2001 5.3 liter chevy silverado complete breakdown to install knocks sensor

Hello,

 

My name is Scott. I am a bit confused with the above. I will clear this up for you.

 

While you have the intake off, replace the coolant capillary o rings at each corner of the head. Also do yourself a favor and install the kinock sensor harness also.

 

Scott.
