I had mine done about a month ago. New radiator thermostat and housing. Dealer had no clue about service bulletin. They called me and said they found bulletin and did what I told them. (Thanks to this site)

Not that it seems like this is a real,hot topic right now but I just got my truck back. They found the leak and replaced the radiator. The bulletin is PI1513 and for the non max tow 5.3 the updated pa

Here is a link to a possible wide spread issue.   http://oemdtc.com/25613/coolant-smell-andor-slight-leak-at-radiator-2014-2015-cadillac-chevrolet-gmc-vehicles     Also I checked the part numbers

Hi there, first time post here. I just picked up my 14 in 12/17 and have noticed since I got it the coolant is down about an inch in the resovoir and my driver side is cracked. Just dropped it off at

My truck had the same issue and had replaced the radiator and it was still leaking, now they want $300 to finally fix a leaking radiator heater hose since it's not covered under the extended warranty.

 

AC compressor gone as well, so make sure you get these items fixed or replaced before your warranty runs out. These two items alone WILL eventually fail and I think the radiator and labor is over $2k.

 

AC compressor is covered under the warranty but I will have to wait 2-3 weeks for a "redesigned" part to arrive. This truck is gone the minute I get it back. I have to cut my losses before it really start to hurt. I hope the trans doesn't fail me before I sell this POS.

 

Sorry for venting...just so tired of all the issues

 

Sell your truck while your truck still has some value left in it.

Same issue as the rest, just bought my 2015 silverado into the shop yesterday for low coolant, smell of coolant coming from the front. They just called me and its out of warranty. Truck is at 45,100 miles. They want to charge me $975 for just the new radiator with labor and tax not included yet.

 

Edit: my dealer is telling me pretty much that im a liar and making things up on this TSB and that there is no such thing for this truck.

 

Edit #2: spoke to the manager and told him what happen ans the run down of the issue, he called me back 15mins after hanging up and found the tsb and said its 110% under the powertrain warranty and thermostat and radiator are being replaced

$8000.00 trade in allowance from GM, 1500.00 private offer, 3000.00 old age unit cash (dealers could use it on any vehicle they chose) and $1250.00 bonus cash from my GM credit card made it hard not to go with another Chevy. I had my doubts, but no way I was going to get this kind of deal with another brand.

Local GM dealer has been good to me, so long as they recognize the problems and repair it for free, i'm good. We have a fleet of over a hundred diesel Fords (and hundreds non diesel) where I work. lots of down time to repair..over and over again. They are the cheaper truck to buy for a fleet, but cost more in the long run. Dealer cannot fix the 6.7 properly and they usually blow up again, took them three tries to fix one F450, they're too complex and the old experienced techs have retired. We are now trying out the Ram 5500 cummins. Unfortunately GM doesn't sell a truck that suits our needs. I can get an amazing deal on an F150 (fleet pricing)... I still wont do it.

 

Sorry a little off topic. Fix my radiator GM, keep me happy. hopefully the problems taper off. I do like the truck.

You could try showing your dealer this letter about the defective radiator.

I get that this is a little old.  I'm way out of my warranty on my 15 Yukon Denali.  Is there a good aftermarket radiator or do I just go with the ACD?  This 15 Yukon has been the most costly car I've ever driven in my life!

Aside from the bad '14- Late '15 GM truck and full size Suv Radiators, prepare to replace your A/C Condenser as well. :(

They are also defective in the same models

This will definitely be my last GM.  I get that all cars have issues. I've just never had a vehicle with so many so quick and no help or willingness from the manufacturer. 

 

I was hoping to find an all aluminum radiator.

I did give then a call. It does fit. When they previously had it listed, it was not listed for a Tahoe/Yukon/suburban/Escalade.

Did some searching and have not found much feedback on the Mishimoto radiator.

I did DM someone who installed one, no reply.

Any other members who have installed it?
Any feedback?

Install seems pretty straight forward with no need for front end dissassembly

      ‘25 Silverado purchase- back to dealership for bumper/radio issue

      By Atomicgrl · Posted

      The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps

      Make sure the latch mechanism is properly greased. Look at the catch for fresh marks/scratches. And see if it has moved a little, too.

      Thoughts on these wheels?

      By PBNB · Posted

      I have the 18" black mutilspoke wheels that came with my truck. I like them as they are very subdued and look good with the 295/70's    I am sure that the next set of wheels I get will be some after market all black wheels. Or maybe some AT4X wheels.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Interesting question which you partly answered in the word 'potentially'. I think that is going to be a 'point of reference' inquiry. What are the touchstones?    This will sound petty but it is the main source of end fighting in threads on this topic. Define a motors "Life". Think about the various arguments that have been entertained on these pages in that very argument.    I can only speak from my viewpoint. Engine "Life" in my world is defined by power cylinder integrity. For the majority of engines it is the bore/ring interface that quits first. Loss of seal. Oil consumption and loss of power. Most Pro motor builders would agree and there is a good deal of information on using "Leak Down" as a primary indicator of bore integrity. At home a compression test is more the thing. If we can agree on that then I think CC Jensen has done its homework and I'd find it valid.    Now by my own definition, Dizzy, wife's Ecotec 2.4 I-4 has been dead since about 80K miles. And yet we have logged over 200K miles more on it. "Life" and "Usefulness" are therefore independent.      I know a mature fella right now who has just hit 300K on a Mitsubishi 3A92 NA MPFI motor and has done compression test every 100K. It was 205 psi after break in and is now about 195 and still even. He uses shelf oil but good filters and adheres to a 3K mile OCI. He even do UOA's on each of them for the first 50K.      I also know a fleet mechanic with that same motor that gets 300 to 500 K out of them but the are oil using, wristpin sloppy, skirt slapping motors. He ran one with a piston pin so loose the piston was bouncing off the cylinder head for about 20K miles before he called TOD. Both of them claim success.
