Tonight, when checking my ps fluid, I accidentally broke the coolant line that runs to the airbox thermostat. The ps reservoir was unfortunately open at the time, and I'm not sure how much spilled. I took a sample with a syringe and there are definitely bubbles of coolant/water mix in the fluid. I'm sure the bubbles have settled into the system.... On a brighter note, the fluid looked pretty clean and red, just a little dark.

As fate would have it, I was planning on flushing the system tomorrow, following these DIY threads:

My question is: how many times should I cycle the system (turning steering wheel and refilling) during the bleed process to make sure all of the coolant mixture is flushed from the system?

Any tips here? Feeling like a complete dumbass :( , but hoping a simple flush will take care of the contamination.

Thanks guys, looking forward to any help here.

PS I rerouted the long coolant hose back into the throttle body, away from the intake sensor, and removed the smaller hose with the broken plastic fitting. Is this an ok temporary solution?
