Note
This
system was designed to fit on engines equipped with a “long” water pump. Vortech
includes a 3-groove accessory drive crank pulley (for use with “long” style
water pumps only). If this kit is to be installed on an engine equipped with
a “short” water pump, a custom accessory drive crank pulley and spacer will
be required.
For
engines equipped with power steering, a remote reservoir (GM “type 2”) style
pump will be required as well as an optional Vortech power steering pump bracket
and pulley assembly. Depending on the vehicle, power steering lines may require
fabrication.
