  1. I have 2014 Silverado crew cab and I’m noticing water leaking from under the dash. We had a pretty good rain today and I go to get in my truck and my floor mat had a good amount of water sitting on it and I could see water dripping from up under the dash. Good thing I have weather-tech mats. But I’m running into dead ends trying to figure out how it’s getting in. It’s not the sunroof, it’s not the fin (my headliner isn’t getting wet so it can’t be the fin?) I’ve checked my pillar while it was raining and no water running down it. I read something before about a guy who had a bad weld under the cowl could be letting it in? Or could it possibly be the edges of the windshield leaking? Just looking for any answer here. When I look up under the dash to see where it’s coming from I can see that there is a opening where the leather and firewall material were cut from the factory and it is wet when I put my hand up there, like the material used for the firewall is wet. But my question is, how is it getting there? I will upload pics tomorrow for reference to what I’m talking about. Thanks ahead of time.
  2. Hello Anyone. i have a LBZ Duramax, and i have just put in a new water pump and rebuild the oil cooler and the pipe that connects them i put in after and i pitched a gasket and it eakd then i took it out again and put two non OEM gaskets on there and it seemed to stop leaking when i added coolant but when i fired it all up it pissed out again so my question.. what is the propper way to put the pipe in, i could no imagin putting it in the cooler then putting it back on the truck, do you put it on the water pump first maybe then put it in??? or can you some how use gasket maker instead??? i need help
  3. I have 2014 Silverado and went to the gas station one morning and out of nowhere started smelling gas inside of the truck. Long story short, went to look underneath truck and had a 3x3 ft size puddle of fuel underneath truck on ground. Looked to see where it was coming from and looks like it’s coming from back side of motor. Can anyone help or recommend any action to take from this?
  4. Hi everyone! just hopped into my first GMC Sierra 2020. Traded in my 2017 Tacoma which went 80,000km without an issue. 2-days in now and I’ve got an engine light, and clear water leaking from underneath the truck. It’s leaking from the joint with the two tubes which I’ve attached a picture of. Any thoughts on what this is?? I’ll be calling the dealership but just want to see if this is common? also... anyone else notice the poor undercoat? Used my thumb to rub the undercoat right off to steel...
  5. So finally finished my truck. 2014 Sierra Single cab L83. GPI stage 2 cam kit, DOD delete, LS7 lifters.... 2.9L Whipple with a 4inch pulley Stock convertor Full exhaust Tune Got 517whp... Everything was running perfect untillll.... Started losing power, and quite a bit. Took it back to the garage, they tested pipes, vacuum, all seemed to be in order. Later found 3 spots where there were leaks im my exhaust where the headers connects to the y pipe and out the y pipe to the catback, they were clamped... So got flanges and bolted them on... All perfect... Still running 7.3psi high boost and its beginning to frustrate me. I also get rpm drops in 2nd gear at 4500 and above (this has been happening ever since i added the cams before having the supercharger) - doesn't happen everytime, but happens more often than not. Any suggestions? Any ideas? Oh i also have a gear oil cooler installed... Recently serviced everything, gear oil, diff oil, engine oil, spark plugs, changed the wiring to the MSD and added a heat shield to be safe.... Something is wrong and its quite annoying. Note: its hot AF where im at - Dubai... Easily hits 45degrees C during the day with insane humidity levels... Any feedback wld be helpful... Thanks Im going for a compression test tomorrow to see if that is fine.
  6. Truck drives fine but obviously it isn’t good. Haven’t noticed any oil puddles on the floor or any big leaking. What you guys think it can be? Here’s a pic.
  7. I need help figuring this one out, I just bought this Yukon XL (100k) and drove it home (about two hours of driving) and I had a fluid puddle on my driveway the next day. So I checked it out and the only spot where I could find any “leakage” was from the drivers side motor mount. There were no other apparent fluid leaks or spills from anywhere else. I took it in to have it looked and and the liquid had dried and only left minor stains. He thought I was crazy at this point. I asked the tech if he could check the parts listing to see if it was fluid filled. He came back with a engine mount checklist which states to check for fluid leaks from the mount if equipped with GLYCOL(i.e. coolant) but also said he doesn’t see any signs of a leak even after I showed him pictures and he pulled up the inspection checklist. I need proof that the mount needs replaced because the fluid has leaked out. GLYCOL dries to show very little sign of leakage. How much fluid could he expect the mount to hold to keep leaking? How can I know for sure that this mount is the fluid filled kind or not? I took pictures of all of this.
