Hi all,

 

I'm new to this forum and I have really enjoyed reading alot of the posts.

 

A little background on me, I have had a '84 Chevy Suburban diesel for the last 6 yrs has over 200K on it now and is still running strong.

 

I just purchased a 2002 GMC Sierra 2wd ext cab w/ 5.3 eng and 3.73. I love the truck. Since I've been doing the diesel thing so long I have not kept up with the things that pertain to gas engines.

 

So my question is what is the best injector cleaner to use in these new engines?

 

Thanks,

Matt

You can use SeaFoam in the tank, I think the can says 1oz/Gal, I'll but in 30oz to a full tank(26Gal) and use the other 2 oz in the lown mower or motorcycle.

 

Or you can find a hose under the hood, like the PCV valve, that has vacume all the time and suck the can directly into the motor. If you go this route you will have to run the throtle(sp) by hand at the motor. If you don't the motor will stall. Let the motor suck about 3/4 of the can in then let go of the gas so the truck dies. Go inside for 30 min., start your truck, you will have to crank it for 10-15 sec for it to start. Go for a drive and really get on it, this will get all the carbon build up out of the motor.

Your truck will smoke to high heaven don't worry about that just make sure there is a breaze. :driving:

Just make sure you don't let the motor die while you are adding the seafoam through the hose, or you can get hydrolock. Also be carefule too, I was doing the treatment on a mustang a couple of weeks ago and i poured it in a little fast and the d**n thing backfired through the throttle body and blew the steam from the seafoam out the vacuum hose I was using. Like an idiot I was holding my thumb over the hose hoping the motor would recover and not die, then it backfired. That burned like S**t.

I know i will get bugged about this, but here goes. I am a parts manager for a GM and Chrysler dealership. I have carried and tried all kinds of "in the fuel tank" fuel injection/system cleaner, but one has always stood out above the rest. If you are just wanting to add something to the tank every now and then, buy the genuine MOPAR injection cleaner. Believe it or not, it really works well, especially when you have a slight rough idle, or fuel type problem. Its not a fix all fuel system cleaner, but just a good....great...all around injection system treatment. I have never used the seafoam stuff the others have talked about, and i am sure it does a great job, but this is just for adding to the tank and helping out dirty injectors. The plus side....its less than 5 bucks a bottle...

THANKS

There have been a couple of posts from GM techs warning everyone NOT to use vacuum hoses and lines to apply Seafoam. If the search thingy isn't on the fritz, look it up. I'm having trouble with it at the moment.

tecron or seafoam, bouth work good. if you have a lot of miles use the seafoam first, then use the tecron about every 3000 mi. i found that putting 2 bottles in at a time works best for me.

I recommend (and use) the Chevron Techron cleaner.Its also the same stuff you can buy at your GM dealer because they make it for them.We sell a lot of it here at the dealership,and it seems to work quite well.

Another vote for Seafoam. It's the only cleaner where I can actually see something happening. When you do it and first start the vehicle up after treatment..... you'll see what I mean. All that black smoke has to be something being burned off.

i have been using lucas fuel injector cleaner for awhile now...does any one else use it?also how do they like it?

 

 

 

I like the techron, I have been using it about every 6 or 7 tanks, but I had a PCM tune a few months ago, which requires 93, but it seems recently the quality of gas has dropped off, so I run the lucas through every other tank to take care of the pinging, good stuff.

I use techron. I did some research on this and unless you have any problems, chevron fuel has a high enough dose of techron in it. If you use Chevron with techron in it, you should never have to add any kind of cleaner or conditioner to your tank. As far as lucas goes, I have never tried the injector cleaner, but I have used the PS pump conditioner and it is great. Read my post on the HD forum. This is ironic because I just posted this morning.

I use the Techron as well, I don't feel comfortable using the Seafoam. Maybe when my vehicle gets 200,000 miles on it I'll give it a shot, thats probably when it will need it anyways.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
