    2003 Suburban EASIEST EFAN Swap Ever!!

    Which fans are better to use on a conversion, the 5/7 blade fans & shroud or the later 7/9 blade fans and shroud? Has anyone run across a thread that details why GM changed the fans from 5/7 blades to 7/9? I've been looking around and can't find the info I thought I'd seen long ago...

    Used gauge cluster programming

    I pick up gauge clusters with the trans temp from 01-06 GM SUVs & Trucks at the local pick your part to sell. Typically with the age of these, the mileage is high, and up over 200k. What sort of equipment is required to be able to adjust mileage to match a buyer's mileage on their cluster...

    2003 Tahoe coolant system leak or head gasket leak?

    Is that in addition to your annual registration for the vehicle, or is that the registration to get your license plate sticker? The name Tax-achusetts does seem fitting after all ;) Who puts these thieves in power? CA where I'm at isn't much better, but this will collapse in on itself at...

    2003 Suburban EASIEST EFAN Swap Ever!!

    Thanks for the replies. I went down the you tube rabbit hole last night researching this conversion. The fans I found are from an 07 Avalanche. I looked back at the pictures I have of it and it is the common 7 & 5 blade fan setup. So I had first thought it was any 07 and newer vehicle but...

    2003 Suburban EASIEST EFAN Swap Ever!!

    Will the NNBS fans from 07-14 bolt up the same as the 05-06 factory fans? Would you happen to know if the plugs are the same for NBS 05-06 fans and 07+ NNBS fans? Asking all this because I just found a clean set of NNBS fans in a pick your part and considering bringing them home and going...

    Rebuiding my front end - upgrades?

    Was the $1200, now $950 quote for labor only? Where are you located? If that is labor only, it seems a tad high, but that could be area dependent. Is there another reliable shop you could get an estimate from?

    Thanks! Learned something new today and I'll be using that in the near future.

    2003 Tahoe coolant system leak or head gasket leak?

    Interesting.....what does that do? Does that sequence of events prevent the engine from starting? Thanks.

    2003 Tahoe coolant system leak or head gasket leak?

    Another one to consider for replacement is the cam position sensor that's right next to the oil pressure sending unit at the rear of the intake manifold. Mostly that is to avoid the potential oil leak from the cam position sensor sealing O-ring. It's unfortunate that GM does not offer the...

    Renamed: 06 Esky LS364/450 Build (New Leather Seat covers)

    In researching the NNBS/TBSS intake manifold swap onto a Gen 3 engine, I seem to remember reading that most of the improvement from making the swap is due to the larger 87mm 4 bolt throttle body which allows more airflow VS the stock 78mm 3 bolt throttle body. I do think there is some improved...

    Engine swap '04 Tahoe 5.3 to 6.0

    Thanks for all the replies above guys. For future reference on engine removal, I meant to post up in the first post that you can in fact remove a long block engine(block, heads, balancer, flexplate) without dropping the front axle, or removing, disassembling the front core support. All other...

    Renamed: 06 Esky LS364/450 Build (New Leather Seat covers)

    What throttle body are you using with the TBSS manifold? Are you going to pick up the X-link so the newer 6 wire throttle body will work with your 8 wire plug Gen 3 Escalade?

    Engine swap '04 Tahoe 5.3 to 6.0

    Steam line poll: What is the consensus on which steam line is better to use, the 4 port from earlier 99-00 vehicles, or the block off plugs in the back of the cylinder heads and the standard '04 front steam line that vents the heads up front? I have both available. Anyone venture a guess...

    Engine swap '04 Tahoe 5.3 to 6.0

    Going thru things today since my buddy wasn't able to help drop the long block in the Tahoe today. I was looking at part of the engine wiring harness and a question came up. Is the engine harness all one piece, including the lower portion that wraps around the oil pan up front and grabs the...

    Engine swap '04 Tahoe 5.3 to 6.0

    They are the same dimensionally from what I see measuring. From what I was told on LS1Tech for some reason, unknown to me, GM used a different flexplate for the 6.0/4L65e vs the 5.3/4L60e configuration. Yes I've seen one of the flat flexplates on the early "iron head" lq4 and the crank...

    Engine Swap Tomorrow

    Thanks. That's a good deal with all that's included. Shoot at only 150k that original lq9 was just getting broken in ;) Sounds like a good deal all around.

    Engine swap '04 Tahoe 5.3 to 6.0

    I figured I'd start an engine swap thread for future reference and for others who want to do the swap in the future. I'm about half way thru the swap process. The old still running well 335k miles 5.3 that leaked oil prodigiously is out, and on a tire and pallet. The 6.0 is on the stand and...

    Engine Swap Tomorrow

    Congratulations on the new power plant. Just wondering, what happened with the original engine that you're replacing it? It sounds like you're having the swap done by a shop? I am in the same boat with a lq9 swap right now, but I didn't find a local shop that wanted the job. I suspect...

    Heater Hose firewall connections -replace, revision, update

    Thanks for all the replies here. I'm not going to re-use the original ones. I looked and the hoses are all date coded 06-03 which corresponds with the build date on the driver's door tag. Pretty impressive that factory hoses and fittings have made it this long. So I picked up GM OEM plastic...

    4l60e trans rebuilder ?

    That appears to be California TransmissionS (plural). The one in Socal is California Transmission. I think they have 3 shops, East LA, Ontario, and San Marcos.
