I did a coolant flush on my 5.3 '03 Sierra and changed the fluid from green to Prestone orange coolant. I had mild overheating issues prior to the flush, so I figured flushing the coolant and changing to orange Prestone might help (I did the same exact thing in my '04 GTO with LS1 and haven't had overheating issues since forever).
Now the temp always goes above midway, and here's the thing... It does the same thing even on the HIGHWAY with fans on high speed, and it sometimes goes down in traffic only (basically when I'm not giving the engine any acceleration).
I changed the coolant again with dexcool, and did an air bleed, changed the temp sensor and thermostat two months ago, and cannot see any leak from the pump but still nothing is helping.
I'll note that the green coolant didn't look dirty when it I flushed it out, and that it only heats up when I'm accelerating.
Im sure this might have been covered someplace else but i couldnt find it. I have a 2015 gmc sierra 2500hd sle. The person who owned it before me installed cheap aftermarket tow mirrors and they jiggle all over the place on the highway. I would like to get some better quality mirrors. I'm just wondering if my truck supports the marker lights, blinkers, and reverse/cargo lights plug and play without making my own connections.
First post here and I wasn't quite sure where to post. This isn't really troubleshooting because we know what is wrong, I'm mainly wanting to know if there are large scale issues regarding this and how do we get in touch with GMC about it as our mechanic isn't much help at this point other than charging $1100 to fix it.
We bought a used 2015 GMC Yukon last year with 20k miles on it. A month ago, the Side Blind Zone alert on the side mirrors came on and have stayed on permanently, even when the car is turned off. Because of that, it drains our battery when the car is parked longer than 2-3 days. I took it into the shop a couple of days ago and we find out that the box that houses the sensors, in the right rear quarter panel, had become detached and was dangling close to the exhaust pipe. Because of this, it totally melted the box housing the sensors. The mechanic tells us that the sensor box is only glued in and can become detached easily. This is costing us $1100 to fix because the sensor is over $300, and then labor for the past 2 days to get it back in place.
Is there a thread in here from others who have had this issue? Is this a wide spread issue? Should GMC pay to fix this and if so, what are my next steps?
Yes i just bought a 2015 gmc sierra in kentucky and the truck after purchase turns out the truck was from canada and i bass fish and when at the ramp i need to be able to turn my headlights off but apparently they have a law where the headlights stay on. Is this a programmed thing or is there something i can do to fix them. Any help would be much appreciated.
