You will benefit from the Jaguar Power Hydraulic System manual. For many years this manual was pretty unknown to owners and was a main reason for why many gave up on the rear suspension height regulation since they had no clue how it operated. The manual gives you distinctions in the rear suspension height control design which was the basic reason for the complicated hydraulic system. Many cars have been converted to regular shocks but you may still understand the hydraulics and how the design evolved from 1988 up to 1994. lilldata.se/jaguar/XJ40-SLS.pdf
Wrecking yards bro you gotta watch the wrecking yards. The Row52 app for your phone is pretty cool. Old Jags have a lot of metal $$$ for the junk yards here in the US they squish them Pretty fast. So you gotta get em when they list them and harvest parts. I still have a box full of electrical harvested parts for my sons jag in the basement just in case.
Hey man! I live in Newcastle, WA. And am finishing a engine transplant in my 88 xj6 but am having trouble finding the mineral oil applicator. Where did you find yours?
This mineral oil system you describe has nothing to do with the braking system. It is suspension and power steering. The advice on using the right fluid is spot-on, but the systems are separate. The hydraulic brakes use DOT 4.
Dot for breakfast in the master cylinder reservoir. Green hydraulic fluid on the right side of the car . Don't get these 2 confused because you will be in big trouble the system system in the 1988 jaguar uses breakfas this brake fluid on the left and hydraulic mineral oil on the right very very important
FYI anyone that needs the mineral oil?? just go to any typical drug store and buy the generic mineral oil that they sell, Walgreens, etc, possibly walmart, not sure. the generic mineral oil is cheap and works just as well as the Castrol product that Jaguar recommends (it may actually be the exact product that is in the Castrol bottle? not sure). you will still need the applicator as seen but you can get around that if you are astute enough to figure it out. anyway, i have a 1989 xj6 and have been using the generic mineral oil whenever i need; have been using this for over 10 years with NO problems at all. Actually an old Jaguar mechanic told me about this substitute years ago. Good Luck. Happy motoring.
MARK Me Fascinating. Not sure I would agree just based on the temperature heat exchange. Over-the-counter mineral oil It’s not engineered for high heat compression situations. It may work but it also may be gumming up your system. Pre 1990 The pump for the mineral oil is actually inside the engine itself. There is no pump to replace if it goes bad. I see this as a risk and reward choice. The mineral oil I put in the Jag is not that expensive when you buy it from a auto parts store.
My '90 does not; after '89 they went from vacuum boost to electric ATE/Teves system- it's very different, no green reservoir. My rear self-leveling system is removed with coils & KYB's all around. '90 was a big change-over year where they went from the digital dash to analog, the electrical system is re-vamped with a lot more German and Japanese parts (hell, even the AF meter- which says "Lucas" on it- has 'made in Japan, Hitachi marked on the body) than UK pieces by far
olikat8 - These XJs NEVER had vacuum boosters. That's what the mineral oil did - operate the boost system (as well as the self-leveling suspension). And yes, they also used standard brake fluid up top in the white reservoir.
i know this is an old video, but i just bought a 88 XJ6 and cannot find this fluid any where, been to every place in my town and they all just tell me its just brake fluid lol. so if you have a link or something you would be my HSMO Hero lmao Thanks!
@@RussShawTV Ya i seen that, I snapped a picture, I'll try again on the weekend. Just hope i can find the nozzle lol. Thanks for the reply. Loving the car so far. Found out its a true Sovereign from Coventry England, Was wondering why i had the round headlights yet yours are square?. Was it an option?
Can you check with your old English teacher and learn how to say "SPELLED" ? Yes, this comment was 3 years ago, but even way back then "SPELT" is not a word. How histerical that you are correcting the dude for spelling "BRAKE" wrong, and YOU use the word "SPELT"? - Just to keep the progression intact, I will add my two SENSE.
That hydraulic pump is mounted directly to the OUTSIDE of the front timing cover by three small bolts. VERY easy to get to...
Why would he say you have to replace the engine if it goes bad than??
STUPAT WAN TOU DON'T NOU SONT SAY IT.

Yes 👍 true
2 different fluids 1 massive breaking suspension apparatus
this is for the steering rack the green bottle is not connected to the brakes system .

On other cars they are called brakes, on Jaguars they are called breaks, for a reason.
yeah LOL
any where i can get this related parts ,power brake accumulator,fitted underneath below radiator RH side

olikat8 thanks for sharing! And no Lucas...? Jelli
It still has it's "Character," but much more reliable starting in '90

at 1:10 I show the stuff you'll need.

@@docsgearheadgaming2503 Going Live in a few miniuts I'll talk about it
My 91 xj6 sovereign doesnt have that system, but instead has just the teves mk2 brake system
could u talk to ur jaguar friend and let him know I have a 1988 jaguar xj6 forsale all numbers matching
Philip Rogers you still have it for sell
Can you talk to your Jaguar friends and ask them how the word BRAKE is spelt?
Not how to BREAK something!!!!!!
I couldn't have said it better myself!!!
