Repair Range Rover Sport Coolant Leak

Watch how to fix a coolant leak on a 2016 Land Rover Range Rover Sport.
May 2024: After watching this, be sure to watch my update video posted 14 months later: kzbin.info/www/bejne/qJalaKKCqdlkbNk
Compatibility: Similar procedure should apply to all L494 Range Rovers (2013 to 2022), and is likely very similar to most modern-day Land Rover models.
Tools Needed: Ratchet with 15mm socket and needle nose pliers.
Robb’s DIY Rating on 1 (easy) to 5 (hardest) Scale: Definitely a 1. Hardest part was just tracking down the leak.

Duuuude! I may not have had the exact same leak as you, but I took the advice and invested in a nifty endoscope. Found the leak in 5 mins of investigation. Just wanted to say thanks :)

[@robbsgarage]

Great! Where did you find your leak?

[@simonelrick6265]

@@robbsgarage I have the 3.0V6 Diesel and it's similar to the other engines with the leaking plastic coolant housing and pipe that sits under the intake manifold.

What a top bloke saved me a fortune thanks for doing the video😊

[@robbsgarage]

Brilliant! Glad to hear it.

[@ChrisHerndon-im1tl]

Love it! Just looked and that is exactly what was going on with my RR Sport! Thank YOU!

[@robbsgarage]

Fantastic! Glad it helped. I have 3 more RR Sport videos in the making (maintenance-related). Stay tuned!

i have the exact same car 2016 sport v8 and the exact same problem occurred you’re a life saver !❤️❤️

[@robbsgarage]

Sorry to hear of your issue, but glad you were able to resolve it! I just love this V8 engine. Hope to keep both of ours running well for many miles to come.

I have one I'm tracking down on my 2011 LR4 but like you said! Great trucks 230k on my and still running like a tank:)

[@robbsgarage]

Thankssss! Love getting comments from people in other countries.

Și eu am pățit la fel. Am schimbat inelul O ring și am rezolvat problema singur. Desigur am salvat ceva bani și timp. Felicitări pentru acest video. PS: Din păcate la acel moment nu exista acest video, când m-am confruntat și eu cu aceeași problemă! 😂

[@robbsgarage]

Well done!

[@BeckyStoltenberg-he2nh]

You are amazing. I am having the same issues with my 2016. Gonna see if this fixes my issue as well. Thank you so much.

[@robbsgarage]

Did you identify the leak?

[@dwboston1]

Coolant crossover pipe is the common source of coolant leaks on these engines. It's a plastic part that fails at a seam/join - it was updated for 2017 model year. It will destroy the engine if not caught in time. It's a POS to replace as the supercharger needs to come out. I'd check it just to be safe.

[@robbsgarage]

Thanks for the tip. This leak appears to be fixed, but good to know about the crossover pipe so I can plan accordingly. I’ve replaced that pipe on other vehicles and no matter what the engine it always seems to be a PITA. Every manufacturer these days insists on using cheap plastic that will crack/melt/degrade from the engine heat. Do you know how Land Rover changed it in 2017-aluminum, or different design?

[@dwboston1]

@@robbsgarage The updated LR part is still plastic, but it's a single cast piece instead of two pieces bonded together.

[@dwboston1]

There is at least one aftermarket part that is made out of metal.

[@Land_Raver]

Check for the aluminum crossover pipes instead of the plastic ones if you replace them.

[@robbsgarage]

[@ericpelka1757]

Great detailed quick video. Unfortunately I blew the plastic parts under our velar. 2500, they warmed head. I love the brand. Worked at corporate for the early SVR and LR4 designs. All have been great this one a lemon. Or just over heated to far. Temp gauges. Loose your coolant it reads good to wife.. 🤷‍♂️

[@robbsgarage]

Sorry to hear your experience. I love the brand too, so it’s unfortunate.

[@ericpelka1757]

After extensive repairs, swapping the to aluminum coolant pipes under the super charger. New water pump. Even used block seal to fix head gasket. But Kept loosing coolant. I’m not one to dump it on the next guy. They say only 8 thousand’s of machinable surface. Between block and heads. I saw the stellar reviews at Rover parts depot. And his engine work. Opted for a new engine. Only 38k miles. Don’t let your wife accidentally overheat these new models. You must turn off the car immediately. I’ll keep you updated. Great channel clean work/ videos.

[@amandameyer9543]

My Range Rover is just like this one but a 2015 and it has a coolant leak. I will check where this video did. Hopefully I can figure it out.

[@robbsgarage]

I hope so too. Please comment if you have questions or need any guidance and we’ll see what we can do.

[@jooeee23]

Great work 👏 👍

[@robbsgarage]

Thank you, and thanks for watching!

[@Jean-Mi_Paradis]

Very informative video!!! Thank you very much. Quick question which is not related to the leak. Looks like you have 20 inches rims. Could you please tell me more about the tires mounted on them? I like very much their style. Many thanks in advance!

[@robbsgarage]

Correct, 20’ TSW wheels mounted on 265/50 Nitto Ridge Grappler tires. They provide a nice aggressive look and maximize the wheel well perfectly, plus they handle great off road and yet aren’t noisy on the street. Highly recommended!

[@Jean-Mi_Paradis]

@@robbsgarage Thank you very much for the response. All the best

[@m.w.8336]

There is supposed to be a clip on that hose that will prevent it from coming out.

