I have an2015 gmc Denali HD with about 65k miles. I just noticed a bad smell while driving(almost like a WD40) When I parked I noticed a clear fluid leaking from what looks like the passenger side of the engine compartment. It is pretty clear fluid. I don’t think it’s coolant or fuel. No Lights or codes and everything seems to be running normal. I have an appointment on Monday but just wondering if anyone may have some thoughts and suggestions of things to look at before then.

brake fluid?  check the reservoir before going, and test the brakes several times that they are solid before driving, and if they seem sketchy or one side of the reservoir has emptied out totally, get it towed in...

 

If it's further back towards the firewall (and at all similar to older trucks), it could also be water dripping from an a/c drain hole (and would be completely normal).

Had an engine mount on my 2008 leak, they were filled with a "hydraulic" type fluid that looked like engine oil.

 

It makes quite a mess too, goes everywhere, so maybe some on the exhaust manifold?

I will be checking the brake fluid first thing in the morning. They felt fine when I was driving it but I will make sure it’s not them before I drive it again. Thanks for the thought. 
 

It’s leaked a lot of fluid and constantly so I don’t think it’s something smaller like a mount. I haven’t noticed it on the exhaust man at all. It looks like it’s running off the block from underneath. Can’t see the area from the top.   
thank you guys.

Have you done the "taste" test on the fluid?

 

Fire the truck up with the AC on full, and wait for a puddle to see if it matches what you have been seeing.

I have not done a taste test.. I usually don’t lick unknown fluids... lol. But that is a good idea to run the ac. It was cold and snowy today but I’ll let it run with the ac on tomorrow. I’m kind of thinking it may be the def..? Not sure if any of that system runs up towards the motor tho.

Depends where your drain tube is "aimed" at, hope that makes sense.

 

Sometimes it is set up aiming straight down, so water will hit the frame rail and go where it wants too, sometimes it will be in a different spot. You can adjust it by hand to go where you want it to drip.

I don’t think it’s that cause it does have a oily feel to the fluid and a very distinctive smell to it but I will look at that as well.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
