Begin by removing the alternator belt. Remove the alternator wiring harness. Remove the alternator retaining bolts. The alternator will come off.
The 2001 model of the Light-Duty Silverado 1500, had an option of four engine sizes; a 6.0L Vortec V8 engine, a 4.3L Vortec V6, a 4.8L Vortec V8 or a 5.3L Vortec V8. The Heavy-Duty 1500HD comes with three engine options, these are 6.0L Vortec V8, 8.1L Vortec V8 and a 6.6L Duramax V8
NO. That would be the TBI / throttle body injection engine Not a vortec. The vortec will not work in the 91.
It's integral to the alternator.
As far as a direct bolt in NO. But if you have the smarts and the know how, you can put anything in there.
No, the LS2 is an all aluminum 6.0 liter engine. The 5.3L engine in the 2000 Silverado is an LM7 version of the Vortec 5300.
A 2000 Silverado 5.3 Vortec that is hard to start and misses on one side of the engine might have a problem with the coil pack or the spark plugs. It could also mean that the block is cracked if the engine is prone to overheating.
The Mass Air Pressure sensor is located at the top rear of the engine, close to the firewall. Remove the Vortec engine cover (I believe it's an 8mm), and from the driver's side, find the rear-most sensor connection (it has 3 wires), and follow it. The sensor looks like this:
A 2000 Chevy Silverado K2500 with 6.0 Vortec engine.
It is inside of the oil pan. You will have to remove the oil pan to get to it.
If you look at your old 1 real good, you will see the amperage stamped into it.
If it has a 350 Vortec engine, then it is on the left bottom side of the timing cover behind the harmonic balancer. If it has the genaration II engine then it is behind the starter. You will need to remove the starter to be able to see it.
The 5.3 liter Vortec Engine on the 2000 Chevy Silverado has a tapered crank shaft. The crank pulley has no woodruff key, is not indexed and is pressed on.
