Important Installation Notes:

• This system was designed to fit on engines equipped with a “long” water pump.
and OEM V-belt drives or serpentine accessory dr ives (OEM TPI/TBI) applica­tions, 1990-1995 and GM Perfor mance Parts accessor y drive system #’s
12497697, 12497698 and 12497869). For correct belt alignment, the proper
accessory drive crank pulley and accessory bracketry must be used.These
components are not supplied in this kit. Earlier models equipped with short
water pumps will require a long water pump to be installed.
