CYLINDER BLOCK - CORE PLUG REPLACEMENT - 2.5L

Note. Cylinder block core plug shown in figure, cylinder head core plug similar.

Scheme 7

1. Use a slide hammer or tools suitable to remove the cylinder block core plug.
2. Inspect the cylinder block plug bore for any damage that would interfere with the correct sealing of the plug. If the cylinder block plug bore is damaged, bore for the next oversize plug. NOTE: Oversize plugs are identified by the OS stamped in the flat located on the cup side of the plug.

Scheme 8

1. Coat the cup-type core plug and bore lightly with sealant and install the core plug. Use a suitable tool to seat the cup-type core plug. CAUTION: Use care during this procedure so as not to disturb or distort the cup sealing surface. CAUTION: When installed, the flanged edge must be below the chamfered edge of the bore to effectively seal the bore.

Scheme 9

1. Coat the expansion-type core plug and bore lightly with sealant and install the core plug. Use a suitable tool to seat the expansion-type core plug. CAUTION: Do not contact the crown when installing an expansion-type cylinder block core plug. This could expand the plug before seating and result in leakage.

Scheme 10
