what years gm suv dont have dod or afm?

I think I’d like a large SUV. I believe the 05 &06 escalade came w/ LQ9 w/ electric cooling fans 345HP 379FT LBs
did other large SUV of this era have the LQ9


I do know how to physically identify the dod, valley cover w/ all the bumps.

I do know how to physically identify the afm, large bump on upper timing chain cover.



1.I’d like to know on paper which SUVs don’t have these problematic dod/afm so I can rule them out of my search?

I’ve read that no 2500+ trucks ever had the dod or afm however I want a SUV not a truck.

2.Not sure if the escalade is a 2500?

Additionally open to suburban/tahoe/Yukon.

3.These vehicles have AWD do they have the front half shafts going though the engine oil pan?

4.Hummer H2 is full time 4wheel drive do they have the front half shafts going though the engine oil pan?

5.Lastly doe’s the 07Hummer H2 have dod/afm?
6.can 05&06 electric cooling fan easely be used on 07 Hummer H2

Comment I did search this title came up w/ how to delete dod/afm

Thanks for any advice

 

No Gen III ever had DOD/AFM. So that includes to all GMT 800 trucks and SUVs. The electric fans were only offered on the 1500s. Same on the LQ9.

No E fans, on 2500s. I know that applies to GMT 800s and I "think" on GMT 900s.

The Gen IV 2500 vehicles (so 2007+) did not DOD/AFM, but they do have VVT.

2500 is anything with 8 lugs. The Express Vans are also kinda unique, but I know you already own an RV van.

 

 

OK so for me never buy a newer than 06 to avoid the DOD/AFM I think I'd would also like to avoid VVT.
are the escalades and tahoes ect.1500s
.Hummer H2 is full time 4wheel drive do they have the front half shafts going though the engine oil pan?

5.Lastly doe’s the 07Hummer H2 have dod/afm I think it has the LQ4?
6.can 05&06 electric cooling fan easely be used on 07 Hummer H2 I've heard on ytube the computer can be repinned to use the AC pins to control the E-fans but didn't explain how it's done.

I guess @arthursc2 is your guy on the Hummer. I don't know much about them.

No, none of these trucks have the front axle through the oil pan. The front axle is below/a little in front of the oil pan sump. The front axle is a separate assembly.

Oh, I thought you wanted to avoid electronic fans? You can add them on those later years, but the HDs didn't have them because the mechanical fans are more reliable for heavy hauling/towing.

I guess I should've been more complete about the lack DOD/AFM, that also implied that they didn't have VVT. This is in the GMT 800s.

And aren't you going to ask about transmissions?

 

Let me be very clear with what I am about to say, everything in the following post is concerning 100% factory stock vehicles, no modifications

99-06= NO DoD/AFM

The bump on the timing cover in your first post is for VVT, not AFM. AFM and DoD are THE SAME feature, different names

Tahoe's and Escalade's are always 1500 trucks. LQ9's ONLY came in AWD 1500 class trucks sold as Escalade's, Denali SUVs and Denali pickups

2500 trucks and SUVs are going to be LQ4 powered if 6.0. 2500's are available in the Suburban, Avalanche, Silverado, Sierra, Vans and the H2 is considered a light duty 2500

03-07 H2 = NO AFM/DoD. The ECU is a P59, the engines are gen3 LQ4's. 05-06 efans WILL NOT bolt in. You can add provisions, but the mounting locations are not present for efans to bolt in (SOURCE: just measured my efan swapped '02 Tahoe and my STOCK '07 H2)

Final note NONE OF THE FULL SIZE TRUCKS HAVE THE OIL PAN INTEGRATED FRONT DIFFERENTIAL. That was a midsize SUV thing ONLY. EVERY full-size GM truck has a separate oil pan and front diff, with half shafts OUTSIDE the oil pan. This INCLUDES EVERY YEAR of the Tahoe, Suburban, Suburban 2500, Escalade, Escalade EXT, Escalade ESV, Hummer H2, Avalanche, Avalanche 2500, ALL Silverado's, ALL Sierra's, Yukon, Yukon Denali, Yukon XL 2500, Yukon XL, Yukon XL Denali, Yukon XL Denali 2500

Final note, I have an '07 H2 for sale. 114k, $20k takes her home

Any questions?

 

just a couple clarifying notes to what all's mentioned above:
- 1500HD had eight lug axles
- LQ9 was also in 05-06 Vortec HO (Max) 1500s
- 02-04 Denalis only used LQ4s (to entice people to surge on an Escalade)
- adding "apostrophe s" to a word does not pluralize; it only indicates possession of something else or shortening of the subsequent word, ("is, has, was", etc.)

 

I thought the VVT cam was part of the spring loaded lifters found in dod/afm. so dod/afm are the same vvt is another differnt problem on it's own?
no no I like electric fans frees up some power. as for transmissions GM puts a 4L60 in a 2900LB S10 Overkill then puts it in a 6400 hummer H2 just to weak maybe thats why H2s tow rating is so low.

excellent infor/explanations.
can I tell a Suburban 2500 from a regular suburban from just looking at it, or look at the gvw on door lable. or is the Suburban 2500 have a 2500 emblem on door?
makes sense easy to remember the upscaled suvs w/ awd have the preferred stronger LQ9 engine probally bc it's powering the front wheels an rear wheels.

since the Escalades are AWD can there transfer case's be electronically shifted to neutral and be dingy towed like you'r H2?
I've been considering a H2.
I always thought the H2 was a cool SUV, didn't realize they get like 8MPG, an wear out front end parts unusalley quickly (just something I read not sure if it's true or false).
I could live w/ all the cheap plastic in the H2 like door panels, shift handles ect.
could reseal the silly yellow roof lights but how to know if they've been leaking an allready destroyed underdash electronics an door electronics.

apparently H2 are appreciating.to bad GM didn't offer them w/ the LBZ an big trans.lifting the body off the frame for a swap would be way to much for me in my driveway.

I read on the net that you can drive the H2 70mph over a speed bump an not even notice it is this true or false

anyway I'm wanting a large SUV w/ out the new improved nonesense so I'm aiming for the 05-06 thanks for excellent advice
edit:
I've sean on ytube a class action lawsuit against GM for defective DOD wonder how far back in year models apply.my 07 saab97x has the lifter problem

 

DOD, AFM, and VVT can all be removed. NBS / 99-06 never had em, but the NNBS did. You can remove all of it, if you might still want an NNBS, just in case you want an aluminum 6.2 out of the box.

2500 suburbans would have 8 lug axles.

Escalades came in RWD and AWD. They also came with a 5.3 or 6.0, so don' t assume 6.0.
5th digit of VIN is either C for 2wd or K for 4wd/awd.
8th digit of VIN is engine N is 6.0 on escalade, (U is 6.0 on 2500), and T is 5.3.


Yes you can swap transfer cases on the escalade.

9-7x is midsize, same as the TBSS body, colorado platform, and the H3. Is that on your list?

An H3 (midsize) weighs about as much as a tahoe. An H2 weights almost 1,000 lbs more than an escalade. They have their place, but is that what you want?

 

Then there's those ultra rare 2500 Avalanches with 8 lugs...☺️
