2002 Yukon Knock Sensors

I am about to change the knock sensors under the intake manifold on my wife's 2002 Yukon 5.3L. I was wonder if anyone can tell me what gaskets I will need other than the intake manifold gasket?

The knock sensor is located on the side of the block. Are you talking about another sensor? Please be a little more discriptive when asking for help, because it give us the chance to understand and help you better. not only that it keeps you from having to replace something that doesn't need replacing. Thank you and here is the diagram for 4.8, 5.3, 6.0 knock sensor mounting.

The knock sensors on the 2002 5.3L and earlier models are both located under the intake manifold. There is another post in this section with pictures of the knock sensors in the same location as mine the post is "P0332 Knock Sensor 2002 Sierra..help !". I just was just wanting to get the gaskets that I will need ahead of time. I know I will need the intake manifold gaskets but not sure what others I will need, if any. I know that the knock sensors are bad. The knock sensors in this location are known to go bad due to corrosion of the connections and wiring harness.

Well I did some more searching on here and amazingly I have found the info. I searched by P0332 and found this post "6.0 L V8 Knock Sensor Issue, 2003 GMC 2500 -- 416,280 Miles & Still Going Strong" there are pictures and a procedure attached. Thanks to all who contributed.
