I have 150k miles on my LR4. Bought it with 90k miles. I put 60k on it in just under two years. My rear crossover just started leaking a lot after a long road trip. Used a quart of coolant after 900 miles of driving. Confirmed with a u/v light a nice pool of coolant near the firewall.

Been looking at whether to get OE or aftermarket pipes. I don't want to do this job again soon. I know with OE I'll get another 100k plus. But I'd like to hopefully get something that last longer.

 

No one wants to do the job “again”, but I’m afraid you’ll just have to get over it… coolant hosing is a maintenance item. As are many of the fluid and filter changes many often overlook.

at the end of the day, you got good service out of the original . Many dump their vehicles when the pending maintenance costs are on the horizon. Which makes them quite affordable for purchase.

At the end of the day, the oem solution will last another…

 

I'm a big believer in genuine manufacturer parts. They often make improvements over the years too, so you get better than what you had. Having said that I'd also be interested to see if there's a better option that can prevent catastrophic failure. A cast aluminium replacement instead of plastic may just make the gaskets the weak point (?)

 

@Pwd3 If the cooling the system is good, those gaskets should not be the problem, hose clamps should be our only real issue, they simply get loose with age.

 

I recommend testing your thermostat as well. I just replaced mine at 160K miles after replacing my water pump twice in the past 10K miles not knowing my thermostat had gone bad. A bad thermostat will cause excess pressure on the top half of cooling system and will cause hoses to leak or crossovers to break. A Gates OEM thermostat is $56 on RockAuto, so it's not an expensive part if you've never replaced it.

 

I found these on Atlantic British. Anyone try these?

 

Interesting that I can’t seem to confirm they are for the 3.0 l sc engine. I see them confirmed for the 5 l.

from the picture they look suitable. Others have purchased knock offs from …., complained about the quality, then returned them.

 

My front cooling pipe failed a couple of weeks ago on the 2016. Also melted plastic into the radiator. $3000 USD to get it all replaced. I bought this vehicle knowing what I was getting myself into and truly do love it, I just wish I could get lucky for say a two-year stretch with just doing oil changes and tires.

Has anyone been lucky like that out here with one of these that's past 120k miles? I can keep fixing it up to a point with a chunk of money set aside but the thought does cross my mind to buy a few year old Disco Sport from Carmax and get it under their good warranty for dealer upkeep or just lease a new Tiguan and call it a day. We'll see how it goes for the rest of the year, anything else repair-wise this year of this magnitude would probably have me ready to unload it.

 

:-) I'm at 200,000 km. Sure, the engine is noisy... but not demanding a deeper repair at the moment. I am in the habit of frequently changing all fluids and filters.
I also use LR parts. The knock offs just don't measure up.

It is a very good vehicle and I drive it hard and in those places most wouldn't take their's. No problems. But keep up on the maintenance and repairs or the issues will multiply.

Truth is, you got to pay to play. And frankly, the Tiguan is a lower caliber vehicle. Yes, well built but not nearly as comfortable or capable. So, you have a choice.

 

Yes, I have 152k and after the timing chain, all is good. Remember, everything you read about will need to be maintained or replace. I have done front control arms, rear upper control arms, parking brake seized, front fan tensioner pullies replaced, brake/rotors etc. The car is durable but the the engineer who designed the tension arms with steel on aluminum should be assigned to designing sticker or Logos for the cars.
