Thanks guys. Fireaxxe for sharing the tsb with the attached image helping me find the leak on the passengers side of the rad. I am just about up on warranty so this is great.

 

I had noticed a couple drops of red fluid on the ground a couple weeks ago and took it into the dealership. They didn't find anything and charged me $65 for looking at it. I asked her if I found the leak, would I be reimbursed. She said yes, so I'm going to make sure.

 

Today, I smelled rad fluid when walking around the front of the truck. I then researched when I got home and low and behold this handy thread. Stoked! Sucks how many times I've had to bring my truck into the dealership to get things fixed, but I really love my truck. Nicest truck I've ever been in for sure, and I work in the oil patch so see new trucks all the time.

 

I have a broken tab on my drivers side as well.

 

Thanks again. This forum rocks! (Am very happy right now)

Took mine in to look at several things including the clamps that hold the radiator together. They said pressure test was fine and found no broke clamps(concern not duplicated at this time).They must have looked at the hose clamps! Just wanted it docemented on paper at this visit.

I had the same issue with coolant smell from the front of my 2014 and could not find a leak. I just dropped my truck off at the dealer .They can't find the exact spot of the leak, but found fluid laying in the front bumper. They are replacing the radiator and thermostat.

I have about 20,000 miles on my '14 and I too noticed this weekend that my coolant level was below the cold fill line. Also, checked that clamps and the driver's side was cracked. Is this enough for GM to replace? Does anyone have the text from PI1513 that was mentioned? Scheduled the appointment to have it looked at this Thursday, hopefully the "qualified GM tech" will be able to locate an issue and repair it. I'm guessing it'll be in at least once more time for a repair if needed.

There is a TSB on radiator leaks. Has something to do with the thermostat cycling too much and causing stress fractures in the rad.

 

I just had my radiator and thermostat replaced under warranty. 35k miles on my Sierra.

Just got called back from the dealer. Coolant levels are fine, truck was only there an hour. I'm sure they just filled it up. Guess i'll keep an eye on it.

ejdziurka, the coolant level in my 2014 is at almost the exact same spot. one thing that I have noticed is the level in the overflow tank never moves, whether the truck is hot or cold. you can squeeze the top radiator hose when it is cold and make the coolant move in the tank, but when the engine is hot, the hose is very solid, no give at all.

Don't have the text for the tsb but just heard back from my dealer. Radiator and thermostat are both being replaced under powertrain warranty. i just mentioned the tsb and they looked it up.

2014 SLE double cab V6, I notice my coolant was low in the header tank, since I'm beyond the bumper to bumper warranty, I went to the dealership to grab a jug of coolant to top it up. The parts dept steered me to the service department who informed me that the V6 trucks are now included in the extended warranty. they were very helpful and it took about 10 min of searching to find the leak (top corner of rad passenger side front). I didn't really notice anything other than the odd puff of steam in the winter time. I thought it was snow stuck in the radiator. If your coolant header tank level is low, there's a very good chance that the rad is leaking. Another clue for me was I noticed the coolant temperature gauge had been reading hotter than usual.

 

Cheers.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
