So i just fixed my oil leaks and i thought that was the cause of the smoking coming from under the hood but now i found out that power steering problems can cause smoking as well. If my power steering is leaking out would the pump be the first logical thing to change. Since i got the car it has always been hard to keep fluid in the car. Do know if this helps anyone but when the car is running and the fluid gets low the fluid bubbles in the power steering bottle and alot of times im guessing the pressure pops the cap off its always laying behind the bottle. What you guys think i should do ??
