SLS removal

Postby Lightweight » Sun Jun 28, 2020 12:02 am

For everyone who has had the SLS removed did they drill the cap to the fluid reservoir?
Should the hoses have been capped off or looped back on themselves to keep fluid going through the pump?
Thanks

I personally don't have any experience of / with this system, other than to suggest from an "engineering" point, of view the pump needs to be further employed in order to keep the power steering operative :?: ;)

Currently assuming the pump has two impellers, one for PAS and the other for the SLS system. However my assumption is that if the SLS side runs dry it will eventually cause the entire unit to seize.
More investigation is in order. I am sure I read a TB from Jaguar about the removal of the SLS system so I need to find that again.

Update - So I have not been able to find the retrofit guide yet, but it does look like there are various generations of SLS with the later cars 93.25 onwards having separate pumps in the same housing.
