2.4L Engine

Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009


NOTE
The identification mark on face of upper and intermediate piston rings must point toward top of piston.


CAUTION
Install piston rings in the following order:



Oil ring expander
 
Upper oil ring side rail
 
Lower oil ring side rail
 
No. 2 Intermediate piston ring
 
No. 1 Upper piston ring
 

  1. Install oil ring expander.
  2.  
  3. Install upper side rail first and then the lower side rail. Install the side rails (1) by placing one end between the piston ring groove and the oil ring expander. Hold end firmly and press down the portion to be installed until side rail is in position. Do not use a piston ring expander.
    NOTE
    The compression rings are marked Y1 for the upper compression ring and Y2 for the second compression ring. These markings must face upward.

    Oil ring expander.
     
    Upper oil ring side rail.
     
    Lower oil ring side rail.
     
    No. 2 Intermediate piston ring.
     
    No. 1 Upper piston ring.
     

  2.  
  3. Install oil ring expander.
    NOTE
    Install the side rail (1) by placing one end between the piston ring groove and the oil ring expander. Hold end firmly and press down the portion to be installed until side rail is in position. Do not use a piston ring expander during this step.
