Bump - what's the latest F355bob?

 

the leak seemed to stop. The pipe under the pump had streaks of dried antifreeze just like before my first pump change. I cleaned it all off and no residue for the last 400 mi. so dealer said cant do anything without evidence of leak. Still have 2 years on warranty and I check it after every drive.

 

Just had a water pump replaced on 2018 GTS

 

Isn't anyone thinking more like class action lawsuit. If this goes out while you are driving your engine overheats and shuts down immediately?

 

I just took my 2017 GTS in for its 2nd replacement pump in 15,500 miles! I asked the dealer to try to find one that could last more than 6 thousand miles this time. Good grief.

 

I'm sorry to hear about this X51 and wish you Good Luck!

It would help this Forum if you could post the part numbers of the replacement Water Pump you received and will receive.

Cheers,
Chris

 

Sorry to hear this. When was your car built?

 

Water pumps are designed to not catastrophically fail right away. They develop tell tale leaks and make a tell tale grinding sound and can continue to function properly for many many many miles.

 

Didn't read the entire thread, but my water pump was replaced in early July after it failed during a track day.

My car is a 2017 Carrera 4S, mileage was just shy of 46k km (29k miles) when the failure happened. I was aware of this possible problem and I'm glad I got to have it fixed under warranty.

That's exactly what happened to me. I noticed a leak at the end of a session, which is unusual even in the case of a coolant tank overflow. Drove the car back home and to a few places for the next few days without any issue, and then the temperature peaked to the roof. I parked the car, got it to the dealership on a flatbed and it got fixed in time for my next track day, which went flawless.

 

Anyone know how much a water pump replacement actually costs?

 

Dealer or independent shop? DIY is also pretty easy.

 

Whatever detail you have...

 

My best estimates:

Dealer, OEM pump + labor = $1200

Indy, aftermarket pump (if available) + labor = $600, OEM pump + labor = $900

DIY, 2-3 hours labor

 

when a water pump fails is it the impeller that goes bad or maybe disintegrates

 

It starts when impeller shaft bearing seal fails. Coolant then works its way into the bearings, dissolves the grease and weeps out the bearing vent hole. The pump at this level of failure will continue to function somewhat normally for quite a while. Over time the bearings start to break down and fail making a rattling noise. Then the shaft begins to wobble in the housing and the impeller will start to break up, that is catastrophic failure.
