What happens if I mix power steering fluid with antifreeze?

I strongly recommend you have a complete flush of your cooling system. Any kind of oil that goes into your cooling system is detrimental to your rubber hoses and seals. Oil and rubber do not mix. It causes contamination and deterioration and weakening of the rubber hoses and seals. Do not run or drive your car until this is resolved.
