Zane & Josh, The Merva Brothers Co-Founders, GM-Trucks.com October 2018 Pickup utility racks have been an option for anyone looking to haul around longer objects for decades. They've gotten the job done when stuff like ladders, wood, and canoes needed moved from one place to another. With the options of bed sizes shrinking over the past few years, a stylish and functional utility rack can add, well , a lot of utility to your full size or midsize truck. Unfortunately, not many racks look as good as they function and take away from the aesthetics of our vehicle. So, when we found a new aluminum utility rack that looked as professional as our truck, we wanted to try it out. In an effort to find a stylish utility rack we're reviewing the Agri-Cover ADARAC Aluminum Series. What is it? Agri-Cover ADARAC Aluminum Series Model Number 4001238 For 2007-2013 Silverado/Sierra 1500 with 6' 6" bed MSRP: $491.30 / $578 MSRP (as of October 2018) Manufacturer Website: https://www.agricover.com/truck-bed-racks/ Installation Time: 1-hour Installation Difficulty: Easy with basic mechanical skills and a helping hand Main Features Rust resistant aluminum construction No drill installation Compact and narrow upright designs Four load dividers included Compatable with Access-Cover bed covers What We Like Modern and stylish brushed aluminum design Thick stamped upright supports are super staunch Modular attachment points and accessories Uprights can be removed or installed with one person 500-lb capacity What We Don’t Like Stamped parts have sharp edges out of the box Can't re-position uprights without tools Rack as a whole can restrict what you put in the bed unless removed Tie-down holes are only barely bigger than a standard hook ADARAC Aluminum Series Unboxing The ADARAC came securely shipped in a long and moderately heavy box. One person can move the packaging around but two would be easier. We started out by unpacking our rack, laying out all of the parts and reading the manual. We found hardware packaging was excellent with no missing parts. The manual was clear and easy to understand. Nothing was scratched or damaged. The stamped aluminum uprights came covered in a protective sheeting/fabric and looking as if they were straight out of the forming machine. We almost cut ourselves on the uprights because no clean up work had been done to remove burrs or sharp edges. A smooth edge would have been a lot better and easier to handle. Once everything was organized and we had familiarized ourselves with the installation manual, we started to get to work. ADARAC Aluminum Series Installation We installed this rack at the same time as our Access-Cover Lorado Roll Up Cover. If you're doing something similar, don't make the same mistake we did and try to install the rack before the cover. It won't work, as the ADARAC blocks the bed-stake holes when installed. The same stake holes you need access to for installing the Lorado, so install your bed cover first. Speaking of...check our our full review of the Access-Cover Lorado here After getting ahead of ourselves, we detoured and installed our cover before coming back to the ADARAC. The first step was to lay down the side rails and secure them to the stake pockets on the bed using compression style fittings. The attachment method is slick, requiring no drilling or cutting. It's also fully reversible and doesn't damage your bed. Best of all, the rails are never going to move. The first step is to drop the compression plates into the stake holds and tighten down the rails with two clamps/bolts per rail. Then we measured the distance between the installed rails on the bed and set the uprights at the same distance on the floor. We used some old shop towels to prevent scratching the pretty aluminum. Next, we attached the crossbars at the measured width making sure to center everything up. We then tightened the assembled front and back racks on the ground before lifting them up to the truck bed. A few bolts and adjustments later... our racks are on the truck. The best part about aluminum racks is that the front and rear sections are light enough for one person to install or remove them without help. The rear upright mounting bolts are in a tight space when installed with a bed cover and we couldn't use a socket wrench to tighten them down. And before we knew it, our Sierra had a new utility rack and bed cover. Total installation time took right around one hour and was easy enough to do with one person but would be quicker with two. ADARAC Aluminum Series Final Thoughts An entire summer has gone by since we first installed our ADARAC Aluminum Series Utility Rack and we've been extremely glad we've had it as a tool on our GMC. We've used the ADARAC to help build a new bathroom, take our canoe to the local lake for a relaxing afternoon, and moved our ladder around to help with projects at home and work. The ADARAC has conquered every task we've thrown at it. It's never bent, felt flimsy, or failed to hold our cargo firmly in place. Basically... exactly what you want from a utility rack. The brushed aluminum finish and sleek stamped uprights also look good too. If the $500 price tag is too much, Agri-Cover offers the standard version of the ADARAC which is constructed with steel instead but uses the same basic design. Or, if you need a little wider load, the ADARAC Aluminum Pro Series is designed for larger objects and capacities. If you're in the market for a good looking, well functioning and indestructible utility rack for your truck, we recommend you look at the Agri-Cover ADARAC Utility Rack.

Hello all! I went to start my 2005 Sierra earlier and noticed it said "service air bag" on the odometer. Before calling the dealer to service it I was just wondering if anyone had any experience/tips/advice? I've never had a vehicle require that. I was just wondering about stuff like whether it will cost money to service it or anything like that? Thank you guys in advanced for your input!

