Clamp the cylinder head firmly back onto the block with the APEX Automobile Parts Inc Cylinder Head Bolt Set, part number AHB1108. It is a direct-fit replacement for the listed applications powered by the L4-2.4L engine. These include the 1995-2006 Dodge Stratus, 2001-2010 Chrysler PT Cruiser, 2002-2005 Jeep Liberty and 2003-2006 Jeep Wrangler.
Head bolts supply the clamping force that holds the cylinder head against the engine block. That force keeps the head gasket compressed so it can seal between the two. Fitting new head bolts is a common step when the head comes off for a head gasket or cylinder head repair.
Signs head bolts may need replacing: a bolt with damaged threads, a bolt that is stretched or corroded, or a head gasket or cylinder head job whose service procedure calls for new bolts.
Follow the vehicle's service information for the tightening sequence and torque. It also tells you whether the original bolts may be reused.
