kts - 2/24/2021 15:27 I'm not sure about a DCA4 additive, stuff I'm referring to said coolant conditioner on the bottle and was suppose to be added to the old style antifreeze in certain magnum engines.
The o-ring conditioner? Yes, it must be refreshed any time the coolant is serviced, or even if it just drained and refilled.
