One month old see small amount of coolant 10-15 cc on garage floor notice a leak. Service sends radiator to shop BAD core needs new radiator. Next week will be 5-7 days ? General motors has the finest part suppliers !

What are your last 4 VIN numbers? It would be interesting to track issues like this to see if it might be one of the reasons for the 4-6 week "QC" delays for the first batches of cars.

Regardless, that's why there's a warranty. Should be good as new in no time.

Service department at Classic Chevrolet in Grapevine Texas did an excellent job. Called me today at 1200 and said car was ready. They overnighted the new radiator from Lansing Mich. Marsha in service was great. In and out 2.5 days.

Beginning yesterday, I can detect the slight smell of coolant. Nothing is pooling and there is no evidence of a leak, but I smell what I smell. Time for a trip back to the service department?

What say you?

Is the overflow filled up such that is the hotter weather you could be blowing a little out (because it was slightly overfilled when the radiator was replaced) and then is dry by the time you get home and check?

Thanks! Good thinking. I will check that out. I know it's not coming from the car in front of me. It gets worse when I pull into my garage and I can smell it coming through the AC vents.

Where you able to see coolant leaking on the garage floor or get just the smell? What were the symptoms?

Hmm, it may not be the radiator - it might be the heater core.

Still, it's more likely to be the radiator, given that there have been known issues with the radiator.

Thanks Mobius! Should I ground the car until service?

If the odor is as obvious as you say, you may consider it.

Have you been checking the coolant level in the overflow tank since you noticed the odor? If it is low, at or below the "low" level, that's another indication of the leak rate.

PS. I had a heater core leak in my 91, and coolant dripped from the core onto the radio receiver, damaging it.

 

[Raydor]

Thanks for the reply!

The fluid level in the overflow tank is topped off. That was the first thing I checked when I pulled into the garage last night and the odor got stronger through the vents, so I searched the forums, found this thread, and realized my VIN was right in line with others who had the problem.

I first noticed the smell yesterday after driving through pounding rain and a little standing water then, it got worse last night, prompting me to check the level. No apparent loss so far and the smell is receding, now giving way to the burnt oil smell left-over from my oil change 2000 miles ago, but that is another story.... Stupid service department.

Right now, taking it for a drive in the fresh, night air. Hoping to catch a clue. Apparently, I am clueless, that is, if my ex-girlfriends are anyone to be listening to.

Thanks again, Möbius. You rock!

So when I picked up my Vette today, I got to the dealership about 45 minutes before my salesman arrived. I went back to the service area and crawled all over my car. I also had the chance to talk to the Vette mechanics, and I asked the a number of question about my car. One of them mentioned that they have only had one C7 in for warranty work.

The problem with that car was a pinhole leak in a seam weld on the heater core. I thought it was a hell of a coincidence and that you'd find it interesting.

Wow! That is definitely interesting. If the hole were small enough, it could cause the exact symptoms I am having without showing a noticeable loss - and I'm sure you were thinking the same when you posted this. Thanks again and good looking-out! I will notify my Stingray Guy next time I see him.

What is the previous digit in the VIN? I am guessing 1, but it could be a 0 or a 2. It will tell us more about when your car was built.
