Picked up a new (to me) 2015 HSE Lux with 48k on the clock. The truck has been dealer maintained but still has the original water pump, t-stat and crossover pipes. At this point would it make sense to have all of these parts replaced? I have to take it to my indy for the state inspection and to have him look at some oil buildup around the rear diff so I was contenmplating having him do the work as preventative maintenence. Also, the eco-start/stop function isn't working because the aux battery needs to be replaced. If I simply turn this function off with the IID tool will it prevent the truck from being "ready" for the emisions inspection?

 

The cooling parts should be healthy until least 70K. You can spend you money however you want.. but not needed. I would baseline all fluids, just so you know where they all stand. Don't have the eco part so cannot help on this. The oil build up would be more worrying than the coolant parts.

 

I do not believe you can disable start stop with the IID tool but am interested to learn if you can. Replacing the battery is easy and cheap (provided you do it yourself and don't order the battery from LR). The spec is widely available. It may require use of the IID tool to 'reprogram' (wrong word) the vehicle/tell it it has a new battery.

 

Thanks. I was able to source the battery from a Local LR dealer @ $265 which is the cheapest I could find anywhere. There were a few dealerships around the country who sold it cheaper but it couldn't be shipped. I do have the IID tool so I should be able to initiate myself.

 

What is the approx cost to replace the water pump, t-Stat and cross over pipes on the 2015 LR4 HSE?

 

I don’t have a good answer on the cost - I seem to remember posts indicating the dealer charge is somewhere around $2500 on a supercharged model (supercharger has to come off). If you’re mechanically inclined, you can do it yourself for around $400 - plenty of posts on landroverworld.org on the procedure.

But I did want to caution regarding the timing of this job. A post above says its not needed until 70K. While I generally agree, that poster appears to own the V8 model (based on his signature). The scV6 runs a little hotter (different thermostat), and I think the crossovers degrade more quickly. I had coolant odor at 50K. No leaks could be found on pressure testing, so the dealer wouldn’t do anything else. So I just went ahead and changed the pipes myself at 52K and they were badly degraded - I might have gotten a little more out of it, but not much. So, I’d say definitely by 70K you should have them done, or earlier if you’re smelling coolant.

 

Thanks so much
I will not tackle that job at all. I do have an extended warranty that should cover this repair.

 

Extended warranties often will not cover this. First, many extended warranties don’t cover coolant hoses and pipes. Even if your warranty covers coolant hoses/pipes, most won’t cover preventative repairs, in which case you might actually have to wait until it fails. Beware, though, that most warranties also have a limitation on liability for consequential damages, meaning if you wait for the pipe to fail and it takes out your engine (due to overheating), the warranty will cover the pipe but not the engine (consequential damage).

 

So yes, and no, it just depends on the policy and company, you'd be surprised how vast coverage and price range in the extended warranty field. What I suggest to my policy holder's on "preventative" maintenance on well known failure points, it to find a local manufacturer specialist, explain the situation and have them take a look, if they have see / can reason replacement, that is all the warranty company should need to hear to accept coverage.

 

I guess the question is, what kind of warning signs are we talking about for the coolant pipes and water pump. Is this something you start to smell coolant, or notice that the coolant is low, or get a warning light, etc, letting you know that you should make the repair asap? Or, will there be no signs at all and all of a sudden you you are driving down the road, lose all coolant, overheat and blow the engine in a matter of seconds with no advance warning. If the latter, it would seem to be prudent to proactively do the repair around 50-60k.
