My limited understanding is that early V6 F-Types had Y pipes with seams. Had this change by the 2018 model year?

 

I have a 2018 V6 and the Y-Pipe failed at the O-Ring ends that extend down into the valley openings. Probably good not to just focus on seams.

 

Late 2018 model year builds had the updated coolant pipes. I don't think the exact date is known though when JLR started installing them. Best to check. My May 2017 build MY 2018 has the seamed pipes.

 

Thanks guys looks like the safest thing to do is install the metal pipes.

 

My local jlr dealer updated my coolant pipes to the plastic seamless ones on my 2016 V6 base model with 44k miles about 6 months ago and so far no problems, FYI.

 

I have a 17 S AWD coupe and I just updated all the original 2 piece seemed plastic pipes to Aluminum and even new water pump with new aluminum water pump to oil cooler pipe. No leaks prior to doing so. AND NOW THE BLOODY THING IS LEAKING!!!!!! AARRRRRGGGGGGGHH.

 

Thats annoying, can you tell where its leaking from? If you have time part numbers and sources would be useful. Especially if you have a defective part so I'm able to avoid that manufacture.

 

Seems like many are experiencing leaks after the aluminum conversion coming from the small connection pipe that goes from the water pump to the oil cooler. Some have reopened everything and gone back to plastic for just that small pipe. I guess I got lucky when I did mine and the alum. one worked for me. When I do jobs like this one I'm meticulous using O-Ring lubricant on all rubber seals. I find this little extra step can make a difference in the way O-rings seal up.

 

I was an early adopter of aluminum pipes and have had no problems. Did water pump at same time. Done by my indy.

 

Yeah I have read those pieces along with the heater pipe can sometimes be defective and leak. A real bummer - when I upgrade I will probably just use the plastic parts for those.

 

I think that is likely the cause of my leak so im hoping they can get in there and replace that with OEM plastic without having to do more then take the water pump off, intake pipes, and such.

 

Just a heads up never use the plastic tube