Just changed the oil on my 2014 gmc sierra 4.3l. It required six quarts of oil which is what i used but now i am afraid if its overfilled or not. Its a completely different reading than what it was before the oil change. Althought its not above the hashmarks there are 2 dots on there which I’m not sure if those are the oil level indicators or the hashmarks are the oil level indicators. The dots are kinda hidden which is why I’m not sure if those even are oil indicators dots. Im really hoping i filled it up correctly and wont ruin the engine by overfilling the oil. I installed a fumoto valve so it could be easier to drain excess oil. I do note there was a metallic ticking noise that was present before the oil change but disappeared afterwards. following picture (2) is before the oil change one of each side of the dipstick The next two fuller looking ones are after the oil change one for each side of the dipstick

Zane Merva Executive Editor, GM-Trucks.com 3/5/2018 With the debut of GMC's all new and very fancy MultiPro Tailgate last week in Detroit questions have been floated regarding various aspects of the design and how available the tailgate will truly be. So, we reached out to GMC directly and have some answers for you. Here we are in no particular order: Will the MultiPro be available on any trim level other than SLT and Denali? YES. Although only the SLT and Denali trim levels were mentioned last week, we can confirm the MultiPro tailgate will be available on the SLE trim level as well. Can I open the MultiPro with the keyfob? YES. Just the tailgate as a whole, however. There's no option to open the inner section unless you do it with the button on the gate. Will the MultiPro prevent itself from opening into mounted ball hitch? NO. This is the biggest issue we can see with the MultiPro going forward. The inner gate is fully susceptible to damage from a mounted trailer hitch. GMC does mention that a warning sticker will be present to remind owners not to do just this. Owners will have to remember going forward that if they leave a ball hitch mounted, the MultiPro WILL HIT IT. Will GMC offer a manual (cheaper) version of the MultiPro later on? UNDETERMINED. GMC wouldn't answer our questions about a cheaper, manual version of the MultiPro in the future. We think it would be a great idea and GMC punting the question means the option is in play for the future. Will Chevrolet ever get the MultiPro? LIKELY. Although no-one from Chevy is talking, we expect the Silverado to get the MultiPro (or a Chevy-named version) at some point in the near future, perhaps in model year two (2020)

The only way for the gauge cluster to work is by pressing, and holding down the reset button on the cluster, like why? If I don’t nothing works

Now that owners are taking delivery of the new 2019 Chevy Silverado and GMC Sierra, I thought a quick reference guide to common routine maintenance items would be beneficial to us all.

2014-2018 Chevy Silverado's and GMC Sierra's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are GM bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(Bulletin 15829) This is not true of the 2015 like mine although they use similar verbiage in the bulletin P11513A and P11513F. This problem can also exist in 2016-18 models according to what a mechanic told me. It should be noted that Bulletin P11513A and F also applies to 2015 Cadillac Escalade Models, 2015 Chevrolet Suburban, Tahoe, 2015 GMC Sierra Denali, Yukon Models, Yukon Denali Models Equipped with 4.3L, 5.3L or 6.2L Engine (RPOs LV1, LV3, L83 or L86). Anyone regardless of year and mileage with this problem needs to report this to the National Highway Traffic Safety Administration (NHTSA) using the compliant form ( https://www-odi.nhtsa.dot.gov/VehicleComplaint/) or calling the hot line at 1-888-327-4236. With enough complaints the NHTSA may force GM to issue a recall or provide extend coverage. Even if you have had this repaired filling a compliant may get you reimbursed for your costs. Another option is to file a compliant with the Better Business Bureau. They have a compliant form on line just type in BBB Car-Truck Compliant in your search engine. It will not hurt to file a compliant with both the BBB and NHTSA. Although If you are going to do this file with the BBB first as they will not accept your compliant if you file with the NHTSA first. 2015 Radiator PI1513A.pdf 2014 Radiator Special Coverage 15829.pdf GM Bulletin P11513F January 2019.pdf

Just curious if anyone has the same issue I've been having. So on the very first shift of the day from 3-4 my trans seems to slip into gear. After the initial run through the gears it shifts great every single time after that. I have real basic stuff done to my 14 Sierra..cold air intake, cat back exhaust and blackbear tune (yes the trans was tuned). It really seems to be temperature related because it gradually got worse the colder the nights get (I live in the northeast). And no matter how long I let the truck warm up before I drive it, it does the slip but only 1 time. Not sure if this is also related but the tuner said the torque converter locks after the shift into 4th gear.

Hey guys, I have a problem I can't solve and I'm hoping someone here can help. Last night I was driving my 2011 GMC Sierra 2WD 5.3L and pulled into a gas station. When I got back in the truck I turned the key to the start position but nothing happened besides the dash going black. I didn't hear the starter click and I didn't hear the fuel pump turn on. So far here's what I've done: Tried to jump the car, no success. Took the battery to get tested and it's fine. Switched the relays around to see if something else would quit working and the truck would start, but same outcome. I jumped the two big connectors on the back of the starter and the starter turned over, but the truck never started it actually kept turning even with the power off and didn't stop until I disconnected the battery I replaced the battery in the remote but this didn't fix anything. I thought it might be anti-theft related but the the light on the dash isn't on for the alarm and the truck locks and unlocks with the remote. I connected a scanner to it and am able to see the ecm getting an ignition signal when I turn the key to start Through the scanner I can see that the ECM recognizes that the transmission is in park/neutral Has anyone ran into this before? Is there anything else that would prevent it from starting and cause a no crank, no fuel, no start issue that I need to check? The monitor I'm using has the ability to check basically any sensor value. Thanks!

So I just got a 2014 Sierra SLT, and I'm wondering, is it compatible with the 2016 Sierra Denali? I have access to one for parts and was hoping if someone could tell me if it's even possible to. Body on the 16 is gone, but the trans and engine and some of the interior is still usable.

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.
