The 5.3 in my 2003 Yukon locked up last week. Oil Pressure went to zero, buzzer went ding, and motor shut off a minute later. No noises or knocks, just shut off. Starter will not turn motor, so I'm guessing it locked up. (320K miles, can't complain)
I picked up a lower mileage (120K) motor to swap in, if it lasts a year or so I'll be happy.
Planning on attacking the swap this weekend. I've done many engine transplants over the years, but never an LS motor.
My question is, do all the accessories need to come off the motor, or can it be pulled complete (like the factory installed it).
I think it'd be easier to swap out the Alt, PS Pump, AC compressor when on the engine stand.
Can the harness be disconnected from the truck, and leave wiring on the motor?
I've watched videos of folks removing the intake manifold when pulling the motor, is this necessary?
Would like to leave it as complete as possible.
Thanks, any input appreciated.
