Mod's sorry if this post is in the wrong spot Please move if needed.

 

New to the board here. I did a general search but could not find a solid answer. I am looking at buying a used Tahoe/Yukon Perhaps even the longer version Suburban/Yukon XL, and want to do some homework.

 

Most of the engine information I see. Appears to show these vehicles have one version or another of the 5.7 (350ci). I am not too familiar with the different variations of this engine and would expect much of the code difference is in how the engine is tuned. Is it accurate to presume the various configurations are done for things like; low-end torque, MPG, top end, emissions. etc?

 

My use is going to be as a daily driver aprox 1200-1500 miles per month. 50/50 city/highway mix.

 

I am looking at a 1996-Newer model.

Questions:

What is typical fuel economy on this truck?

( I know this will vary depending on driving habits. I don’t plant to drag race)

How easy is this engine to work on? I like to do my own maintenance so I am interested in thing like oil changes, filter location, air box accessibility, how accessible are the plugs, transfer case checkpoints.

Any model years to shy away from and why?

Any engine to steer clear of and why?

The 96-2006 model year range has a number of design changes. What model years have the big changes to the chassis, suspension system, braking system, transmission, etc.

Any locations on the body that seem to be more prone to rust points.

Any significant reason to go with the Chevy -vs- GMC other than the grill?

Well maintained what is the life expectancy of the drive train?

 

 

I have always loved the look of the mid-to-late 90’s 2-door Tahoe/Yukon but the 4-door would be more friendly to the family so we will see what the hunt produces. I know you Guys that have these seem to hang on to them for a variety of reasons so I assume they must be happy with the truck.

 

What ever information members can provide will be taken with careful consideration. Thank in advance for any time you take to give me the run down on these trucks.

May not hit all your questions but here goes.

 

I have a 02 Yukon XL 5.3L 4.10 gear and am averaging 18.7 MPG. It will get over 20 on hwy only. If I am not mistaken the New body came in 99 along with the 5.3L which is a completley dif engine than the tried and true 5.7L I personally like the 5.3 and maint on this engine is very user friendly. There is a poll in this forum on miles on these trucks. You will see many have over 250K. My brother in law has one with almost 300K and it has been virtually trouble free.

 

If it were me, I would be looking for a 01 up and if you plan to tow at all, I would go for the Yukon XL or Suburban. Wheelbase does contribute to towing stability.

I may not hit on all your ?s but here goes. I've got a 2000 z71 tahoe. It's the mid 90s body style. 2000 was a split year. My body style having the 5.7 vortec in it. The newer ones having the 4.8 or 5.3 in them. I average 14 in strickly city. (only 2 miles to work and store) Any kind of mixed driving I get about 16.5. I've not had it on a highway trip since I got it. I prefer the ride of the bodystyle I have due to not as much body roll and hit has a little more ground clearance. It is very easy to do work on and mods on. I tow an atv trailer with mine and really like it. The 5.7 has more torque at a lower rpm than the 5.3 but the 5.3 has about 35-40 more hp depending on the year of the 5.3 I've had both motors and there are gives and takes with both. I would stay away from a 2 door tahoe for towing because of the stability. I can tell a difference going from a extended cab short bed to a Tahoe. The truck was definately a bit more stable pulling large trailers. hope this helps.

I have a 2002 YukonXL 5.3l with a 3.73.

Mileage all around is about 17mpg.

If you plan on carrying people, go with the XL or Suburban...your passengers will like you for it.

And like previous posts, if you're going to tow, the extra wheel base would be better.

I have a 97 4 door, 4x4 with 3.73 rear end. I get 12 to 13.5 in the city. 16 to

19 on the highway. I tow a 5400 lb trailer and get 8 to 10 mpg towing.

 

I don't do my own maintenance anymore so can't answer questions about that.

But, this series of engines had problems with leaking intake manifold gaskets.

Also has problems with intermittent windshield wiper motor.

 

I now have 97K miles and plan to run another 100K.

      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.

      By Grumpy Bear · Posted

      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.
