For me im going to go for every 50k or 10.yrs whichever comes first for:

Gearbox and Diff oil
Supercharger oil
Power Steering oil
Water pump and plastic attachments
Header Tank
Hoses
Belts

Difficult to know if that's right but im just going for preventative maintenance and ease of work

 

I'm thinking 10 years for any fluids is much too long.

My guide would be 3 years for starters and then:
1. 30k for trans fluid
2. 50k for dif, brake, PS and coolant, battery
3. 100k for belts, hoses, WP, plugs

 

I get your point on time of fluids, your hoses and WP though, they have been recorded as failing from 50000 miles from what I've read.

Im also not sure about trans and diff fluid, I think Mercedes have 50k service intervals for the same box.

For gearbox and diff does it degenerate with age, and within 3 yrs? I wonder the same for supercharger oil and power steering- i think you could be right for those because i believe they are quite thin.
Its an interesting debate, wonder what other people think?

 

The trans fluid is mineral based not full synthetic. It will definitely breakdown over time and use. I replaced my trans fluid at around 18K miles on my 2014 XKR with OEM Jaguar transmission because it would be around 7 years old.

 

Trans Fluid pan and filter are recommended by the manufacturer (ZF) already. As of 8/2013 they changed their recommendation from sealed for life to the following -
" ZF automatic transmissions are filled with specially developed semi-synthetic oils.At very high operating temperatures, the oil ages faster than under normal conditions. Examples:
􏰀 Many trips at high speeds.
􏰀 Many trips with a trailer in tow.
􏰀 Sporty driving.
Depending on the driving style, ZF therefore recommends a transmission oil change every 80 000 to 120 000 km, or after 8 years at the latest."

Change the differential fluid every 2 years because it's cheap and easy but I'm NOT talking about the E-Differential. I have no experience or knowledge there.

Brake fluid changes are recommended every 2 years by Jaguar I think but what you're really looking out for there is moisture in the fluid so using a simple $3 tester will help you decide when to change, assuming no other contamination.

Coolant every 5 years per Jaguar - should be no exception on this given it's OATS fluid. All the techs on this site recommend replacing the entire thermostat housing at that time as they are plastic and get brittle. I agree.

Belts - I inspect them for cracks and slippage - no cracky, no slippy, no changy.

Plugs, every 100,000 miles.

Power Steering fluid? The world can't agree on that. I change it when it starts looking dirty. Anywhere from 2-5 years. I don't drive it enough to use mileage as a guide.

 

My xk has 93000 mil. I hope this does happen to me.

 

?????????????????????????
Seriously???????????
Okay, I'll take yours for a week, I'm sure I'd be able to blow your engine for you.

 

I meant to say, I hope this doesn't happen to me.

 

I got it when I read your post. No worries my friend. We all make silly mistakes.

 

Just a note on the E-diff fluid change. It's no different than any other diff. Just use the correct fluid. I did mine at 40K on my 2014 XJR and it needed it. Thankfully Jaguar finally got a least something right and E-diffs have a fill AND drain plug!

I get real tired trying to suck old funky fluids out of tiny fill holes because manufactures are saving a buck or two by deleting drain plugs!
Not thinking of service/maintenance in any way.

Amazing work! I did notice that new expension cap tank was rated at 200kpa and I believe this is not correct one for your car. Probably not a biggy but I would replace with lower 120 kpa is the correct one on your car.

 

you dont worry about that, it's all in hand.
Besides, if you were paying attention in my walk around videos, you would see it has the 120 cap on.

 

Maybe british English comes of a bit different but for a second I thought you sounded like an *** there.
I seen the 200kpa cap on your photos and was trying to help is all , seen many expansion tanks replaced and most come with higher rates caps which get overlooked and left on ...

 

Like I said...

 

not trying to come at you in a negative way or nothing so you won't go getting offended,but I see exactly why your jag started overheating bro.Jags are not meant to use the Green radiator fluid.For some reason,Jaguar clearly states it needs the lifetime radiator fluid and that green type radiator fluid expires too quickly or simply jaguar engines are too powerful and will prematurely use up the life of green radiator fluid quickly.My guess is any type of engine problem will throw off the timing of the Jagand if your jag dont work even when you fix it back,the timing is gone be the problem

 

my guess is the green coolant made it overheat.Green coolant are not meant for these jags and it looks like the engine made the green coolant get to hot and it started busting rubber pipes

 

my god, yet another 2! who cant be asred to read the thread
The green was already explained, and had nothing....nothing to do with the engine blowing. God I really regret posting this thread. I would be quite happy for the mods to delete the thing. As the saying goes " no good deed goes un punished ".
Forums ey.

 

Thank you for your experience and advice in engine building. I will take it on board thank you.
Now I advise you read the thread, there is so much you might have missed.

 

Anyone else notice that after two months of this thread being established. The critic's are slowly coming out of the wood work with false information. Is this how it goes?
I am so happy that I have been one of the first to post such information on this forum, I am happy that I have indeed helped many both now and later on down the line.
This will be may last post on this forum, I can see were it's going. Oh and no the door wont hot me on the way out. So let the attacks begin. C ya .

 

Yes it's brilliant the guy just pulled the heads off his ajv8 - resets the timing of the valves and you guys are going to point out useless facts to him ...I'm pretty he's got things covered when it comes to maintenance of a engine
