  1. https://gm-techlink.com/?p=9439 Proper Coolant Level on the 6.6L Duramax Diesel Engine February 21, 2018 A Low Coolant message may be displayed on the Driver Information Center of some 2017-2018 Silverado and Sierra models equipped with the 6.6L Duramax diesel engine (RPO L5P). An inspection of the radiator surge tank may appear to show a low coolant condition. The low coolant level in the radiator surge tank may be due to the fill process at the assembly plant, which cannot purge all of the air from the cooling system and the surge tank. After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. Coolant Levels During a Pre-Delivery Inspection (PDI), the coolant level may appear low, but is at a level high enough to keep the Low Coolant message off. During PDI, coolant should be added to fill the upper chamber of the radiator surge tank. (Fig. 6) Fig. 6 A coolant level that is low enough to turn on the Low Coolant message will be below the horizontal line across the radiator surge tank. (Fig. 7) The horizontal line is a baffle inside the surge tank that keeps the coolant from sloshing inside the tank and tripping the coolant level sensor, which is located below the baffle. Fig. 7 A full coolant level will show the coolant at the bottom of the radiator surge tank fill neck. (Fig. Fig. 8 Filling the Tank If a low coolant level is found, add one quart (0.946 liter) of Dex-Cool® coolant to the upper chamber of the coolant surge tank in order to bring the level up to the bottom of the surge tank fill neck. TIP: The L5P diesel engine radiator surge tank has two different surge tank caps. The fill cap used to fill the system is located on top of the tank. It is a non-pressurized radiator surge tank cap with left hand threads.
  2. I do, but the order guide calls them roof lamps.
  3. The hazards: NHTSA says that if the diffuser component separates from the inflator during airbag deployment, the performance of the RRAB may be degraded, increasing the risk of injury in the event a crash. Affected vehicles: 2020 Buick Enclave 2020 Cadillac XT5 2020 Cadillac XT6 2020 Chevrolet Blazer 2020 Chevrolet Silverado 1500 2020 Chevrolet Silverado 2500 2020 Chevrolet Silverado 3500 2020 Chevrolet Traverse 2020 GMC Acadia 2020 GMC Sierra 1500 2020 GMC Sierra 2500 2020 GMC Sierra 3500 Affected parts: Roof-Rail Air Bag (RRAB) diffuser, airbag inflator. Number of affected vehicles: 769 With that many vehicles involved, I'm surprised it's not more than 769 units. They build a lot more than that in a day.
  4. Extra capacity, as in holds more dirt and debris, not as in higher airflow. At least not more airflow when new. Maybe more flow remaining when they have collected 'xyz' ounces of dirt/debris.
  5. Just F*&%Yg stop. If you want to argue about what someone else should or shouldn't drive, start your own g(*&^ *m thread.
  6. Did you try to use search to find the 'missing' tunes? Sorry, I'm just guessing.
  7. I've had about 15 or so GM vehicles (usually 2 here at a time, sometimes there have been 3 or 4) and I've never had to replace an actuator. A good percentage of them ending up being high mileage vehicles, well out of warranty. I think I've had to 'reprogram' the window in one of the trucks -- after trying to operate it when it was frozen in place due to freezing rain. I'd say that it's not common at all. YMMV
  8. Sometimes steering issues are caused by the tires/road rather than the alignment/road.
  9. They are also included in a bunch of 2500 optional packages. (might find the code for the package, but not see UO1 in the listing) 2500 GMC U01 Lamps, Smoked Amber roof marker, (LED) Sierra - Not available with (YF5) California state emissions requirements. SLE - Not available with (YF5) California state emissions requirements. Included with (PCQ) SLE Convenience Package. SLT - Not available with (YF5) California state emissions requirements. Included with (PCY) SLT Convenience Package. AT4 - Not available with (YF5) California state emissions requirements. Included with (PDO) AT4 Preferred Package. Denali - Std, but not available with (YF5) California state emissions requirements. 2500 Chev U01 Lamps, Smoked Amber roof marker, (LED) WT and LT - Included with (ANQ) Alaskan Snow Plow Special Edition. Not available with (YF5) California state emissions requirements. Custom, LTZ and HC - Not available with (YF5) California state emissions requirements.
