had warranty pump replaced 1.5 yrs ago....no leaks,,,check every month or so...all is good, i still peek under car before driving :}

 

So I can take my 2017 C4S to the dealership here in Dallas when it starts to leak and they will honor a 10 year water pump warranty even though the car is out of warranty?

6k miles no leak yet

 

Yup, just like kalathr said.

 

Thanks- I plan to be a contributing member after this great news!

 

Great to know!!

 

2017 C2S 32k miles, found water pump leak during pre-delivery inspection (just sold my car, which is a great car and I'll miss it dearly). All work being performed under warranty. Got lucky with timing since warranty expires next month. During work, due to corrosion, a bolt broke between a heat shield and the left turbocharger oil tank. They also replaced the turbocharger oil tank. I don't even want to know how much this would cost if it wasn't covered under warranty.

 

that cooler you speak of is $544 plus labor in IL… one expensive bolt!!

ask me how I know 🤣

 

My 2018 c4s had the water pump leak at 7k. Now the tensioner locked up and melted the serpentine belt. I think its bad work from the shop on the water pump. A tensioner should last more than 8k miles. I will fight them if they try to make me pay for it. Oh and btw my parst are coming from Germany so its been two weeks in the shop and counting

 

Wonder if a tune would impact warranty.

 

Could be...

 

Depends on what breaks and which dealer.
There is no relationship between these water pump failures and tunes.

 

My 2018 water pump failed at 43k miles. I saw some pink fluid on the garage floor and didn't even have to look under the car to know where it was coming from. Drove it to the dealer, got it replaced for free. Since they have to remove the belt to do the work, I handed them a new serpentine belt to put on instead of reusing the old one.

It was time for the serpentine belt since I got my 2018 in July 2017. All totally free except my cost for the belt from Suncoast. ~$69.

 

tensioner damper is known failure item, they go bad just sitting there, I guess the seals go bad and start leaking fluid. Easy to diagnose if you pop your head under the car every once in a while you can keep an eye on it. Here’s the one I removed from my car, and the replacement for comparison:



If you see a bunch of grime on it, it’s because the oil is leaking out and collecting dust to make the grime. Replace if it looks like this! They are $30 parts, but takes effort to get there, have to remove everything same as belt/filter, and then you can remove the tensioner assembly and replace the damper (or the whole assembly is about $250 if you want to go that route).

 

2017 GTS 33,000 miles no issues and recently inspected.

 

i have a Cobb stage 1just took off my 17 I just sold, its in the for sale parts.