[@robbsgarage]

Thanks! I will have to install a new one then. Must have come off.

[@LpizzMarzee]

You didn't actually show me how you disconnected the hose 😅to put the o ring on 😑

[@Moonstone-vi4ru]

That same hose is marketed by Land Rover of Denver for $120😮

[@robbsgarage]

Ouch!

[@firescrap]

Hi Robb. Found your link chasing a coolant leak. Wish mine was as simple as your repair, but it’s the dreaded cross over pipe. Anyhow, you mentioned that you experienced a “noisy tapping” sound. Can you please tell me more about that? Thank you

[@robbsgarage]

Good luck with the crossover pipe replacement. I dread the day I have to replace mine. Whereabout in the video did I mention a noisy tapping? Been so long I can’t recall but maybe if you mention the section it will jog my memory.

[@firescrap]

@@robbsgarage thx for the reply. In the opening you mention you only had 2 issues with your RR. One issue was a tapping or knocking…..

[@robbsgarage]

@@firescrap oh, right. I thought you were referring to a tapping sound with this coolant leak. At about 45K miles the engine started to produce a tapping sound. Turns out one of the tappets/lifters wasn’t right. Thankfully it was still under warranty and the stealership replaced not only all lifters on that bank but also the timing chains, tension rails & guides, tensioners, and related gaskets.

[@firescrap]

@@robbsgarage That’s what I figured. Do you mind if I pick your brain a little more on that?

[@robbsgarage]

@@firescrap sure!

great advice thank you keep the good work

[@midnightrun1256]

What do you do if the temperature gauge is fluctuating a little bit taking a long time to get hot no coolant inside the overflow coolant tank. Also no heat coming out of the car bare minimum and the blower motor seem to push out the heat faster rapidly coolant topped off.

[@glambeauty199]

I was quoted $12,000 for this fix… where are you located so I can ship my car to you.

[@robbsgarage]

Had to be a different issue if they wanted to charge you $12k. A dealer might charge $3-500 to diagnose and repair this particular issue.

[@longcashdj3381]

If you don’t mind me asking how do you get the piece off to put the O ring inside?

[@robbsgarage]

I just pulled it straight out. Will need to use a pick tool or flat blade screwdriver to remove the o-ring, then I recommend using some coolant to lubricate when pushing the pipe back in with the new o-ring on. The #6 o-ring held up for 14k miles but I then developed a new leak. Will upload a new video this weekend with a different size o-ring (metric) that’s held up for 6K miles with no issues yet. Will post more updates as the miles progress.

[@longcashdj3381]

@@robbsgarage this video was very helpful I was headed to the shop until I seen this video I actually found the broke o ring sitting on top of the fan already I have to replace the whole part everything was melted

[@longcashdj3381]

@@robbsgaragedo you know why mines could still be leaking after replacing the whole piece?

[@robbsgarage]

@@longcashdj3381 if it’s a brand new pipe from the dealer then the only thing I can think of is either it’s not pushed far enough into the radiator or the radiator inlet was damaged. Did you put some coolant on the pipe as lubricant to push it all the way in?

[@joshuaray5065]

I have a leak on the same pipe, but pipes actually broken on mine so will have to replace. Any chance someone has the part number?

[@robbsgarage]

I’ve been searching the repair manual and realOEM.com but can’t seem to find it. A dealership can probably locate it quickly for you.

[@joshuaray5065]

Just wanted to let you know I found it. LR 146301.

[@robbsgarage]

@@joshuaray5065 nice. How much? Do you also have the 5.0L V8? I may research to see if this is universal with the V6 motors.

[@BenTumbling-ld2ku]

with all the tools you used it is not a 79 cents fix, the "o" ring part is just part of the total cost. it is cheaper than the dealership but it is not a 79 cents fix.

[@robbsgarage]

The tools used in this video helped track down the leak, but the actual repair requires no tools at all. Now that I’ve done the research, anyone watching this who sees a leak at this location can repair it without any tools. 😊

[@x3cpgaming595]

How you remove? Squeeze clamp??

[@robbsgarage]

On my vehicle, I just pulled it off and then pushed it back on by hand after installing the new o-ring. I wouldn’t advise removing it unless you see a confirmed leak, because the existing o-ring will have expanded and, as a result, once you remove the pipe you will likely need to install a new o-ring regardless if the existing one is broke or not.

[@x3cpgaming595]

@@robbsgarage thank you so much

[@eastcoastoutdoorz6940]

Get a pressure tester!

[@robbsgarage]

Oddly enough, I tried and could not locate the leak with my pressure tester. That was the first thing I did, then when I couldn’t find the leak I decided to record the rest of my steps in case I could post and see if anyone else had ideas. After I found the leak is when I decided to make this video to show everyone else the random culprit. Have you ever used a pressure tester and not found the source of the leak? First time for me. Maybe it was because I hadn’t removed the covers yet…

[@eastcoastoutdoorz6940]

The covers are always annoying most of the times when I can’t find a leak with my tester the leak is internal at that point I have my barascope in the spark plug cylinder searching for the coolant on the piston head, rovers leaks a lot I work at the dealership they’re known for it lol

[@robbsgarage]

Thanks for the advice!
