I've had that thought all along, which is why I am doing it this fall at 8 years despite the <50k miles.

I just changed my front and rear crossover pipes a few months ago. My '10 RR HSE V8 has 55k miles. From my research, the crossover pipes can fail without notice based on age and/or mileage. The plastic welding just doesn't hold up. Like many others, I see it as a maintenance item every 50-60k miles. Parts were about $200. Indy shop quoted $1,000.

Question for those in the know on this: is the front crossover pipe referred to as the “front coolant outlet pipe,” by any chance? The water pump was replaced on my 2011 LR at 82k miles (86k on it now) and the service record at the dealership has that listed as an item that was done.

I believe the front crossover is sometimes called the coolant outlet pipe. However, the water pump also has a little tube that goes out the back and connects to the oil cooler. This tube also is sometimes called an “outlet” tube and is always replaced with the water pump.
Your service record should have the part numbers listed. If not, you should be able to call the dealer and have them figure out the part numbers. That’s the only way to be sure. Post up the part numbers and the forum can tell you if they match up with the coolant crossover.

I’m probably gonna get criticized for this but I just turned 100K on my 16 LR4 w/HD and I have not yet replaced my from crossover/manifold yet. I had the rear coolant manifold replaced last year due to a leak. I’ve been contemplating the front replacement for several months but my Local dealer service is not great and my indie is ok but takes forever and would rather work on German cars...and I’m not a very good auto DIY guy. My question is: does anyone else have a high mileage LR4 where the crossover has not been replaced?

Mine appeared to be original when I replaced it at 140k. (MY11)
Service records also did not indicate that it was ever changed.
That said, one persons experience should not be used as a guide when the majority have issues at lower mileage.
id say 60-80k is a preventative interval.
100k is pushing it.
anything over 100k, id be worried.
risk vs reward is hard to justify when the risk is pretty much totalling the car.

It is a pipe that rots away, creating a leak, that causes a nearly immediate overheat. Once these engines overheat, they are paperweights.

For some, it seems to start slow - smell of coolant, start looking with a flashlight, find some in the valley, etc. For others, it seems to have just burst wide open on the road giving not even enough warning to shut it down before overheating. You’ll see both types of stories on this forum.
@ScottK - if you’re rear manifold was already leaking, that’s probably a good indication that the front needs to be changed. Both are plastic pipes that suffer from the same problem. When I changed mine (preventatively, 2016 model), the front was clearly degrading faster than the rear.
I’m actually really surprised they didn’t do they front and rear together. They’ll usually pull the supercharger for both, and I would think they’d do both while they have it apart.
