Failure Rate of "New Style" Coolant Y Pipe.
#41
So what I don't get: if you guys who switch to 140kpa caps don't see any release from the cap i.e. boiling over, wouldn't that indicate that system pressure never exceeds that threshold? If that's the case, how is a 200kpa cap harming anything? Only thing I can think of is if your car is actually overheating from low coolant, air bubbles, etc. In those situations, the problem lies elsewhere and I doubt the caps will make a difference unless you're overheating it all the time.

Surely you should think of the cap as a safety valve - like an electrical fuse - neither one should be triggered in normal use, there to protect hoses etc. in the event of a problem. So rating doesn't particularly matter as long as not too low. This is a pressure relief cap not a regulator.

I'd rather have my system work up to 200 if that was how it was designed to work...which it was because that is the cap they chose to use. The original plastic tubes were not up to the task....so replacing them with stronger units is best.
I looked at a new F-type and it was 200..so not sure why your dealer gave you 140. And not sure why on some cars it seems to be 140 and others 200...have not looked at other cars but it is possibel the radiator's on larger cars are larger and don't need to go over 140, who knows.
Anyway, just to reasure you that I do fully understand your point and post, just don't agree with the logic. I put metal pipes in my car and now will leave it at 200 as designed given things work just fine now - I don't want to have any overheating issues with the car. Ever. I bought a 140 cap...thought about it...and decided to use 140 would be an error. Just my way of thinking. Best.

Pipe style transition
My MY2017, from what I have found, was built very late 2016. It had the flanged plastic pipes. It's always difficult to know the exact point and car that the change to the solid round pipes was effected. No different than the production changes that E types went through. What was still in the parts bin?? I would say that a mid to late 2017 production F may have those new pipes. I was fortunate enough to have my old style pipes replaced under warranty in early 2022. I also bought a set of the aluminum ones, as I do'n't think plastic and hot liquids together will last long in an engine compartment. There are many threads about these pipes here, take some time to read through them.

The factory pipes are still plastic but improved from the early versions, the later factory pipes are one piece and smooth with no plasti-welded seams down the middle which was the main failure point of the old pipes.
The changeover AFAICT was some time in 2016 and/or with the 2016 MY.
Edit - too slow as usual, beaten to it by Valerie! And the changeover may have been in 2017 not 2016.

It's an interesting topic. We ordered some of the aluminum items from Alibaba to see if it was something we wanted to sell. They aren't expensive but it's the shipping cost that adds quite a bit, so ordering 50 or 100 sets and sending by sea freight makes sense.
Our team had some concerns about the fitment of the parts. The OEM stuff slots into the holes pretty smoothly and square. The aluminum ones were not perfectly aligned and you can push them in but doing so pinches the O-Rings. My tech director and service manager concluded that they were too concerned about the O-ring longevity.

Stuart don't know if your aware but the originators of these make them here in Houston,Texas? I started the first post on these Aluminum replacements and wanted to make VERY sure what we were getting. Now they have been copied all over the place and we are seeing QA issues showing up.
Here is my thread where the manufacturer makes a few posts with some background information. However I will note we are still waiting on the rear water manifold as well as NA versions! Someday I hope!
Aluminum Cooling Pipes
As you might have noticed they started at around $220 or so for the pair and now they are running less than $60 which is great IF the quality is there.
So I am sure Chinese copied parts might have some issues?
Hard to say as I unfortunately paid the $200+ when they first came out. These were nicely made and I have no complaints about fitment.

Not trying to insinuate that they do or don't make the parts in China, just a face value comment that we sourced some identical looking parts that we would be able to sell for $60 and found the fitment wasn't fantastic. Probably not enough to be a real problem but if you have a few problems and the parts only make you a couple bucks, it just isn't worth the hassle.

OK, change of plan as it often gets over 100 F here in summer!
I will fit the new cap when it arrives and run with it through until the start of summer here (1 Dec) then consider switching back to the 200 KPa cap. Whichever way I go I will keep the other cap in with the tools I store in the cubby in the hatch, "just in case".

Certainly I'm aware that A company in Texas has been offering them and they were much more expensive originally. And then dropped substantially in price. I have no idea where they are having them made.
