Been trying to find out how much fluid is in the 5.3 system … Scoured the factory service literature (inc. the “capacities” section) and cannot find it anywhere in there. So, if I were going to flush my system, how much fluid would I need to refill it - one bottle, two bottles, three?

Buy a bunch. The fluid is the same as the gearbox so you will need to top that up at some time?

You mean auto trans? Superblue has an automatic, not manual. I’ve heard that auto trans fluid can be used in a pinch for the PS, but never the other way around …
The FIRST Jaguar I know that used a different PAS fluid was the 2000 S-Type.
We were issued ESSO 998 and it had a FORD steering rack.
All the other Jaguar PAS systems use DEXRON of some sort. (the 1990-92 XJ sedans with SLS used the HSMO but you can use DEXRON when the SLS is deleted)
Jaguar parts dept issued Mobil Premium ATF for ALL OTHER PAS systems when I worked at the dealer.
