I am replacing San near everything on mine. We are getting rid of the Dodge 2500 and mine will be the strongest and the primary tow vehicle

Alright, emailed Performance accessories and they said their body lifts are designed to work with hydroboost, and the stock lines for it, which is the good part.

 

Now, here is the weird part. I look up parts (actually, mostly hoses) for the P/S pump to hydroboost, and then hydroboost to steering gear, and also return line. I keep getting different part numbers off different websites. I look up the parts on ACDelco.com first and then I was just on gmpartsdirect.com and get their part number, then I go back to ACDelco and use their cross reference search for parts, and it shows it with a different part number than the one I originally found on the ACDelco website? Can anyone help me out with specific parts numbers? I keep finding different ones, so I'm getting really confuzed.

Now yous said to look for parts off of a 99-06 2500HD with a 6.0L in it. Im on rockauto and some of these pressure hoses say for a 99-04. Seems kind of odd cause I don't think they changed anything. Any thoughts?

Alright I think I definently figured it out this time, although I may become confused again haha...

 

I looked up a P/S pump and steering gear for my truck on the ACDelco website and see which other vehicle had both of those equipped from the factory, which turned out to be the same year truck as mine but a 1500HD. So then I looked up a new P/S pump under the 1500HD and there it was, the hydroboost P/S pump. Then found the same gearbox, so then I looked for the hydroboost hoses from hydroboost to gearbox and also from P/S pump to hydroboost, because the pump is the same, just with that extra inlet for fluid from the hydroboost. All in all, I may have been looking all over the internet for hours on end for no reason doing cross reference searching and all that schenanigans

 

Now the only thing I need to find is a cap for the vacuum booster line. It is a quick disconnect there on the back of the motor. Bet I could just find a regular quick disconnect cap at the local hardware store

I just was dealing with some brake issues.. the 05 sierra HD has cross drilled and slotted rotors all around and I changed the front pads, the inside pads were almost at the rivets and the outer pads were 1/4" + left.. I know the inner ones normally were more because of the piston pushing them but this was more then it should have been. So I was debating on getting new calipers just not sure what you guys are using. I looked at wagner and cardone is there any other good brands or upgrades or performance calipers.. OR can I use the 3500 calipers or are the the same?

After the new font brake job it still didn't stop a lot better, so today I took the rear wheels off and the pass side rear inner rotor was destroyed... the inner pad was GONE! and the inside of the rotor was wore away to about 1/8" and the outside pad was 1/4" left. Im going to replace the rear rotors and calipers Im just curious about some upgrades like you guys were talking about.. What is the real difference between the 2500hd brakes and the 3500 brakesm I know there are different brake nums/codes in the inside of the dash..are the calipers bigger or stronger? Or the rotors bigger?

Please let me know guys I want to get this resolved and the truck to stop good. Im debating on braided lines also.

Our trucks are 1500's but I'm sure you could do a google search for "budget brake upgrade for 05 sierra 3500" or whichever truck you were wondering what to do. Im sure there is something out there because GM makes modifying our trucks easy with even OEM parts :D

 

Im going to guess the 3500HD brakes are a little beefier than a 2500HD just because it is rated to tow more, so it needs more stopping power. I would do your research before purchasing anything. And as for brands, go with something that is semi loaded and get EBC brake pads and rotors. Haven't done my brake upgrade yet because now I'm purchasing hydroboost parts. Each brand of caliper Im sure has its pros and cons. If you want OEM quality then buy brand new calipers and brackets and that kind of stuff.

 

And I also bought braided lines, just because a brake upgrade is as strong as the weakest link. I heard from some that braided lines dont help, but there are also a lot of others that recommend them. Guess it depends on how you use your truck

 

P.S: dont forget that with most of the brake upgrades, they require a bigger wheel to fit everything in. I just so happened to have 17's on my truck already, which is the smallest wheel I can have for my brake upgrade.

Hey Chris, do you think this brake upgrade will affect the sticky weights I have on the inside of my wheels? Or will they have clearance?

Just ordered all the parts I need for hydroboost. Got the two pressure hoses, return hose, hydroboost unit, new HD P/S pump, brake pedal, and new master cylinder.

 

I do need the vacuum cap/plug. Anyone know what the part number is for that? I know it is a 1/2" plug, just can't find it on any parts diagram

      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

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      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.
