Engine Cylinder Head Bolt Set, Victor Reinz (Discontinued)

engine cylinder head bolt set using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with tty (torque-to yield) head bolts, replacement is an absolute necessity. Tty bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used. aplication summary: volvo - 1990-93 240 l4 2.3l, 1976-84 242 l4 2.1l, 1981-84 242 l4 2.3l, 1976-85 244 l4 2.1l, 1981-89 244 l4 2.3l, 1976-85 245 l4 2.1l, 1981-89 245 l4 2.3l, 1980-81 264 l4 2.1l, 1985-92 740 l4 2.3l, 1985 745 l4 2.3l, 1984-90 760 l4 2.3l, 1989-91 780 l4 2.3l, 1991-95 940 l4 2.3l, 1984 dl l4 2.1l, 1984 gle l4 2.3l
