If you work for a dealer or GM, you really need to remove the links from your post. Does not take but a little primitive URL hacking to get to where the public was not meant to go.

well it's too late to edit them now

I did get a letter concerning the radiator and I can't find it right now. So I did a search of recalls on "my GM" and no additional recall showed up.

Is this a recall or just an extension of warantee coverage covering this defect?

[Bobber]

Just got the letter this past week as well... It's a TSB, not a Recall.

 

But, my dealer had already replaced my radiator and t-stat an oil change ago. Apparently it was known about at that time and they had found my radiator to be leaking. (I had just completed a 650 mile trip the day before and the burp bottle was empty).

Thank you for the confirmation... I have been avoiding the dealer trying to ward off the hack job, LOL.

 

Glad your issue was covered.

So.......I guess that's why I keep detecting the smell of coolant from behind the grill and the occasional low level in the overflow tank........marvelous.

[gmcleer]

I dropped off my truck for repair of the rusted frame and mentioned the letter regarding the thermostat.

 

Picking up the truck today, frame is done. They also said they pressure tested the system and no leaks, so they aren't going to do anything else. I guess I'll keep an eye on it for now. Its a lease and I still haven't made up my mind if I should buy it or move on.

[joshc64311]

I had this done, now truck seems to be running hotter. Does anyone know if the new thermostat is a higher temp?

[ron 513]

just an FYI. not all 2014 trucks are included.

 

my 2014 gmc 1500 with 37500 miles has the smell also. Was at the dealer 1/26/17. Was told radiator is the issue. 1200.00 repair to replace radiator and thermostat, coolant ect.

long story short mine was assembled in mexico and is not included in a tsb. or special coverage for radiator leak. REALLY!!!

Yes you are reading that correctly. A new thermostat will be installed as to eliminate the cycling that is causing the problem.

Can you please explain, how a new thermostat will eliminate the cycling. Or stop the radiator from leaking in the future.

 

Is the new radiator to be installed an updated version or same?

 

Isn't that the job of a thermostat; to cycle the coolant through the radiator depending on temperature?

 

I guess what I'm asking is, how is the new thermostat any different?

 

Would a lower temp thermostat be better?

 

I was considering getting a lower t-stat; just always thought the truck running at 210° was high in my opinion.

I was answering his question based on the TSB. It can be found in post #17 above word for word what they are supposed to do in the situation in question. I see you have a 2015 model and the TSB above only applies to the early model 14s. Maybe there is a new one that covers older models. You would have to check with the dealer on that unless someone here knows. Apparently the opening and closing of the defective thermostats was putting pressure on the radiator and causing leaks.

[355HP Z71]

I am a little confused . In TSB # 15829 It says it covers 2014 models and in the other TSB #PI1513A it says the 2014 are not covered ?

Before I traded my truck in my 2014 radiator was replaced under that TSB. my truck was built in Mexico

This is the answer I got from gmc customer service. Truly Ridiculous.
