S10/T10 Blazer 4WD V6-173 2.8L VIN B 2-bbl (1983)
Some 1982-1984 S/T Trucks that were produced with the circular plastic fan blade assembly as shown in Figure No. 1, may experience a "snapping" or
"cracking" type noise from the fan assembly during engine acceleration. If this condition is encountered, the fan blade assembly must be replaced with
the type shown in Figures No. 2, No. 3 and No. 4.
Use the following chart to determine which replacement parts are required. Fan replacement procedures are listed in section 6B of the Light Duty Service
manual.
CAUTION:
Do not stand in line with any rotating fan assembly while the engine is in operation.
Do not use or repair a damaged fan assembly. An unbalanced fan may fly apart and cause personal injury and/or property damage.
Replace any damaged fan assemblies with new assemblies.
