Hey there. The two coolant chemical compositions are different and may cause corrosive action or gelling of the mixture. If it becomes corrosive, it may damage gaskets and metal components in the engine. If the mixture becomes gelled, then it may clog the engine, radiator, thermostat, and heater core passages. The coolant should be drained as soon as possible and flushed out with water a couple times then put in fresh 50/50 mixture of correct coolant. A certified technician from YourMechanic can assist with a coolant flush and perform any other adjustments at your home or office if needed.
