I don’t know how polling actually is tabulated but I’m asking the forum for some understanding of the percentage of failures from owners. There are 40,000 f types manufactured over 10 years for the US market. How many have failed? I have followed all the members who had plastic failures, but when compared to total amount manufactured it doesn’t seem to be significant. Hopefully we will have members responding. I check for leakage on a regular basis on my ‘16 S on top and in the valley. Cheers Frank

 

The manifold pipe on my ‘16 Type has not failed. 90,000 miles. Nor on my ‘17 Pace S. 80,000 miles. Touch wood.

I had it fail on my ‘18 Pace at 85,000 miles and on my XE at 75,000 miles this year within two weeks of each other. Ouch.

 

Thank you for your response. Seeing the number of views and only one response; as of now; can it be they have no plastic failures? I will monitor the number of views and see how many respond to this inquiry. Hoping with the number of members on this forum which attracts worldwide membership we may have a true picture of this issue that has all of us wondering, is it milage or time? Thank you in advance for taking time to reply. Cheers Frank

 

I have a 2014 V8S with 7600 miles. No plastic pipe problems yet. Do not see any leakage.

 

2016 S Manual, original pipes, no leaks (or any other problems, knock on wood)

 

oof, 43K miles. original clutch too

 

My 2018 started leaking at the seams on one pipe in 2022, 16K miles.

 

2014 V8S 58,000 miles. No issues

 

2016 S, 47,000 miles no problems.

 

Thank you all for responding. Reading past posts on this subject with more than 570 replies and over 117,000 views it comes down to very few have experienced failures. This is encouraging with 40,000 F type on the road. I’m guessing from the all the posts listed on the forum a very low percentage has failed, I’m guessing .002 percent. I know this, it gives me a certain piece of mind about a problem with a very small percentage of failure. I hope this helps with anxiety about plastic failures. Cheers Frank

 

Hmmm not sure your data sample is accurate here, lots of assumptions to guess at a .002 incidence rate.

Nevertheless it does help to point out that failure at a lower mileage is not that frequent. So many other factors come into play - I'm sure climate, perhaps driving style (heat under bonnet, perhaps even movement of engine under torque?), etc. have some effect. It apparently was a big enough issue with the early cars where Jaguar did issue updated pipes, so there's that.

Not a sky is falling scenarios, but also not a stick your head in the sand scenario either if you smell coolant, check it out. If you see steam coming from your hood, shut it down immediately. It's not even the fact that it leaks coolant when it breaks, but that your coolant system could rapidly drain leading to very catastrophic effects.

But agree, don't let it keep you from enjoying your cars!

 

2015 R but went ahead and got my pipes replaced at 30k miles.

3 years ago, a group of us (5 cars if I remember correctly) were on our way to Tail of the Dragon and one of the other cars had a pipe fail during the drive. Can't recall what year though.

 

Like most such weaknesses, it's much wider reported than experienced. And, the base is MUCH larger than F-Types, since the same engine has been used in many more models across Jaguar and Land Rover. Of course, it has the potential to spell disaster, but - percentage-wise - it's not pervasive.

FWIW, my MY14 hasn't had any issues, while the MY17 F-Pace S had an uneventful leak at year 4.75 (under warranty, thank you). I have a set of the aluminum pipes at the ready whenever they're needed, or I'm in there for something else, whichever comes first.

 

Our plastic pipes didn't fail, but our slight but constant coolant loss was because of a leaky water pump, which was included in the EURO-Amp kit we had installed. Hasn't lost a drop since.


+++++++++++++++

BUT, often the plastic pipes would fail catastrophically and dump ALL coolant, causing other engine damage! Which was why we replaced our plastic pro-actively.

Perhaps a better poll question would have been,

How many failed coolant pipes have caused serious engine damage?

 

Bfrank, I acknowledge that I made assumptions and a guess at the percentage of failures. There is no accurate data on failures in 40,000 F types and with only this forum to rely on I can only speculate and guess on the percentage. you can read all the posts on actual failures and see how few there is. And uncheel just posted I didn’t include the Land Rover models, I’m saying you shouldn’t put your head in the sand but you shouldn’t lose any sleep over the problem that effects very few motors. I check for coolant leaks on a regular basis but I also realize this is not a very common problem. MY16S with 60,000 miles. Cheers Frank

 

2017 3.0. 61,000 miles. The rear coolant pipe just started leaking.

 

Frank, the situation is this: the original pipes are going to fail at some point. Where you are when they fail is unknown and how quickly they will fail is also unknown. And if a lot of coolant is lost before the engine can be shut down, damage (($$$$) is likely to occur. It really depends on how much of a gamble you are willing to take.

I had the pipes in my F-Type replaced with the metal variety at 54,000 kms without ANY sign of failure, and never any coolant loss (or any other issue!). But I am not a gambler. While this work was being done I also had the water pump and thermostat replaced and the supercharger oil replaced - while these were easily accessible. This work was not inexpensive but the car is too valuable to me to risk damage if it can be avoided.

My son’s F-Pace with the same V6 supercharged engine had the rear manifold pipe suddenly fail (after a highway run) at about 75,000 kms - but it was caught immediately with no damage to the engine. All the pipes were then replaced.

You may never have a problem with the pipes. Or you might….

 

Also keep in mind that people here are only a small set of Jaguar owners…most aren’t members. As mentioned, this engine has been used in more than FTypes. The shop that did the swap for me said they’ve done the work before and knows it’s a common failure point. I’d rather be proactive than risk the hassle and cost of possible engine failure.

 

100% in agreement with you. I tend to think of these pipes (and waterpump, and coolant hoses, etc.) as medium term wear items. They will go at some point, so as with everything else I will likely "overkill" and change my pipes pretty soon (around 34k miles). Not just the pipes under the SC, but all the other little fragile hoses, check the SC coupler, water pump (which I suspect is weeping), change the SC oil, remove the insulation underneath that is notorious for holding moisture, replace any rusty bolts in the valley, etc. All PM stuff, which IMHO is the difference between a fantastic experience with these cars and a bad experience (and that goes for BMW, Mercedes, LR, any high end marque).

 

Agree with this point too, the particular thing about these pipes (and again, main plastic components on other marques that do the same thing) is they fail big. Sometimes it's a leak, but sometimes it's a big gushing failure where folks don't detect soon enough or try to get to that next exit. Then you cook your motor. That's why the aluminum pipes are nice - and folks don't be deceived. The orings on the aluminum pipes will leak over time too, there is no eternal solution here, BUT it won't be some massive issue that evacuated your entire coolant supply in an extremely short period of time.
