Knock Sensor - Installation

5.7L





1. Thoroughly clean the knock sensor(s) mounting hole.
2. Install the knock sensor(s) (1) into the cylinder block.

NOTE: Over or under tightening the sensor mounting bolts will affect knock sensors 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. Position the knock sensor(s) (1), install the retaining bolt(s) (2) and tighten to 20 Nm (15 ft. lbs.).
4. Install the electrical connector(s) (5).
