Radiator Leaks 1500 miles

Jims-c7 · Mar 19, 2014

Radiator is leaking. Service has ordered a replacement. I noticed anti freeze spots under left front of car. Service tech says its a bad core.

Yours is the fourth report of a bad radiator I've seen. We have had at least one other member on site that had the same issue. I wonder if GM has received a batch of bad radiators from its supplier?

A friend here in STL has his leaking as well. He has a new convertible. Less than 1000 miles.

Just had my radiator replaced this morning. A leak was noticed by a service tech while doing a oil change. It came off the build line Oct 7.

Which dealership did you use, Raiderh20boy? Did you go to Rio Vista or somewhere else?

I just talked with my friend that has a new conv. and he has a transmission coolant line and fitting being replaced that connected to the radiator that was leaking. What the deal with these leaks? I am sure there are others out there that have not noticed the problem. I am going to my dealers tomorrow to be sure it's the radiator and not the transmission coolant lines. Leak seems to be in the same location....putting in my radiator tomorrow;-(

Sorry Rodney for taking so long. Yes, Abel Chev in Rio Vista is now and future service center for ALL OUR CARS.

Jim; While your there for this replacement ask if there is any kind of a TSB for this issue yet. It appears that there is an increasing number of owners reporting this problem. I suspect as spring weather arrives there will be even more reports of this problem reported.

Noticed some fluid in my driveway as I closed the garage door today, seemed like two streams, thought it might be the AC unit giving off accumulated ice.
I'll look closer tonight as I leave for an appointment.

Thanks for the heads up

Guys: Please check and see if there is a TSB or PI for this problem when you take your car in for replacement radiator. The number of owners reporting this problem is growing at an alarming rate, and I feel like GM has to know there is a problem by now.

Which fluid is leaking out of the radiator. is it automatic transmission fluid or coolant thanks

It appears to be the coolant strictly by color and it matches the Same color fluid as that in the tank closest to the passengers side firewall
