Now this is a new twist to the water pump problems. There mounting bolts may be leaking.

Notice how the "seal" is not included with the pump = DUMB!

That's DUMB because when a new pump is installed, a new seal is always required!

so what if its not included with it. maybe they use a different manufacturer for it. all that matters is that the bulletin says use a new one and here's the part number. there is no need for calling anything dumb...

...except when it takes two weeks to get Warranty repair of a leaking thermostat housing because the local stealership doesn't KNOW that the seal ISN'T included, thus making a one-day job into a 13 day job!

...and, that's after GM is aware of the problem and yet has NOT stocked the necessary parts needed!

I wonder if the coolant leak is so little they can't find it. I had my car do the dye test and they cannot find a leak but say they do notice a smell and my coolant level keeps dropping.

Been a long while since I have been on this board.
I have owned my Cruze since October 2010, have over 42K miles on it, and now am troubled by a coolant leak.
The dealer told me today that it was about a gallon low and I topped it off about a month ago. They went over everything and could not find a leak. They are also aware of this bulletin.
For those that have had a low-coolant level leak fixed, what was the smoking gun? What did they finally catch?

 

[70AARCUDA]

...there are two types of "leaks": (1) external leaks where you are physically to see the escaping coolant and (2) internal leaks where the coolant escapes someplace it wasn't intended to go, such as leaks inside the turbo or engine itself, which cannot be seen, only diagnosed by competent investigation.

I'm moving this up to a sticky as more reports are coming in. If this becomes a TSB and someone can get that TSB number, please post it

I'm currently in touch with Tom Read regarding these water pump issues.

I found this PI0762B posted by 70AARCUDA on cruzeforumz.

PI0762B.........Coolant Leak at Water Pump; replace water
pump & gasket, replace engine mount bolts. (it was posted as PI0726B but I think that is a typo) Technical Service Bulletins (TSB) & Safety Recalls - Chevy Cruze Forum - Chevrolet Cruze

Cruze — Coolant leak at water pump

Replace the water pump and gasket. Replace the engine mount bolts.

Replace the water pump bolts. The gasket will fix the leak at the water pump bolts.

PI0762B

The initial PI0762A was saying: A Coolant Leak at Water Pump/bolts (11-Jul-2012); replace water pump, gasketand thermostat.

Why would the new PI ask for replacing engine mount bolts? How does this relate to coolant smell?

Yes, it WAS a typo, but it's been corrected now. It is the newest information available; found on page 9 in the November 2012 issue of GM TechLink:

http://sandyblogs.com/techlink/wp-content/uploads/2012/11/November-Techlink-2012.pdf

...bolts could be (a) wrong thread, (b) accidently penetrating into water jacket (bad!), or (c) needing "locking" against vibration-induced backing out, etc.

[Ragin Cajun]

MIne is going back to the dealer Monday for what I expect to be the water pump. Cant believe these issues at 22k miles.

 

[XtremeRevolution]

With regard to the water pump failures we've had reported, I'd like to touch base with everyone here and provide some information. I've been in direct contact with GM over the past week regarding this issue and believe the information I've learned could be of some use.

If you have any issue related to a loss of coolant, loss of heat, or rising engine temperatures and believe that you may have a leaking water pump, the best way to get it resolved is to contact Stacy directly and have her coordinate a visit to your local dealership. If you are not having any issues with your Cruze, there is no need for concern. While I cannot get into specifics regarding my conversations with GM, I can assure you that GM is standing behind the Cruze and has this issue under control. Should you have any questions, send Stacy a private message.
