How are you, my mother owns a 2011 5.0 V8.

She has 100k miles on it, I'd like to know what major preemptive maintenance I should do.

The fact that she has Factory shocks, Factory Spark plugs, and Factory timing belt(chain?) is keeping me up at night sometimes.

Couple Of questions.

1. Timing chain or belt?
Chain (Thanks DPK)
2. Time for spark plug change. iridium?
Every 100k miles
3. Tested shocks, bounces right back, no play.

4. Differential fluid flush?
Every 50k miles (Thanks DPK)
5. Transmission fluid flush?
Every 30-40k miles (Thanks DPK)
6. Fuel filter?
Every 50k miles(Thanks DPK)

Aside from the simple and routine(Oil, filters) I've flushed the coolant, and brake fluid with the last brake job(94k miles).

I'm mostly paranoid about the timing belt/chain, since this is usually the mileage it needs to be changed at.


I've used the search function, nothing came up about the timing belt/chain

Thanks in advance.

EDIT:

I'm Gonna Edit the information provided so other members can search and see.

 

Check the owners manual for the factory specified service schedule. The information can also be obtained here: https://www.jaguarforums.com/forum/x...ownload-10581/

 

Your maintenance efforts are commendable..

Per my Certified Jaguar Master Technician and friend of mine..

Plugs; yes, use Jaguar plugs

Timing belt; is a Chain..sleep easy.

Transmission; is long over due..Should be flushed and conditioned /with refill every 30,000 to 40,000 miles,

Rear Differential; long over due..should do every 50,000 miles.

Fuel filters: long over due..should do every 50,000 miles.


You might want to also change the Cabin Pollen filter and the engine's two intake filters and douche' with the appropriate cleaner, the two MAF sensors.


The Maintenance schedule in the OM is the bare minimums to meet the warranty period without major issues..

A savvy person will cut those OM periodic maintenance times in half to enjoy longer life from these cars.

 

Pefect, exactly what I was looking for.

Ok, so the chain is great. I just wait until it starts making noise, or the tensioners start knocking.
I did both the air fliters, and the cabin filter. I did not replace the MAF sensors, nor clean(douche')anything out, since everything looked relatively clean.

I'll tackle the differential, Tranmission, Plugs, and fuel filter over the next weekend.

The car still drives like a beauty(back when I first drove it at 15k miles, when my mother first bought the car, craigslist is amazing sometimes)

This car has been trouble free all it's life(except this one time the radiator fan blew apart, but was covered by warranty)

Thanks again for the info.

I think I saw a few threads about the differential and the spark plug(which, holy crap looks annoying, due to the space constraints)
You think I can find some info on the fuel filter(should be easy, just like any car, right?) and the transmission?

Should I take anything to the mechanic, or it's all relatively DIY-able?

 

Make sure you use the correct fluids for the transmission and differential.

Any old generic transmission fluid will not cut it, must be genuine ZF Lifeguard or equivalent. For the diff there is a Jaguar/Ford spec synthetic fluid which is not always easy to find.

Cleaning the MAF's is an easy enough task.

For me i'd also be thinking about changing the upstream O2 sensors, if not all of them.

 

+1.....Also good advice~

 

Care to elaborate on this? Mine go out frequently and if there was a regular cleaning schedule I could follow that would be wonderful!

 

Our XF's uses a T20 Torx bit for the mounting screws...takes a whole 10 minutes to do both.

 

Could you point me to the right fluids?

Which fluid do I need for the transmission, how much of it
Differential, how much of it?

Thank you.

I looked around, a lot of stuff seems to be on the MODERN jaguars.
I have not yet seen any guides on the current xf.

 

The 6-speed ZF transmission in a 5.0L XF is close enough to the same as the other 6-speeds in earlier model Jags (not to mention the other makes that run this tranny).

If you find ZF Lifeguard 6 that'll be it. Same quantity as the other/earlier cars too.

For the diff yours has the GKN rear axle which uses a different oil to the earlier cars. But seems Jaguar also changed the oil specified for the GKN at some stage as well.

There is a different oil specified from VIN S61362 onwards.

 

Coolant change time too!

 

Yes and replace the thermostat too while you are at it.

 

Yes, I forgot to mention that was changed when the radiator blew out, and last I checked it was still good pink color.

 

https://en.wikipedia.org/wiki/ZF_6HP26_transmission

Is this the proper transmission?

EDIT:

Can I use this kit?
http://www.thectsc.com/products/oil-...ce-186-50.html

Edit 2:
My Vin SAJWA0FB8BLS14981 , S14981 is younger or older than what you mentioned?


I'm sorry for pestering you, but it seems you're my only source of info atm.

I'm also editing the OP with all the information I find to make it easier for future users to find.

Thanks again

 

Yes that kit from ctsc for the ZF 6HP will be fine.

OK so the specified oil for your diff with VIN 14981 is the Jaguar C2D3653 which apparently has been replaced by the C2P25272 from the later models anyhow. Should be like $35 a liter from a Jaguar dealer. I think it's Castrol SAF-XO Synthetic Differential Oil.

 

Thank you for that part #


Yes it appears to be that castrol oil.

EDIT:

Appears I can't edit my original post.

You think there'd be any problems of me doing another post, with all the compiled info?
Or would you like to add this to the already stickied post?

A lot of good info here for the current x250 owners.


Thanks again!!
Ordering everything, hopefully fully serviced by next weekend.

 

I've never heard of arbitrarily changing these,why do you recommend changing all of the o2's if you're not getting any trouble codes?

 

Castrol Syntrax Longlife 75W-90 Multivehicle Axle Fluid 75W90 1 Litre 1L | eBay

Is this the correct differential fluid??

https://www.fcpeuro.com/products/bmw...t7pRoC4vzw_wcB

Is this one ok? I contacted their customer service, they did confirm it is CASTROL SAF-XO, just a diff label?
Proof:

Apparently SAF-XO was renamed to Syntrax.

Anybody can close this topic out?

Let me know please, if the links I provided above are for the proper differential fluid.

Thank you

 

I'd suggest that you're getting the opinions of one or two owners as to what should be done when (on some items), not universally agreed upon task intervals specified by Jaguar or ones determined by the majority of owners.

Changing fluids more often than specified usually does no harm (other than mistakes made during the change) but there's a big difference between feel-good intervals chosen at random and factory intervals that have some substantiation behind them.


PS: not interested in a debate involving personal attacks that result in yet another post getting locked.
