(a) Remove the 4 nuts and fan from the fluid coupling.
(b) Check that the fluid coupling is not damaged and that no
silicon oil leaks.
If necessary, replace the fluid coupling.
3. INSPECT FAN PULLEY BRACKET
(a) Check the turning smoothness of the fan pulley.
If necessary, replace the pulley bracket.
(b) Reinstall the fan to the fluid coupling with the 4 nuts.
