My 2009 Jaguar XF Supercharged hit 113,000 miles, i was wondering should i replace these things? Especially the timing chain, if so does anyone know the procedure? Also add to list if i missed something please, thank you.


Drive belt
Serpentine belt
Supercharger belt
Timing chain
Spark Plugs
Brake Fluid Flush
Coolant Flush

 

Where did you get this list from? Is this in the manual somewhere?

Why would you replace the timing chain? Timing chains don't typically have change interval. Maybe you are confusing that with a timing belt. Replacing the timing chain is not going to be an easy task. The timing chain guides and tensioners would probably need to be replace before the chain.

As far as I know the drive belt is the serpentine belt.

The rest you could do without much trouble. You may need to have the supercharger removed and rebuilt soon.

 

That's what I was confused about, I've never heard about the timing chain being replaced. Also i could not find the timing belt, do you know where i could possibly find this. And is there anything else that you think needs to be replaced or changed, thanks.

 

I was trying to state that typically a timing belt needs to be replaced but a timing chain doesn't. The 4.2L SC has at timing chain. It does not have a timing belt so you don't need to worry about it.

 

Ok, thank you. So should I go ahead and change or replace the rest of the stuff?

 

Timing chains do stretch but, should be good (as long as you do regular oil changes) out to 200kmi, as should your harmonic balancer and drive shaft. 100kmi is probably super charger service time though.

 

As stated before, I think the drive belt and serpentine belt is the same. If it original, I would do an intensive inspection, but probably would replace it.

Don't know about the SC belt.

The timing chain should be OK, but I had the one in my car replaced, along with all the related tensioners and other parts. I had thrown a code which disappeared. Fortunately, it was done under warranty.

Brake fluid flush. If not done, definately do it. Same with coolant.

I would also have the car scanned for any pending codes that have not yet triggered the check engine light.
