Jaguar F Type Y-Pipe Coolant Leaks! | Is Your Car At Risk Of Major Coolant Failure?! 

Love the channel but that’s not what I expected. 1/ You said “we’re going to have a look and see exactly what’s on this car” and then didn’t actually show it. I know it’s hard to film but come on! 2/ “Massive coolant leaks” isn’t what usually happens. The pipe usually cracks at the flange into the top of the engine and starts to weep, causing the engine bay to smell of hot coolant and a low coolant light on the dash. Many Jaguar specialists (including Tom Lenthall) advise to not worry and just drive the car until you get the symptoms! Many older cars (including Harry Metcalf’s Project 7) are still on there original y pipe. I agree with you that preventative maintenance is important, however the jury seems out on whether to panic about older cars with the two part pipe. I hope that’s not too negative about your video but I just wanted to give it some balance.

That's brilliant, exactly what I needed! I'll check mine tomorrow. Thanks for the video 🙂👍

The trouble is the most common failure points on the pipe isn't actually the seam. It's at the point where it locates into the cylinder block. That's why we install our aluminium upgraded pipe set. It looks like you have the pipes that are prone to failure Mr GB!... You should come along and I'll show you how to install a set of aluminium pipes. Lifetime fix 🤟

I really don't think it's a simple fix at all, and will not be cheap at the dealers. The supercharger has to come off and in every video I've seen the dowels are rusted making it a right pain to get off

Your car doesn't seem to have the revised design, at least not for the upper outlet pipe. There a two y-pipes - the upper outlet pipe and the crossover pipe under the supercharger. At 2:19, you can clearly see the two-piece design still on the upper outlet pipe, so there's a good chance the crossover pipe also still uses the old design. I suggest you replace both (see part numbers below): - Upper outlet pipe (AJ813917) - Crossover pipe (AJ813865) It's also recommended to replace the water pump and the heater pipe as part of the job. I replaced all on my V6S which is now stage 3, and have been driving it hard ever since with no issues. Good luck!

Had mine done while they had the supercharger off doing something else, and yeah it's pretty straightforward but it is labour intensive, and that's why it's expensive. You're probably better off finding a decent Jaguar mechanic rather than a dealer if you want to keep labour costs down a little bit, or get it done while they're doing something else essential that means the supercharger needs to come off, because that's where the cost is.

mine is a 2018 model and I had a coolant leak recently but it wasn't the Y pipe. The coolant tank itself had actually burst. It cost me £130 to fix it all-in. In terms of the symptoms, there was steam coming out of the bonnet towards the windscreen which smelt weird and the coolant level dropped by about 500ml per day.

That's good timing, my dealer said I didn't have leaks but my 2019 r had the old kit. I bit the bullet and replaced the whole system for 3400.00 US. I question why my 2019 had the old stuff. And why jaguar doesn't cover this under warranty when they know the parts suck.

It’s not an easy fix , the supercharger has to be removed to get to the Y piece, an expensive job , had it replaced on my previous 3 litre F type

Love the channel….. but the new revised / redesigned ones are failing on the connection ends. The plastic ends are being reported to get brittle and crumble, fail and leak…. The only real fix is the aluminum ones. I changed my V8S to the aluminum ones, peace in mind.

Per my invoice preventative coolant job: replace outdated cooling components. Mine is a 2019 f type r. Pipe heater, water pump, tube, seal, tube, pipe- outlet, plug-blanking, thermostat, tube,tube, hose, gasket- intake, gasket, gasket, antifreeze@ 10 total cost 3277 before tax. Hope this helps. Jaguar makes a beautiful car, but they suck on customer service.

Happened to me too

Love all the helpful information as I am looking at 1 as I watch ;) Thank you

My dealer has quoted me $4500 to fix this leak.

My experience of owning an older version of this engine is all the pipes crack and fail when they age.

That copper trim is choice.

Ehm bro you have the old upper y-pipe so you also have the old lower y pipe aswell. I have the same F Type R like you, modellyear early 2018 with no OPF and Small navigation...

I looked and I did have the seam pipes , but i thought they upgraded them around 2017. So why did my 2019 have the crap pipes. Jaguar is dying anyway. Going electric. But i paid for the fix for peace of mind because i love this car.

What dates are important here. What defines early vs. later?

okay and what does it cost to get it fixed from the dealer?

A SIMPLE FIX? REALLY. LETS SEE A VIDEO ON YOUR SIMPLE FIX PLEASE.
