So I came home from work last night and my grandpa tells me that he
accidently put about half a cup of coolant into the power sterring tank on
my grandma's Chyrsler LHS. Anyone know what kind of damage this will do,
if any?

 

dont run the car, drain it, and refill it.

The car shouldnt have any damage

 

Yeah... I'm not an expert, but my first instinct would be to drain and replace the fluid. Good thing he recognized the mistake at least.

 

I once put oil in my girlfriends coolant tank way back in high school before I knew anything about cars, lol.
