If a car with power steering is towed, by
pulling it up on a flatbed truck, can that
cause a spill/overflow of the power steering
fluid if the engine is not on?
Doubtful. The fluid reservoir has a cap on it that seals it. When you have the cap on a bottle of Coke and you tilt it…does it spill??
I don’t see how. Cars are winched onto flatbeds every day, and they don’t lose power steering fluid.
Why don’t you tell us more?
