Is this already obsolete since peak doesn't list this on their website anymore? I been adding new coolant to the system lately due to a leak in the water pump so I probably don't need it and I am ready to put it in to trash.
Will you be replacing your water pump soon?
You may have to search under the trucking industry(big rig) of coolants. You may find Final Charge there. IDK if it's obsolete but it seems as though I have seen FC recently. I wouldn't throw it away just yet.
