After having my radiator replaced the hack that worked on my car severed the high pressure hose for the power steering. One week after the radiator my car became difficult to steer and within minutes it was nearly impossible to steer. High pressure hose replaced to the tune of $250.
About every 60k both power steering hoses replaced total just over $600.
