If I were keeping my Range Rover long term it sure seems like it might be wise upgrade given the known issue with eventually brittle plastic versions.

Aluminum crossover pipes (Under supercharger)

Out of curiosity, as I've had these aluminum crossover pipes installed for many miles, would anyone be interested in a set? You can find them used out of 10-12 RR SCs, but they are scarce. Would anyone be interested if I had a few sets made? I already have the CAD files. Being both the...

So the coolant pipes are plastic and made from two pieces and are prone to split on the seam under pressure ?
Made for 5.0SC and the 3.0 TD, is the back pipe prone to split under pressure like the 5.0 ?
Why hasn't JLR made things right?
Will insurance cover this type of failure? sorry for the questions....appreciate anyone time for answering.

 

2016.5 RR 3.0 Supercharged with 51k miles. Mine was slowly leaking and when removed was crumbling where the ends sit in the block. CPO warranty does not cover hoses or pipes so replacing proactively for leaks is on your dime. Warranty would most likely cover a blown motor due to the pipe failure. If JLR admitted it was an issue that would be a lot of repairs. There is a Jaguar Topix bulletin to check the pipes for leaking. Doubt any insurance would cover the repairs caused by this failure.

 

The early LR4/L322/L320 and some 13 L405s had the y pipe as metal. They switched to plastic for some reason (most likely cost cutting). I believe the latest OEM revision has a different design (although still plastic). The failure with the old plastic pipes was that it would split at the seams.

These metal ones would be nice to upgrade to. I still have to do the rear outlet pipe and might upgrade both to metal when I’m in there.

So have you found a metal (aluminium) rear crossover pipe on the market that you'll share with us?

 

My Indy installed new aluminum lower and upper coolant pipes sourced from Northside Imports. Not sure what manufacturer.

 

Inquiring on a separate thread as well - what was the expense with your independent shop to upgrade / replace those pipes? Any feedback on fit and finish on the metal pieces your shop used? I am considering that preventative maintenance before my extended warranty expires.. Having the plastic stock pipe(s) go post-warranty would really throw a monkey wrench in my fantastic, trouble free Range Rover experience to date! haha

 

My Indy charged $1400 for the coolant pipe replacement job with the new aluminum pipes. The quality of the new aluminum coolant pipes looks good.

My 2016.5 RR HSE was also trouble free until about a year ago at 45k miles. Since then I have replaced battery, front lower control arms, original front brakes (rears done as part of CPO) and leaking water pump that were all expected wear/age/known defect items for a RR of this age and mileage. The water pumps are a known issue and can fail at any time.

I could see coolant leaking on the garage floor from the water pump but no apparent leaking from the coolant pipe as it collects in the V of the engine block. Needed a borescope to look down into that spot to see the puddle of orange. Did not get a low coolant warning but was checking the coolant level every 2 weeks and saw that it slowing going down. Replaced coolant pipes and no loss of coolant since.

 

@MtnRover....Great work...better to get to it before you end up on the side of the freeway with blown hoses and possible blown engine.

 

I spoke with several mechanics that have updated these components and none of them appear to have done the aluminum version despite knowing that it exists. Might just be a Canada thing.

 

I’m finding them (aluminum crossover pipes) on the aftermarket sites but would like hear a few other success stories before making the jump. Mine is due soon. ‘17 5.0 L405 SC

I just ordered eBay aluminum crossover pipes, OEM water pump, OEM heater cross tube, OEM supercharger coupler, and OEM thermostat. The knowledge on this forum will keep my supercharged 5.0 from a hot summer day engine failure. This will be a DIY project instead of dealer or Indy.

 

Awesome..Keep me posted on how things Go with the Aluminum Pipes

 

I'm dealing with this same issue now. Our RR is parked in the driveway because the pipes decided to let all of the coolant out. I had already scheduled with our Indy shop to take the car in for suspension checks and a suspension fault error that started showing up. Plus a leak of some sort - I thought it was oil, but it may be hydraulic fluid.

Then, while I was looking over the engine bay, I just happened to check the coolant and the lines. I noticed a little bit of orange showing on the crossover tubes. I drove it to work the next day, and as I was pulling into work, got a low coolant notice. I had just checked the coolant level the night before. Got the car home and coolant was way low. Used a good light and saw a lot more coolant on the crossover tubes. So, called the shop and asked them to add that to the list of things to look at/work on while they have it.

**Edit to add - Our car is a 2014 and just passed 105,000 miles.
