I am getting ready to head out of town over Memorial Day and want to make sure I do not have a catastrophic break down. My 2015 Range Rover HSE V6 supercharged has 92,000 miles on it, and uses a very small amount of antifreeze. I finally found a very small amount showing the orange color on the back passenger side of the engine up above and so am going to attempt repair the problem. In reading the forums, I assume with 92,000 miles, several of the plastic parts having to do with coolant have been replaced, but if not, what would you recommend I replace to make sure I don't have a major breakdown on the road.

According to the dealer my problem is "REAR COOLANT OUTLET PIPE WITH COOLANT $2040.41", but doesn't give any details for me to know what they would be doing. I am assuming they are replacing part LR109401 or LR122710, but don't know for sure. Anyone have any information on this?

Thanks

I recommend to do both the rear and front coolant pipes. If you plan on keep the car longer term, I'd consider doing the water pump and thermostat. I would get this work done as soon as you can to have enough time to see if there are any leaks or issues after the work has been done but before your trip. I would inspect it often and carefully before your trip. If there are any leaks, if coolant is getting low, get it inspected.

If the battery is old, like more than 3 or 4 years old, consider having it tested and possibly changing that out as well. I would probably test the alternator at the same time but I'm assuming it's probably still fine.

Check for any oil leaks and assuming it's all dry, I'd either change your oil if it's about time or at least top it off before your trip.

Lastly, check your tires for leaks, even tire wear, and correct pressure.

Absolutely get the work done as Portlandlife has suggested. It's much less expensive in the long run than an engine and much less inconvenient as well.

I agree that the dealer has properly diagnosed.
Do front cross over, rear manifold (i.e. rear crossover), water pump, thermostat, that assembly that contains the small plastic tube that goes into the water pump, intake manifold gaskets, at a minimum, if possible also supercharger oil, supercharger coupling - although the dealer almost certainly won't do those last two.
I am starting this project on the 2016 on Monday and all my parts total to $1050. If a dealership does it, it will most likely be about $4K.

If you are driving with a known leak, you need to be a "soft" driver and if there is any sign of a coolant leak get it turned off immediately.
