  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. My 2015 2500hd diesel has been in Auto nation in Coral Gables dealer for 2 weeks now. It all started with moisture every morning on the interior of my windshield, leading to constant fogging I started emptying out truck and low and behold, I found that the trucks, front Pass rug soaked in water under my waterproof mats, rear rugs were encapsulated in green , white mold and the back seat engulfed in whit mold under the sheepskin covers, which explains the issues I have been having with the radio touchscreen as moisture and mold permeated the whole cab. I took it to the dealer, that until w days ago said the truck did not have any leak, that they used a pressure washer to test and could not find any. So I took to the internet, and found several hundred complaints about water leaks coming from inside of the rear vents behind the back seats that the rubber flaps failed. GM has knowledge of this issue and vent failure but has done nothing about except to replace them with the same defective vent, pursuant to warranty. In my case I will not let that happen as the entire interior has mold that is visible and also spores that cannot be seen. The car is still under factory warranty that has to cover complete replacement to reinstate condition back to condition it was in when I first bought it. I can tell this is going to be an issue, and I have been advised by my counsel to document all interaction in writing, but the only reply from dealer has been an acknowledgement that the leak has been found and that the will contact me regarding repairs. NO OTHER CONTACT HAS BEEN HEARD TO DATE> I cannot fathom the excuse, as there is none. Bad Mojo around this recurring issue GM has not corrected. I am at my wits end my truck only has 9000 miles and sticker was well over &70K. TIME FOR A FORD.
  3. Ok so I want to put a post together about the onstar, XM, sharkfin, and whatever else antenna we have on the K2xx platform. I know there have been water leaks plaguing all years from 14-18. All the posts here I have seen, don’t really have any info or “the dealer fixed it”. A lot of people have commented that there is a break in the seal in the rear of the antenna. Please understand that is not a water seal for water intrusion into the cabin. That is only a rubber trim from the plastics of the antenna to the metal roof skin. There is a foam seal that goes around the wires and the mount that does all of the sealing of the elements. When the foam seal deteriorates is when the water issues start. I will explain with pics a little further down in the post. So I have a 14 Denali, vehicle was Daily driven, until 2 months ago, has 90,xxx miles on it, sat out side during the day, and garage kept at night. I have never had any water issues from the antenna (or the 3rd brake light for that matter) Here you can see the square seal around the home in the roof was still sealing with no issues One of the reasons this post happened was because I found a color matched shark fin brand new for VERY cheap. And my Denali has the black plastic fin from the factory.
  4. Has anyone noticed that the hood on the 2016 Silverado 1500 pools water on the hood? I contacted Chevy. They suggested that I also contact local dealer who claims that no one else has mentioned this problem.
  5. 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?
  6. 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.
  7. Has anyone installed a water/methanol inject kit on any of the small blocks (2014-2018)? I personally have the LV3 4.3L V6. Looking to eliminate the carbon build up, caused by direct injection, on the intake valves. Right now I'm trusting that Sea Foam is doing the job every 30k miles. EDIT* I'm also interested in the increased performance after tuning. I am aware that a catch can would eliminate the majority of carbon build up on the valves.
  8. Last night I found my passenger side carpet saturated with water in my 2015 Silverado 1500. I lifted the carpet up and found the underlay soaked and a pool of water in the floor pan. After searching the internet I found this is a common problem with many potential sources. The shark fin antenna, leaking seams behind the front fender, through the firewall, and from under the cowl by the windshield wipers. I don’t think mine is coming from the radio antenna or from behind the fender as it is running straight down the firewall from behind the glove compartments. It is raining steady here today and my truck has not moved and it is a steady stream running from behind the glove box. Does anyone have pictures or a better description of where I should be looking on the firewall or under the wiper cowl?
  9. If this is posted in the wrong spot, please let me know as I am new. I am looking for some advice from some other guys who have gone down the same path I am about to go down. I have a 2015 Silverado 5.3 and next week I am ordering an on3 76mm ball-bearing turbo kit for it, Snow Performance Stage 2 water meth kit, 4'' exhaust and a converter (not sure the stall, HELP!) My goal is 620-650 rwhp. I have a friend who put down 614 on meth with a 70mm kit and a 3200 stall precision converter. My questions are this because I am not as familiar with this L83. What will factory fuel support? will I need a pump/injectors to get in the low-mid 600s? What would be a good converter to use on the street but also still be able to pull an open trailer with my sidexside (RZR XP Turbo) on it? Who has experience with On3 turbo kits? Vengeance Racing, a very reputable and trustworthy shop here in Georgia will be dyno tuning the truck for me once I am done. Thanks guys!
  10. Recently replaced my Thermostat and water pump and radiator cap now I notice the temperature gauge jitters around regardless of if the engine is cool or warm. there is also a pinhole leak in the radiator near the oil cooling inlet hose. Before I get a diagnosis/opinion I feel I should state the radiator has that Bars Copper flake stop leak in it and I tried to patch the leak on the outside using JB Weld (neither of which worked) My theories are #1 The Stop Leak has somehow stopped the thermostat from completely closing or the thermostat was faulty when installed (thermostat been installed for a month and this problem has only been happening for 3 days) #2 the radiator leak is causing it (yet again the leak has been present much longer than the gauge jitter. #3 there is air stuck in the cooling system. Going to replace the thermostat this weekend and the radiator within the next month but wanted to ask is there anything else that could be causing this issue
