I could be mis-remembering, but seems like there was a discussion ??12-15 years ago about fan clutches leaving the factory empty (no fluid) on purpose (in the past) which were meant to be filled with silicone fluid before they were installed??
Maybe @cruiserdan would know??
It's a bit confusing. Looking at Rockauto the FCT-017 (AISIN part#) will work for the FJ62 with the 3FE engine, OEM # 16210-61121 (OEM part still available in the US). Looks like this part may also fit other LC's (?2F, 3F, 3FE)) going back to the late 70's (parts gurus chime in).
AISIN #...
Not a parts expert, but AFAIK:
FCT004 is the standard fan clutch for a 93-97 FZJ80 with the 1FZFE engine
FCT017 is for the 91-92 FJ80 with the 3FE engine
