Cooling system flush




Filled power steering fluid, overfilled.
Used turkey-baster type tool (designed for battery acid) and extracted some power steering fluid.
Was also low on coolant so I filled that.
Realized I may have overfilled coolant also (don't see any lines on the reservoir).
Used the same fluid extractor to remove some coolant.
Not realizing that would contaminate the coolant.
Now I'm concerned I need to do a full coolant flush.
Could be as little las a few drops of contamination, could be as much as half a teaspoon (I hope not)
Drove the car home (1.5 miles) instead of trying to extract all contamination.
Is this the full procedure?




Thank you!!
Ok. I might drain and refill the radiator for good measure and leave the heater block and engine block as they are.
Was reading up about this and everybody seems to think that the oil-based power steering fluid will break down the gaskets in the cooling system.




Coolant, I have no idea. It's a darker shade of blue but you can still see the blue. I'm not sure what previous maintenance was and was not done by the previous owner (s)
Part of the reason I'm totally down to do a drain and refill, or even a flush if it's not a pain in the butt to drain the heater core and engine block.
Do it. Just make sure to use the correct coolant and put the right amount in the right hole.
It'll be worth the peace of mind if nothing else.




I just don't want to cause seals, gaskets, etc. To fail in the long-term.

If I just hear a few of you old heads say that it's totally fine I'll feel okay about it.

Safe to drive for a week?
Drain engine block and heater core too or just radiator?
