Cylinder Bore

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The cylinder bores should be measured at normal room temperature, 21 °C (70°F).

The cylinder walls should be checked for out-of-round and taper with Tool C119 or equivalent (Fig 1 ) (Refer to SPECIFICATIONS  ). If the cylinder walls are badly scuffed or scored, the cylinder block should be replaced, and new pistons and rings fitted.