  8. We we had some strong storms roll throught the DFW area yesterday for a while. When I finally got out to my truck, there was a nice puddle of water sitting in my All Weather floormat. Now I know why GM sells these - to keep your carpet dry from the leaky roof! There was several ounces of water down there = a large puddle. I traced it up the inside of the dash, up the A-pillar, and to a wet headliner. NOT HAPPY!!! This is the second time this has happened in my new truck. The first time was a few months ago and only a little amount, so I thought it might have been a fluke. Though I did bring it to the dealership to have them look at it. They spent at least an hour in the water bay, most of the time with me helping, trying to find a leak. They first suspected the sunroof drain, but rulled that out after several tests. Then looked around the front window, but couldn't find anything. But the window couldn't be the cause with the location of the wetness in the headliner without a strong headwind (like while driving). Both occurences have been while parked at work for a long period of time. Then I mentioned reading some issues with the OnStar antenna, so they ran a strong hose right up on it for several minutes - nothing. I told them I'd keep an eye on it and come back. Obviously it wasn't a fluke, and obviously there's a problem. Does anybody know what's going on? Why is there a gap in the OnStar antenna seal? For those that have had this fixed, did the dealership do anything different than just replace the antenna? Is there a new/better antenna design? Did they apply additional sealant? Is GM doing anything to address this? Has anyone applied sealant to the gap to fix this problem themselves? When they were looking for my leak, the did partially drop the headliner to inspect the underside of the roof. The antenna was installed tightly. I'm just curious if anybody knows what the real problem is? Or what the real fix is? Thanks.
  9. I have noticed the last couple of times we have had a steady rain I go to put my son in the car and the seat belt is soaking wet. A closer look reveals water dripping out the bottom half of the upper portion from where the seat belt is stored. The carpet is not wet, and I cant figure out how the water is getting in. It's only happening on the rear passenger seat behind the drivers seat. Anyone else having this issue?
  10. Good afternoon, I am attempting to chase down an oil leak on my 2005 Yukon XL with the 5.3. As far as I can tell, it is coming down the back of the block all the way from the top, and is leaving about a baseball-sized puddle on the ground overnight. I have replaced the valve cover gaskets, valley pan gasket, and installed a brand new oil pressure switch. What else could it be?? Could the camshaft position sensor be leaking?
  11. Well, I have a bit of a issue with water leaks in a new 1500 ltz z71. The history is, we keep it garaged most of the time so water leaks had not been an issue.. recently we had to do some remodel at the house and used the garage to store/cut wood. We've left the vehicle outside for several months. I kept noticing that we would get an occasional moisture in the windows as the temperature changed plus a slight odor of musk smell. Well, on a last year, we got a chip in the windshield that had to be replaced. Then after several torrential rains over several months, I noticed one day that my drivers side carpet was soaked. the water went all the way up the firewall. in the padding under the carpet. Naturally we suspected the windshield and had the company that warranty it come back and fix. after drying the carpet out with a small fan over several days. During the next rain (torrential) it was wet again. Again we called the windshield company and they removed / reinstalled the windshield again (3rd time) . This time while the windshield tech had the windshield removed I looked at what possibly could leak and where it would go down the inside firewall. There was only one way and it had to be due to lack of enough windshield adhesive in the upper left corner where the water could drip into the A pillar and down to behind the speaker then into the cab. While the windshield was out, I removed the A pillar trim so I can verify the windshield and also verify that the upper sat antenna wasn't leaking. Again I dried the carpet and parked the truck going down hill nose down. I took the water hose and flooded the areas we thought was leaking.... no water leaks. ok good. Just to double check that I didn't have another issue, I then proceeded to run water over the driver door seal area.. (I had removed the drivers sill molding and placed paper towels around the door seal bottom so I could see if it leaked) front door was not leaking. I then decided to "just for grins" check the rear. I took off the sill molding and noticed the carpet and the padding was wet back there.. I dried up the puddles of water, then tested the back door seal using same method. no leak. ok then I thought where in the heck would this water be coming from. After googling and watching a video of the rear body vent leaks, I decided to test the rear body vent on drivers side... by just letting water drip from the rear window down on the vent, and after a few minutes water started poring into the rear. Ah ha.. So this is where it is leaking... and it makes sense now, I have a bed cover and every time it rains water goes forward onto the cab and then drips onto the vent, the water penetrates runs under the carpet all the way to the drivers side if the truck is parked nose down. the carpet is wicking up the water that is why it is wet all the way up the firewall. Anyone owning a Chevrolet pickup needs to verify the rear carpet is not getting wet. Faulty or leaking vents could allow exhaust or other gases to penetrate into the vehicle as well as water. It would be so simple to put some sort of "outer water shield" over the outside of those flaps so water could not hit the flaps. This would direct the water downward and still allow the cab to breathe.. on installation seal the unit with silicone around the perimeter where it meets the cab metal so there would be a good seal on the unit. geez.. This needs to be a recall.. this is a faulty design and needs to be redesigned. I am taking this to the stealer next week as the vehicle is under warranty for 500 more miles.
