Bolt the head back onto the block with the APEX Cylinder Head Bolt Set, part number AHB350, the fasteners that clamp the cylinder head down and hold the head gasket under compression. It is a direct-fit replacement for the listed Buick, Chevrolet, Oldsmobile, Pontiac and Saturn applications with the V6-3.1L, V6-3.4L and V6-3.5L engines. Among the many vehicles it fits are the 2005-2009 Chevrolet Equinox (V6-3.4L) and 2000-2005 Chevrolet Impala (V6-3.4L).
Head bolts are designed to apply clamping force across the cylinder head so the head gasket can seal between the head and the block. Many service procedures call for new head bolts whenever the cylinder head is removed, such as during head gasket or cylinder head work. Replacement is also called for when a bolt is stretched, damaged or has corroded threads. Consult the vehicle service information for the correct tightening sequence and torque procedure, and for whether any original fasteners may be reused.
See the Buyer's Guide tab for the full list of vehicles and engines.
