    Another coolant leak thread

    Hi all, I have this small coolant leak that is driving me crazy because I can't find it. Some background info: 2004 Tahoe w/ 340k original mileage, all new 6.0 LQ9 installed 2022(maybe 6k miles so far in 2023), new heater hoses & T's, new coolant reservoir, new radiator, newer water pump moved...

    05-06 Escalade Platinum heated/cooled cup holders wiring

    So I stumbled across an Escalade Platinum heated/cooled cup holder in a standard Escalade recently. Has the wiring for this cupholder been unraveled and anyone know what wire is what? I'd like to power it up and test before buying it. It looks like it's had a hard life, so testing it is first...

    '04 Gauge cluster needle calibration & dim DIC vs. gear display

    I've been playing around with different configurations of factory gauge cluster parts for my 04 Tahoe since the lq9 engine swap was completed. First thought was a Denali cluster, but then moved on to 05 Escalade cluster. In order to keep my original Tahoe cluster details(miles, use, etc), I...

    04 Tahoe wiper arm skipping

    With all the rain we've been having in Socal recently, I've noticed that the driver's side wiper isn't doing a good job. At low speeds on the street, both wipers wipe clean, however, at highway speeds, the driver's side wiper is almost 'skipping'(for lack of a better word) across the...

    AC Delco plug wires date coded?

    Are AC Delco spark plug wires date coded anywhere? The ones in my Tahoe are working well, no misfire or anything like that, but I do not know how old they are since I'm not original owner of the vehicle. I've adopted the idea, if it ain't broke, don't fix it. It would be good to know though...

    05-06 Cadillac Escalade Platinum seats retrofit to Tahoe

    So a Caddy Escalade Platinum recently showed up in a local Pick your Part. I've scavenged a few bits and pieces from it already, other sought after parts(door panels, cluster) were already gone by the time I got to it. The heated and cooled seats are still there along with the dash switch to...

    Intake tube differences Silverado v SUV v Model Year

    Recently I noticed there are differences between the factory intake tubes on certain model years and models of GMT800 trucks & SUVs. By intake tube I mean the hard plastic portion between the mass air flow sensor/airbox and the throttle body. It seems like mostly the trucks received a smaller...

    Recognize these headers

    Anyone recognize these headers? There are no mfg identifying names or marks on them. the only #'s on them are 115 on one flange, and the other side has 116 stamped in the flange. They came off an early 00-01 5.3 engine, which had all these exhaust system ports on the manifolds for possibly the...

    Coolant Reservoir Clean Out

    Is there any effective way to clean out the Coolant Reservoir of the brown stains from being 18 years old? I have it out of the Tahoe currently and tried hot water and Simple Green but none of the brown discoloration residue released from the walls of the reservoir? Anyone found an effective...

    Module on negative battery cable, 2006 Yukon

    I've seen these a few times and wondered; "what is this?" It's on the negative battery cable on an 06 Yukon that I harvested the E-fan harness and relay/fuse block from recently. My 04 Tahoe does not have this. Thanks

    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...

    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...

    Heater Hose firewall connections -replace, revision, update

    I have the engine out of my 04 Tahoe currently. It's being replaced with a 6.0 lq9. I seem to have read that the plastic heater hose Q/D's at the firewall tend to be a problem at some point, so I'm thinking about replacing them now. Mine have never leaked or caused any problems but the...

    Looking for a pair of new motor mounts for a 2004. The 3 GM part numbers I'm seeing are 25828247, 15226255, & 15226251 but there could be others that would work in my application. Looking for a gauge cluster needle removal tool, fork thing that I've seen a time or two. Need to do some...

    Rear hatch glass swap to Escalade

    Thinking about swapping to an Escalade 3rd brake light. It appears you have to swap the rear glass hatch complete as the light base is glued to the glass and will not come off without breaking. How does one go about removing the glass hatch assembly from the lift gate? Thanks.

    6.0 Engine Swap, GM Motor mounts 15226255 vs 25828247

    Replacing both motor mounts on an 04 Tahoe that I'm swapping in a 6.0 lq9. Rockauto is showing different GM part #'s for motor mounts for an '05 Cadillac Escalade vs. the '04 Chevy Tahoe. 15226255(Pink) or 25828247 (Red)...not sure what the color mention is about? Are there differences and...

    6 speed Auto conversion

    Has it been done in a GMT800, specifically an 03 and later? I drive a 6 speed Ford F250 for work sometimes and the vast improvement in driveability with the 6 speed over a 4 speed 4L60/4L65 can't be dismissed. Not looking to blaze trail on this, or reinvent the wheel if it's a major...

    A/C Compressors not all the same 00-06?

    I've been looking at replacement A/C compressors and it appears there may be a difference between earlier year model SUVs (maybe 99-02) and later model year SUVs (03-06). Some appear to have two electrical plugs(one on back, and side plug for clutch) and some have only one plug (side plug for...

    02 Cadillac Escalade factory Aspen White rear pillars, appliques

    Recently I saw a white white Escalade on the road. Previously I have only seen pearl white Escalades. So I did some research and apparently in 2002 only, GM offered the Escalade in what is called Aspen White. Has anyone tried matching these up to the common Chevy color Summit White? How...

    Rear Cargo Cover -roller, difference Tahoe v Suburban

    Are the roller type, rear cargo covers different between a Tahoe and Suburban for the 00-06 generation? I recently came across one in an 00-01 Suburban and tried to snap it in place into an 05 Tahoe. It was too wide to get into place in the Tahoe. It appears my assumption that any 00-06...

    Programming mileage in a replacement cluster

    Anyone know what it takes to be able to do it yourself? What sort of tech or device is necessary to do this on a 99-02 or 03-06 cluster? I'm thinking about buying an Escalade cluster but want to be able to program my actual mileage into it before installing it. I am familiar with all the...
