Today at Ugly Truck, we're answering another frequently asked question: "What parts do I need for an LS swap? What parts can I get from a salvage yard?" We're tearing down this 2004 Chevy Tahoe, and salvaging all the pieces and parts we can from it. Here's a list of what we kept:
ENGINE Obviously! This engine has a ton of miles and is missing a couple freeze plugs, so it will go to the machine shop to determine if any of it is savable.
TRANSMISSION This is a 4wd 4L60E, which we don't need. It will also need to be rebuilt due to mileage, so we'll convert it to 2wd then. Stay tuned for that video!
TRANSMISSION COOLER LINES We reuse both ends of the transmission oil cooler lines, both at the trans and the radiator.
WIRING HARNESS We'll need the main harness running from the fuse box to the PCM to the engine and back to the O2 sensors, as well as a few other pieces and connectors.
UNDERHOOD FUSE BOX We'll need the main fuse panel, as well as its base, cover, and lid.
PCM Another obvious one! Plus, the PCM cover, mount, and bracket. And make sure not to loose the rubber seals in the connectors!
MAF SENSOR/AIR INTAKE BOX Whether you plan to use the stock air filter box or not, you'll need the MAF sensor. We also like to keep the intake tube bellow and clamps in case we need them.
DBW ACCELERATOR PEDAL/HARNESS/CONTROLLER We'll definitely need the accelerator pedal and the ETC module on the firewall, and the harness that runs between.
RADIATOR/HOSES This radiator is trash, and we won't reuse these hoses, but they still work great for mock up. Plus, Jerry has a thing for spring clamps.
DEGAS BOTTLE/COOLANT BOTTLE We'll be installing brand new bottles on our next swaps, but this one is pretty clean and could definitely be reused.
POWER STEERING/ALTERNATOR BRACKET We won't reuse this one, but we'll keep it around as a spare for one of our personal trucks. If your donor has hydroboost, hang on the the return line. We'll use it to adapt the original power steering gearbox to the LS pump.
POWER STEERING/TRANS/OIL COOLERS These are optional for a swap, but we'll be installing them on our 6.0 swaps coming up.
AIR CONDITIONING We'll reuse both the high and low side switches, and we'll need the interior controls to tie the AC into the PCM engine controls.
EXHAUST PIPES/O2 SENSORS We like to leave the front O2 senors and unbolt the flange at the manifold, and cut the pipe just in front of the catalytic converter, so that we have plenty to weld to on the new exhaust system. On these swaps, we won't be using the rear O2 sensors.
BATTERY BOX You'll need the battery tray if you decide to keep the battery in the original location. Plus, the trays can be cut into brackets if needed!
ENGINE COVER The most obvious!
VARIOUS FITTINGS/CONNECTORS/CLAMPS When in doubt, keep it! You never know what might come in handy.
