L322 DIY Full Service

Greetings,

Apologies if a post already exists, I had a look without success. Point me to one if there is one.

Looking to do first full service on a 2006 L322 petrol V8 (Jaguar engine), non-SC, with LPG. First time for me doing a service as well (engine plugs and oil, filters, anything else?).

I could only find a video online for the BMW M62 engine (so pre-2006 update). Nothing for the later model. I do have a copy of the Workshop Manual: System Description & Operation, but nothing there. I do have IIDTool as well.

Would really appreciate guidance on how to, tips and tricks and guidance re where and what parts to order.

Thank you!

Not much help but I'd think the service is the same as any other car just different oil/filters?
LPG servicing will be specific to the parts you have, you might find a kit available. Usually just online filters but seals and diaphragm might need doing for peace of mind if they are old

Bit awkward isn't it cuz yours is a changeover year I think, maybe check the 02-05 workshop manual as well?

Try searching with aj41 instead of 4.4 as well

Assuming you've got the 07-10 manual, have you looked on the fullfatrr site wiki?

Prob v similar to the 4.2 s/c but think more oil capacity on yours

@Henry_b will be the man for this

Might be a good idea to change the gearbox & transfer box fluid and the diff oil while you are at if they have not been done for a long time.

Shouldn’t be too bad to do, iv just done a full engine service on my 4.2sc yours will be similar, no manual needed, just look in manual for oil capacity, mines 7.7l, filter is tucked up behind radiator/ front of engine, take both plastic under trays off for access, if it’s like mine it looks tight but when your in there there’s plenty of space. If Sump plug is same, exists side on instead of straight down have some cardboard wedged in subframe otherwise flow of oil pours out, hits subframe then covers your driveway and completely misses the container! Spark plugs, remove engine cover, 3x 10mm on mine, unclip other side covers and that exposes spark plugs, they are the long life ones so depending on when they were done or miles you may not need them, I pulled the two easiest to get at out on each bank and they looked fine so have left them.
Front and rear diff is same as always, drain then refil until it runs out of fill hole.
Hope that helps, I know yours is 4.4n/a but I’d imagine jag used a similar engine build for both 4.4 and 4.2sc.

Thank you all!

@1988smithy I can confirm for sure that it is awkward because of the change year... For example, my fuse box schematics seem to be very custom - no existing documentation matches. Unless someone went in and rearranged it (god knows why one would, so doubt). Good point re code search. Will keep looking.

@Datatek , I have done the diffs oils changes recently. I might add the transfer box change whilst I am at this. For the gearbox, I am soon approaching 140k, so will do full flush for it and associated changes. Will go to professionals for that.

@rich28uk Great, thank you. It seems to be very close to the M62 engine video I saw. Yes, assume not much difference between the NA and SC. I will play it safe and will change the plugs, so I know what is in and when it was done.

Now, I am just going to try to find the right torque settings. I try to do as much by the book as possible. And start building the shopping list for the parts. I was told to better get the NGK plugs. The rest I may as well get OEM.

Hello! Sorry for reviving an old post.

I have the same 2006 L322 petrol V8 (Jaguar engine), non-SC but no LPG conversion and looking to service mine by myself as well. I am into 2nd year of my ownership and I had a minor service done by a LR specialist when I first got it last year.

I am contemplating if DIY servicing will be sufficient to keep the car in good condition? Most item mentioned in this post, such as engine oil & filter change, diff oil, transfer box oil, seems manageable to DIY for me. I might want to try the gearbox fluid and sump pan change too (not a flush, but please do warn me if you think it is better left for professionals). I have replaced the thermostat myself and it went alright despite taking me some time, definitely good experience and learning. But reading through the service item from schedule also include lubing wheel hub, swapping wheels, and some other item that I am not sure if important or not. For example flushing brake fluid and the bleeding process do seem intimidating to me. Coolant flush as well, although I had refilled almost 2 litres of coolant when I replace the thermostat anyway.

Would like to hear your thoughts. Cheers

Never heard of lubing hubs, definitely nothing there to pump grease into, unless it’s meaning wire brush and copper grease on front of brake discs to stop wheels seizing on.
Tyre rotation is just for even wear.
Can’t say iv ever flushed brake fluid, iv topped up after changing calipers etc on other cars but it’s one of them items that does get left a lot. If you have time then do it, just bear in mind seizes brake nipples, corroded pipes etc, check all brake system is worth flushing before doing it, rear pipes are common to need replacing. May aswell replace them then do fluid.
There not bad cars to work on really, sometimes people are put off with the size of them but most of its east enough.

Re flushing brake fluid, I've heard of energising the abs pump during the change.
It can stay full of old fluid, depending on design, if it never gets used

All pretty straightforward except the gearbox has to be filled at the correct temperature.
I always swap the wheels front to back at every service, keeping the wear even places less stress on the transmission.
Regular brake fluid changes are important, brake fluid absorbs water which can lead to corrosion.
Draining and replacing the coolant regularly is also a good move, personally I don't bother to flush.
