Greetings from Mikey at Just Answer!

The knock sensors (2) are located under the intake manifold.

R u sure that is the location because facing the engine to the right under the head in the side of block is what i thought was it ? but the part i got doesn't look like it or the picture you r giving me. the part i have doesn't match your picture or the piece i am looking at.
Yes, I'm sure, the vortec 4.8, 5.3 and 6.0 all have 2 knock sensors under the intake. They have a problem will water getting past the round boots in the picture. So when you get new ones you have to clean the holes and rtv silicone the boots back in place.

Here is a link with pictures that shows the whole job.

I think the 8.1 has the knock on the outside of the block under the exhaust manifold.
What is the eigth digit of your VIN number?

Customer: replied 8 years ago.
1 is the eighth digit
Are you sure? VIN 1 is the diesel. Better post your whole VIN number. Get the VIN off of the truck windshield tab, not the door and write it down.

my bad i thought u wanted the eighth #. The vin is 1GCHK24U82E241817

Well, its definitely a 2002 vortec 6.0 and those knock sensors are definitely under the intake.
