Antifreeze Smell Thread

If so on the soft plug then there new old stock will be the same. Do we know where the pumps are made and why for this soft plug.

We don't know where the water pumps are made. The question has been asked here before. Until someone can look at the box they come in and tell the world, it will likely be a long time before anyone knows. XtremeRevolution has posted that the water pump problem is known to Chevy and they have taken measures to fix the problem. That having been said, there is no notice of that in GM's Techlink, so wait and see. The overflow reservoir venting near the cabin air intake is a completely different goose. I am still convinced it's a tie in between the electronically controlled thermostat and the pressure that builds up in the overflow tank. I'd be delighted if someone could prove me wrong and show the real reason for the smell. "Ooo Ooo that smell. The smell that surrounds you".

Yes. The new pumps are identical to the old ones. We stock one, ill check the box tomorrow to see where its from.

Well I got told they pressure tested it and found no leaks, coolant level is fine. They claimed there was no bulletin or anything out regarding this issue. I mentioned PI 0740 and he's like "oh well, we'll go ahead and check this one out..... The service adviser claimed his tech was on the phone with GM tech support. I find it sad that we need to tell these guys were to look to fix a potential issue.

I am starting to get the smell intermittently. At times it can come on so suddenly and strongly that it is instantly nauseating. Film on the windshield, and res. level is about 1.5" lower than it was at my last oil change 3K miles ago....either that or i didn't notice that it was already starting to lose coolant.

Car is 9 months and 14K miles old. Having toxic coolant leaking into the passenger compartment/coming through the vents is not at all OK.

I'm tempted to try to find it myself, but if i do then i'd still have to bring it into the dealer for the warranty work or i assume i'd have to pay out of pocket for whatever part(s) are needed... and that's not going to happen on a new car.

We found it, GM just won t fix it.

Have the interior issues (smell/film) also been traced backed to the water pump bolts/soft seal?

Not on mine and many I see here. There are no leaks in many if not most of these complaints. Also anyone who has posted a leak as the cause has only seen the smell re appear. I don t think those small leaks are the main issue. A small drip from the bolts on the water pump would not give the consistant strong odor I have. If that s the main cause why do so many have the smell and no leak, IMO, because it s the vent on the tank. They have put the dye in mine too and found nothing leaking.

Dealership called and said they are replacing the heater core... I hope to **** this works! it will be in next week.

I thought you said you had no leaks??? Why replace the core?? I don t want to jinx you but sounds like a fishing expedition to me. Someone else post here about a heater core change that did not solve the issue...

So then we haven't found it.

I don't see how the smell could be generated from a slow steady leak. I go days without smelling anything, and then all of a sudden get a smell so strong I have to put the window down in <30* weather or i'll be sick.

I've had several vehicles with a slow leak from the "weep hole" on the water pump and didn't notice for some time.
