Lang 6-in-1 Fan Clutch Wrench features sizes 22mm, 32mm, 36mm, 40mm, 48mm and 50mm. The convenience of combining 6 of the most commonly used wrench sizes onto one double-end wrench eliminates the guess work of sizing. Offset wrenches provide better hand alignment and a clearer line of sight while improving accessibility in tight fan clutch areas. Square drive cutouts designed for use with a breaker bar for added torque or length.