  10. If it's changed again that quickly on it's own it may be binding or have some other problem. Time to make an appointment so it can be diagnosed.
  11. Not as long as the seat can be pushed far enough back for the legs, and the steering column can then be extended enough to suit the arm length. I always figure pedal adjust was more useful for those with short legs that wanted to be further from the dash. The firewall doesn't move, and with 'non-moveable' pedals, wide open throttle is with the pedal against the firewall.
  12. And to make it even more fun, the 2020HD standard box is a little longer than the 19/20 1500 standard box. 2019 HD standard is same length as 2018 and earlier 1500 std.
  13. CP4 failure isn't a derate thing. It's walking vs riding. How's the rest of the truck? If similarly equipped vehicles, it sometimes makes sense to calculate the $/mile (km) to upgrade. $25,000 / (180, 000 - 30, 000)km = $0.16/km Converting $ and distance to US 150,000km approx 93,000 miles $25k Cdn approx $18,500 US 18,500/93000 = approx US$0.20/mile US equivalent In Ontario, annual registration is the same $ for new or used.
  14. If planning to get another vehicle, be sure to figure in the tax treatment in your state/province. In Ontario we pay a combined federal/provincial sales tax on the 'difference' in the price of the vehicles. And it's 13%. So, trade a $50K vehicle on a $60K and pay tax on $10k -- so $10,000 x 13% = $1300. Total deal $11,300 to change vehicles ($10,000 + $1300) Sell the $50k vehicle to someone else for $55k, then buy the $60k one from dealer. Pay tax on $60k -- $60,000 x 13% = $7800 Total deal $12,800 ($5000 + $7800) In this case, it's better to trade to dealer. YMMV Obviously depends on both the tax treatment where the transaction occurs and differences in the trade-in value vs sell-it-somewhere else numbers.
  15. Have you tried the window programming routine? Programming the Power Windows Programming may be necessary if the vehicle battery has been disconnected or discharged. If the window is unable to express-up, program each express-close window: 1. Close all doors. 2. Turn the ignition on or to ACC/ ACCESSORY. 3. Partially open the window to be programmed. Then close it and continue to pull the switch briefly after the window has fully closed. 4. Open the window and continue to press the switch briefly after the window has fully opened.
  16. Settings in audio in personalization maybe? . Reset Music Index: This allows the music index to be reset if you are having difficulty accessing all of the media content on your device. Touch Yes or No.
  17. I was assuming there were 2 towers. What I was wondering was are the towers only attached to the tops of the bed rails, or do the towers have structure to put the load (or part of it) directly to where the bed mounts to the frame.
  18. 2019 pickup the L87 was in SLT /AT4 / Denali / LTZ / HC, so usage has expanded.
  19. On the pickup side, for 2021 the L87 is available on SLT / AT4 / Denali / Custom TB / RST / LT TB / LTZ / HC
  20. This is southern Ontario. What is the August discount in your area? The HD's it's 10%, up to $9000. 15% OF MSRP = UP TO $11,500 CASH PURCHASE CREDIT ON ALL 2020 SIERRA 1500 MODELS BASED ON MSRP OF $76,66710 + MAKE NO FINANCE PAYMENTS FOR 3 MONTHS^
  21. Does the rack apply all the load to the top of the bed sides or is there other structure not visible in the pics?
  22. Truck looks great! Eye not so much. Last truck that I took for Line-X is was a 'while you wait' deal. Surprised you need to leave it overnight. (nothing against Line-X, but I've since become a fan of the factory spray-in) All seems like quite a task to take on in the few weeks before a huge re-location. Hope the rest goes well.
  23. Also depends on what vent locations (and fan settings) are being used for the A/C. As previously posted, effectiveness depends on how cold the air is that is near the intake for the seat ventilator.
