right now I think the oil will take the factory wax right off my frame.

Oil itself shouldn't hurt the wax, since both are petroleum-based.   It's the solvents used to thin down the oil that might be a problem.

Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

I don't know, I've seen a lot of things hurt the wax on these frames, it's hardly on there in the first place. Whenever I do an oil change I have to re-apply Undercoating where the oil hits the cross member under the drain plug. It takes the wax right off.

When I was looking for a product to remove the frame wax, I found that XYLENE quickly dissolves it.

If my frame was brand new and free of rust, I would probably maintain the factory wax using an aerosol can of the same product.

Since my frame was heavily rusted, I chose to dissolve the remaining wax, and prep for paint. After coating with POR-15, I then applied Rust-Oleum Professional Undercoating. I spray fluid film inside the frame and touch up the outside with the Rust-Oleum as needed. Looks like it’s gonna average out to be about $20 a year in products to maintain it.

Anyone try Cosmoline?   https://www.cosmolinedirect.com/cosmoline-rp-342-heavy-spray-military-grade-rust-preventive/

Cosmoline is some nasty stuff.  Had to clean that off equipment that we got in while I was in the Air Force.  Sticky nasty stuff that was hard to get off so it would be great but then it would also attract dust and dirt.

 

AMSOIL's Heavy-Duty Metal Protector would be a good choice to coat underneath a vehicle.

I've used it and I like it, goes on a little thicker than the Amsoil or Fluid Film. Seems to last a little longer. Then again with it being thicker it may not weep into the various crevice (that those other companies claim is important).

 

And I agree, you can't stop rust, but you can slow it down quit a bit with effort. One good thing...it takes a lot to rust these frames to the point where it'll fail inspection or need a piece welded in...so yearly maintenance should only help.

Need some advice. Almost through third salty winter on my 16 1500. As soon as mid April rolls around I plan get some of the daubert x12 stuff, wire brush off as much as I can, and spray the heck out of my frame. Once that is done, I found out there is a Known shop just down the street from my office. The daubert should make the frame look better cosmetically, and hopefully the Krown treatment will keep everything from getting any worse. How does my plan sound?

I spent a ton of time and money on rust mitigation for my heavily rusted 2014 frame. I used a needle scaler, grinder, wire wheel, strong solvents, rust pre-treatments, spraying POR-15 and then rubberized undercoating. I easily put 50 hours of labor into it only to have the frame totaled 5 months later in an accident. I wouldn’t do it the same way again.

If I was you, I would start by degreasing and power-washing the frame. Then use a hand wire brush to get any rust chunks off. Then spray Rust-Oleum Rust Reformer on the spots that are rusted. After that’s done and dried properly, I would spray Rust-Oleum Professional Rubberized Undercoating on the entire frame, even over the wax. That product adheres very well but can have a chalky appearance so I would top coat with the non professional version of Rust-Oleum Rubberized Undercoating which is a bit darker and sticks well to the professional version.

Definitely get the truck sprayed with Krown. If you notice more wax falling off later on, I would spray it with the rust reformer and rubberized undercoatings rather than more of the Daubert Nox-Rust X121B.

STOP! [emoji1630] Do not recommend doing ANY RUBBER COATINGS! They hold moisture and without realizing it you’re actually making it worse! There are special chemical applications available but prevention is the key such as ACF50 Anti-Corrosion. In addition, look up special marine application paint, used on ships, protecting against sea water and air too

You said rubberized coating spray. Any rubberized coating used to cover metal will trap moisture completely rusting out the frame. Look into the Marine Grade Primer and Paint, excellent results

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
