Repair Range Rover Sport Coolant Leak 

Great! Where did you find your leak?

@@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.

Brilliant! Glad to hear it.

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

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.

@@robbsgarage yeah same mine has 125000 miles been very reliable so far

Thankssss! Love getting comments from people in other countries.

Thank you, and thanks for watching!

Well done!

Thanks for watching!

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?

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

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

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

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

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

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.

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!

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

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

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.

@@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

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

@@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?

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.

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

@@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.

Ouch!

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.

@@robbsgarage thank you so much

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.

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. 😊

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…

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

Thanks for the advice!

So frustrating. Have you identified where the leak is coming from?