  12. A few months ago I installed a set of Texas Speed and Performance long tube headers and the catted y pipe they offer. Some then ive noticed the front of the transmission pan leaks a little bit. The bolt heads have trans fluid on them all the time and every now and then it drips onto the exhaust and I can smell it. I believe this is due to the heat from the catalytic converter that is positioned directly below the trans pan. I haven’t noticed any higher trans temperature and the fluid level of the trans hasn’t gotten low so it not a bad leak, just an annoying smell mostly. I’m trying to decide what to do and I thought I’d get y’alls opinion. I was thinking about making a heat shield to go between the cat and the trans pan. or maybe just tightening the bolts on the trans pan, if I remember correctly the torque spec on those is pretty low and the added heat from the cat might be enough to make it leak. Thanks for any input.
  13. Noticed this leak under my truck yesterday. When i set the a/c on it goes crazy F2055D35-15F4-4CAC-8805-0E0043C030EC.MOV
  14. 2019 Denali ultimate. So far the ultimate headache ache. I’ve had the rear window leak, front glass removed and headliner replaced. Dealership left erase fingerprints all over new headliner. The rubber wasn’t tucked back in properly. Windshield had sealant all over interior and exterior. Botched job. They sealed rear window.. Now it leaks again In the same spot. I’ve turned into GM a claim and they sent to a senior advisor. I still Haven’t heard from the,. Left multiple messages, the dealer has left messages and no return calls. ‘’Also had the ECM replaced which was. 5 DAY PROCESS. Squeaks in dash that has been in twice until I finally Fixed it myself. Front speaker wasn’t seated good. The plastic piece on rear window exterior had to be glued on twice. Service engine soon light for something with transmission. And now also light on for service anti lock brakes. Since thanksgiving when truck was purchased it’s been in the shop for over three weeks. All I really Need is a customer service senior advisor to return a call and allow a rear window replacement at the dealership. Anyone have a connection? Regretting trading my f250. Could see where the Denali could be nice truck had it not been in shop every other week.
  15. Hello, This is a 1999 Chevy Silverado 5.3l, 4wd push button style, 4L60E transmission, 153k. I have a green fluid leak (T-case fluid) coming from the front axel input shaft seal, drivers side. It obviously gets thrown around all over surrounding components when driven in current condition. The leak will accumulate about 2 or 3 drips on the ground overnight. It's been going on for a good while judging by the amount of fluid caked on everything. I've only driven approximately 50 miles since i noticed issue, all in 2wd. My questions are whether or not i risk significant damage to the case if ONLY driven in 2wd while also adding fluid as needed? Also, is there an "inner" seal in the transfer case that will be exposed when drive shaft is removed from t-case? If so, what is the responsibility of "inner" seal and is there a reason it should also be replaced simultaneously? When i'm in that deep i'd rather do whatever is necessary and logical. Thanks for any help with stated questions and I also love to hear any related advice or experience! Taking it to a shop is not an option as I have little money and major trust issues. Trust issues stemming from several bad experiences in the past and most recently, pertaining to this vehicle. I bought this truck for $6,500, everything is in VERY good shape, recently had a 90k motor installed @ 150k (i purchased it at 152.5k) as a private party transaction from the auto shop owner who installed the second motor. Turns out recently installed engine either has a cracked head or head gasket as the black light test reveals coolant coming from exhaust among other confirmations... AAAGGGHH. That's a completely different story that's being dealt with but figured i'd share my reasons for NOT TAKING IT TO ANYONE mentality. Auto salesmen/mechanics can be total sleezeballs. From now on it's my way or the highway, to my own dismay haha.
  16. Dealer replaced front driver's side axle seal (p/n 22761722) under warranty at 25K miles due to dripping, throwing oil under driver side of 6.2l engine. Anyone else have this problem? What is root cause?
  17. Hi guys, Anyone had the chance to remove these roof racks from their car? I just want to look underneath as I suspect I have some minor leak underneath Do I need to remove the headliner to do this? Thanks

  19. Hey guys, I have a 2007 Chevrolet Silverado LTZ with the 5.3 L engine. Truck has over 300,000 km now. Just fixing up some odds and ends on it, and I noticed I have some red transmission fluid dripping from the small inspection hole at the rear part of the transmission bellhousing (right before the pan). I have attached a picture. Any ideas where this would be coming from? Thank you!
  20. What the heck is this on the rear transfer case half and why would it be leaking? Obviously corroded, but why does it go all the way through? Replacement case halves do not show any holes there. Ideas for fix?
