Hi everyone,

I'm back again with my third post in a relatively short time. I had taken my car (2013 XF SC) in to the dealership to get a new O2 sensor as I got a check engine light that pointed to an issue with the O2 sensor. While fixing this, they noticed that there is a coolant leak via the rear manifold. They said they will be replacing the plastic manifold with an aluminum one as it's more durable and it's the direction they've received going forward. The quote I received is for approximately 2000 USD. I'm not sure if this is high or if it's expected because of the work involved. So I just wanted to check in here to get some more opinions. Thank you for your help!

 

If your vehicle is fitted with the AJ133, the supercharger must be removed to gain access to the heater pipe between the cylinder heads. If they plan on replacing the plastic pipe with an aluminium version, have them let you know the price of all the parts involved.

The price quoted of $2,000US from a Jaguar main dealer is probably comparable to what other JLR main dealers would be charging for such a repair.

 

Thank you for replying and letting me know about this! I was dreading this but was hoping I was wrong about the SC being taken out to perform this repair. In your opinion, is it even advisable to go to an indy shop to get quote? I'm trying to be wary because of the fact that the SC would have to be removed and I'm not sure how many of these places can actually do it without breaking something else in the process.

Also, I'll get a quote of the other items in there too since they already have to take everything apart. Would you by any chance know what other components there could be? I know they replaced the water pump a few years back because of a leak back then but I'm not sure what the other components are.


Thank you!

 

You didn't provide the number of kilometres/miles showing on the instrument cluster, but with the supercharger removed, the supercharger oil should be changed and the snout coupling inspected for wear. Depending on the amount of carbon deposits on the back of the inlet valves, it would be also an opportunity to clean them by means of walnut shell blasting prior to reinstalling the supercharger.

Any coolant pipes on the engine made of plastic should also be changed out to the aluminium versions. Especially the water outlet pipes under the front of the supercharger.

 

You can contact the local Jaguar specialists in your area and ask for a price quote.

 

NO More than $600- 800 dollars in labor

 

I have around 110,000 miles on it. Oh, so the supercharger is going to require some work too then. I'll ask them about these things and see what they say. I might as well get it done now like you said as I don't want to pay for additional labor later.

 

Yes, I've called a few places and I'm waiting to hear back on them. On a side note, just asking as someone who doesn't know anything about these systems, would the battery have to be disconnected to do this work? I'm just asking because most of these shops don't seem to know the exact procedure to disconnect a jag's battery and it ends up bricking the car (happened to me) which only the dealer can fix.


Thank you!

 

Wait really? Even if I say the part is less than $500, this would bring the total to around $1300, quite a bit of difference from the $2000 they quoted. I'm really confused now.

 

So I just heard back from a shop and they said they can do this for $500 and the battery wouldn't have to be disconnected. They said even if the battery has to be disconnected, they would put a "battery saver" so the car still has power to it. This is really low compared to what the dealership quoted and I'm a little wary of it. I also asked if this involves replacing the supercharger and they said that they could do that as well. Sounds too good to be true.

 

No help but glad to see they are using the metal versions. Especially if this was a Jaguar dealer?
No need to replace the SC unless you have problems. Do follow what was posted above by NBCat as I will guarantee the oil is nasty and very low by this time. Most people use the standard ACDelco SC oil which is available just about anywhere.

You did not mention it but the SC snout has a well known "clunk" sound on engine shut down as mentioned above and now would be a great time to swap that out.

One other item which is cheap but a SOB to change with the SC on are the PCV diaphragms. You neglected to tell us which engine you have so again this leads to incorrect advice. The 6 cylinders have 1 and the V-8's has 2 diaphragms.

Next and it's up to you but many of us have removed and blocked off the Symposer stuff. Again your right there so little to no added labor.

In Connecticut its 600-800 out the door if you want only the rear crossover

 

So I've been trying to get in touch with the dealership for 3 weeks to get an updated quote and their customer service has been lackluster. Finally got a quote today with the other parts that could be replaced according to them:

1) Rear Manifold : Around $1400, they actually brought this down from $2000, was a shocker for me
2) Cooling system renewal package (according to them) : Around $5800. Labor is 14 hrs they said. This contains front and rear coolant manifold, water pump (got this fixed in 2019 I believe because of a coolant leak back then), thermostat housing and expansion tank (I believe I got this replaced as well along with the sensor as I was getting a coolant low error back in 2019 too I think).

My question now is, do I need to replace the thermostat housing (since I already got the other ones replaced before)?

I checked with them about the oil in the SC and they said there's no separate oil as it's the engine oil that goes through it. Is this correct?

I will check on the SC snout, this may have been replaced too on mine a while back. This was before they had to replace some other components (or the entire thing?) on the supercharger back when it was still under the extended warranty.

My car is a V6 SC. I can check on the PCV diaphragms too.

The symposer, is it just to enhance the noise? If so, I'm good on that as I don't really care about it much.


Thank you for your help!

 

Wow, crazy what the difference is. They did get my quote down to around $1400 but that's still a lot more that you mentioned.

 

Wow! If the dealer claims the SC uses engine oil they are completely clueless about SC's in general and even more clueless about Jaguar SC's. 100% the SC has and uses separate oil and there is NO connection between the oil in the engine and the oil in the SC! You will quickly ruin your SC if you fill it with engine oil.

Again as I posted above use the correct AC Delco SC oil. It's cheap and available nearly anywhere. Get it changed as it does need it.




You need to listen to your engine on shut down to see if it has the snout noise. Turn the radio off and open the drivers door with the engine at idle. Now shut off the engine and listen. It will be obvious if you have that noise. If you want to be 100% sure then remove the SC belt and do the same thing. With no belt the SC can't make any noise. No this won't hurt anything either.

If you had all those parts replaced in the past I can't say if they need to be replaced again or not. $5800 is a massive bill so it's up to you. Do you have any paperwork so you can see how long ago this stuff was replaced? If it was 2019 that was 5+ years ago.

Yes the Symposer is just an add on device and no harm if it's not removed and no harm if it's removed. Again up to you. I removed mine but since I do all my own work it did not cost much to do.

I will go back to them and tell them about this. Kinda surprising they don't know this info (makes me think the service advisor just said something without confirming). Thank you for the picture!

Yes, I'll check the sound of the snout and see if I can hear it.

Yes, I was going to check my paperwork and see when exactly these were done. Regarding the parts, I just meant the thermostat housing. Is that something that needs to be replaced as well?

 

My comment may sound funny, but I think this is fair for the amount of labor that is needed.

Why is my comment funny?

I was quoted $1400 (Less) and had the work done and I really thought that was cheap.

The fact does always remain, when that (crossover) pipe is failing, it needs replacing or it can lead to an engine replacement.

 

Is the difference that, Deniss is saying "part" and you are quoted "part and labor?"

I'm reading through and maybe this is happening.



P.s. Still I watch a Dennis video once a month.
(Thank you)

 

I'm with you about $1400 for just the rear manifold. The initial quote of $2000 seemed high. Yes, definitely something I don't want to push out.

Also, did you get any other components fixed when they had the supercharger out? I asked them about the front and rear together and they said that would be around $2700. This one seems high as it means they are charging me $1300 just to do the front manifold.


Thank you!

 

I thought so too but he said $600-$800 out the door, so I assumed it's parts and labor.

Does Dennis have videos online?


Thank you!
