My biggest worry with the seam welded coolant pipes is that they could fail suddenly, and without warning make the car undrivable, and if your not in a position to immediatly pull over when it happens your going to cook the engine too. Most parts on cars will fail slowly and give you warning something is wrong. The replacement pair of pipes cost £80 and new gaskets £40 new coolant £30 and it took me a full day to take the supercharger off and clean everything up (but I don't work very fast) then half a day to put it all back together. It's not a specialist job really, just basic tools needed. While I had the SC out I replaced the snout couper and SC oil - Another £60
Hardest part was lifting the SC assembly off the engine, those locating dowels were well and truly rusted in place. recommend seeing the thread about waterproofing your engine cover, couple of rocker cover bolts were well rotted and needed replacement.
So really not that costly a job if you don't mind getting dirty, and now peace of mind.

Good preventative work you’ve done there.

I’ve noticed from previous topics that the supercharger assembly can be a pain in the butt to remove as shown here..... https://www.ftypeforums.co.uk/viewtopic.php?f=27&t=4525

What method did you use?

I’ve had no coolant or supercharger issues with my car so far and very much doubt I'll replace the parts unless I see, hear or smell anything that indicates they’re on the way out.

I did notice a small amount of residue running alone the top seam of the lower Y-pipe, I could'nt tell if it's from the coolant or the white corrosion that is on the alumimum components has washed onto it?

As for the method, I worked it on all four corners with a length of 2x2 for couple of hours, yes at least 2 hours I would say, it gradually got looser. There are no good places to get leverage on it with a crow bar unfortunatly, I found using 2 lengths of wood and rocking it front and back most effictive. The service manually says pull it off with a engine hoist, I don't have one!

It’s nigh-on impossible to see the top seam of the original lower ‘Y’ pipe (see green indicator in diagram) with the supercharger assembly in situ. Coolant stains are a yellowish/light brown colour and aluminium corrosion is white.

Apparently, a slide hammer works well to remove the supercharger as shown here.... https://www.ftypeforums.co.uk/viewtopic.php?p=44768#p44768

Or you could have tried Rizwan’s ingenious idea (see pic).... https://www.ftypeforums.co.uk/viewtopic.php?p=44672#p44672

At least you’ve given yourself peace of mind now.

No, I will always worry I got something wrong, it's in my nature unfortunatly.

The deposits were indeed clearly white. A inspection camera boroscope is what you need, Aldi sell them every now and again, about £25 I think it was.

It doesn’t sound like there was anything seriously wrong with your car’s original coolant outlet ‘Y’ pipe but as they say “prevention is better than cure.”

I’ve picked up some great car accessories in the ‘middle of Lidl’ (electric oil pump being one of the best) but hardly ever go to Aldi....I’ll keep an eye out.

Dropped my car in to Jaguar Maidstone this afternoon. Booked in for tomorrow morning. Got a call an hour later. Fault found, split on bottom of expansion vessel. Should get back early tomorrow. Exceptional service Jaguar Maidstone

Glad they've sorted the issue and hope you had the car back on time?

Car back this morning and I got a discount through F Type EC club. Bill was meant to be £348 and with discount £277. It only cost £25 to become a member. I believe you get reduced labour rates and 15% on parts:

Very true Jonm and it's almost daft not to for peace of mind.

I'm not statistician, but I'd be interested to know just how many actual failures there have been?

First up, I'll hit my favorite dealer and see if they'll do it as a goodwill gesture...very much doubt it.

Glad to hear the car was returned on time. If you'd had the job done at a good independent rather than the main dealer, you could have saved yourself a few quid.

Now that made me chuckle.

I’m dyslexic so make a few mistakes typing. I use to get hung up about it when I was younger. Now i can chuckle.

Nothing wrong with what you typed (15% discount on parts), but I do tend to see things a bit too literally sometimes. Sometimes? Always! :lol:

On the other hand, it’s almost daft to replace numerous parts which have nothing wrong with them.

As per the link to the Jaguar technical bulletin I posted earlier in this topic, these include: upper and lower coolant outlet pipes / supercharger gasket kit / inlet manifold gasket / throttle body gasket / engine coolant. Additional tools recommended are supercharger guide pins.

