I would have the cooling system flushed and coolant replaced. DEF is very caustic.
Then you need to "accidentally" remove it ... pronto, which may mean flushing out the entire coolant system if the engine has been run.
Have the coolant changed immediately and you will be ok.
You drain the oil immediately. If you run the engine with coolant mixed with the oil you will do serious harm to the engine. If you continue to drive it in this condition you will destroy the engine.
What happens when you put windshield washer in the coolant in a Grand prix Pontiac
drain all coolant then flush. refill with anti-freeze
Yes. By little I'm talking two tablespoons. If more, then purge and refill with coolant and water.
you run the risk of major bearing fatlure.
After coolant is added run vehicle to normal operating temperature and re-check coolant level
go and hve the power steering system flushed
Nothing happens, except your wallet will be lighter.
Nothing, just don't make a habit of it.
Drain the coolant reserve chamber and refill with new coolant. Can use a turkey baster ot remove hose from chamber.
