 on the bottle, then it is already premixed. You do not add water to it.
You only add water to "concentrated" engine coolant. In other words, not mixed.
As long as the Peak antifreeze is for aluminum radiators, you should be good. Just make sure you flush out the old antifreeze before adding it. If this is not possible to do, use a all makes, all models antifreeze. Prestone makes one.
