Power steering pump fluid change, ‘09 XK...do it yourself?
#21
That is analogous to needing to run way more brake fluid through a system (using a power bleeder, and compared to the system capacity) to achieve a full replacement of the brake fluid. There is no way the power steering system capacity is 4l because the flush instructions tell you to run 4l through the system. It's probably 3-4x the capacity of the system.

According to ChatGPT...
what is the typical fluid capacity of a car power steering system
ChatGPT
The typical fluid capacity of a car's power steering system can vary depending on the make and model of the vehicle. However, in most passenger cars and light trucks, the power steering system typically holds between 1 and 1.5 quarts (approximately 0.95 to 1.4 liters) of power steering fluid. This is a general range, and some vehicles may have slightly larger or smaller capacities.
It's important to check your vehicle's owner's manual or consult with a qualified mechanic to determine the exact fluid capacity for your specific make and model. Overfilling or underfilling the power steering system can affect its performance and potentially cause damage, so it's essential to use the correct amount of fluid.

How much fluid do you estimate the pump, cooler matrix and hoses hold?
#24
Well, as stated, the total capacity seems to be of the order of 1 liter. The pump holds hardly anything. The cooler is not really a matrix, more like a straight piece of tubing. The biggest "reservoirs" are probably the fluid tank and the steering rack itself. I have no reason to suspect that the total capacity is off by that much.

Not a Jaguar at all, but here’s a similar back-and-forth about fluid capacity vs volume recommended for a flush:
