who the hell decided to change the front defrost vent in the NBS trucks? This crappy litttle 16 inch vent in the middle of the windshield is completely useless when its -15F and snowing. I get huge accumulations of ice along the sides of the windshield even with the heat/blower on max on defrost only.

 

anybody else with this issue?? Cant say I've even experienced this problem on my 06 no matter what the weather

 

sorry, just venting

Been through 1 winter in my GMT-900 and I havent noticed any difference between it and my old GMT-800. We hit about -5 last winter and got a bunch of snow.

Sceptre, you are not alone. The absolutely worthless central defroster vent is horrible and whoever thought of this design should be looking for another job. I KNOW Im not the only person with his problem, when its snowing in Anchorage, I pull up to a red light in traffic and have to get out and slap the wipers on the glass to make them work without icing over. Then I look around and see a bunch of GMT900 Tahoe/Avalanche/Silverado/GMC/Yukon owners doing the same thing. Kinda like we are part of an elite class that bought new trucks to find out the winter R/D wasn poorly performed.

I actually have no complaints with mine, was caked with ice and snow the other day along with nasty weather. I didn't even attempt to clean it, after I let it warm up it kept the windshield completely free of ice and snow.

4 of us at work just "upgraded" from 2006 2500 gas pickups to 2011 Duramax's....we ALL have the complaint and our shop engineer is actually looking at making some modifications to enhance flow direction.

 

I live in north-western alberta so maybe its a northern problem :cheers:

I too live in "blizzard land NY aka lake effect central" and we get snow by the FOOT off Lake Ontario ! I can say the center only defrost vent does a poor job keeping the windsheild clear on the sides during heavy snow events and snowplowing duty!

 

But I can say the same with my dads Dakota pickup with its center only defrost vents that also has the same issue !

 

Thankfully NAPA has finally started stocking the rubber covered "pinch mount-beam blade" replacements for the piss poor and worthless OEM blades so no more beating the ice and snow build-up off them every few minutes!

 

Thankfully these trucks have heated mirrors and rear window defoggers!

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Has anyone run these on their 2500?

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