A fair bit of work is involved.....

Remove the charge air cooler
Remove the air cleaner outlet pipe T-connector
Disconnect and reposition the hoses
Remove the upper coolant outlet pipe
Disconnect the wiring harness from the throttle body and removing fixings
Disconnect the hoses and remove the throttle body
Remove the supercharger belt
Disconnect and reposition the wiring harnesses and hoses
Remove the 6 supercharger assembly fixings
Remove the supercharger assembly and gaskets (made more difficult by the locating dowels being corroded)
Remove the lower coolant outlet pipe
Install the replacement lower coolant outlet pipe
Install the guide pins to aid installation of the supercharger
Install new supercharger to cylinder head gaskets
Install the supercharger assembly and fixing bolts
Remove the guide pins
Install the wiring harnesses and hoses
Install the supercharger belt
Install new throttle body gasket and throttle body
Connect pipes, fixings and wiring harness to throttle body
Install the replacement upper coolant outlet pipe
Clip the wiring harness and connect the 2 coolant hoses to the upper coolant outlet pipe
Install the hoses
Install the air cleaner outlet pipe T-connector
Install the charge air cooler

With regards to statistics, in this topic and also the recent one ‘Checking coolant y pipe’ https://www.ftypeforums.co.uk/viewtopic.php?f=27&t=6598 , the only member so far who has mentioned that he’s had the F-Type coolant ‘Y’ pipe issues is Rizwan (I linked him in to show his pics on how he removed the supercharger assembly). In these topics, those that have implied they haven’t had this issue on their F-Types are MajorTom, RPSN, simpleR, Tel and jonm as follows.....

Yes I still have the original parts in my car. No issues here yet either, touch wood.

My car’s on approx 45k at the moment with no coolant issues since I’ve owned it

After 5.5 years and 41,000 miles I'm still trouble free.

7 years no issue. with coolant whatsoever.

Does your car have the original lower and upper coolant outlet pipes or the replacement (modified) ones as shown in this topic?.....
https://www.ftypeforums.co.uk/viewtopic.php?f=27&t=6598

I have the original 'ridged type'.

My biggest worry with the seam welded coolant pipes is that they could fail suddenly

It’s a long shot to try and get the job done at a main dealer under a goodwill gesture (even more so as your car is MY2016) but as they say....."nothing ventured, nothing gained."

If you don't get any joy and are considering doing the job yourself, here’s three excellent links to assist you.....

By the way, what happened to this.....

With that said, for the 100 quid or so it costs for OEM parts, I might do it and the SC coupler as preventative maintenance, however I'm a firm believer in, "If it aint' broke, don't fix it".

I'm on the original parts too. No issues yet, touch wood!

This is also true, and based on the IIIBDFI (If it isn't broken...) principal, for now at least, the original ones can stay.

Hopefully, the lower (Y) and upper coolant outlet pipes will last....all ok so far

If you did decide to replace them yourself, the links I provided earlier are very helpful.

Not good to hear!

At least you had the coolant outlet pipes and water pump replaced under warranty....https://www.ftypeforums.co.uk/viewtopic.php?p=49508#p49508

 

[khyronzz]

Derby not me. 5.5 years problem free is impressive. I am on my 3rd fault in 14 months

I didn't have an issue with coolant leak till 7yrs

Best case is the reservoir tank is cracked

Worst case is a plastic coolant pipes are cracked which requires changing it and not a complex job but tedious as they have to remove the supercharger cover and best to change the coolant pump as well

Statistics. Add me on. 2017 400s. Read all this post and others. Bought from Dealer Jaguar approved, August 2001. Very low mileage, best I could find. Full Jaguar Service History. I did not take on any additional warranty. I changed the oil and filter, checked coolant, it was low, but not enough to trigger low coolant. Decided to swap out the plastic pipes. Signs of leakage from lower pipe.
All done, hardest bit was the lower screw at back of supercharger metal bracket, and of course getting the supercharger off the dowl pegs. All done. simpleR. Reg when purchased was SO17 UAW VIN K47325, any other info would be appreciated.

Went to Brooklands and Newby Hall. I’ll do about 3,000m / year, so just a toy.
