Installation
5.7L
1. Thoroughly clean knock sensor mounting hole.
2. Install sensor (1) into cylinder block (3).
NOTE: Over or under tightening the sensor mounting bolts will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensors. The torque for the knock sensor bolt is relatively light for an 8 mm bolt (2).
NOTE: Note foam strip on bolt threads. This foam is used only to retain the bolts to sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
3. Install and tighten mounting bolt (2). Tighten to 15 ± 2 ft. lbs. (20 Nm) (176 in. lbs.).
4. Install electrical connector to sensor (5).
