Fan clutch

[skar19]

does anyone know the difference between the two or if the m30 can be used on the m20 or vice-versa? can it be retrofitted ie. a m20b20 to a m30b28? just curious........ :dunno:

Nope!. Both diameter of fan blade and thickness different. Actually even the nut screw is different size.

Get a Febi fan-clutch. It about MYR 380 ?. You need a good one or risk overheating the engine!.

gurus,

I think this has been discussed before. is it a fan clutch problem if the engine sound is loud with vooming sound? sorry, do know how to describe it. especially after the engine is hot and the car stop for a while, then press on again.
sometimes the sound is not there.
puzzle. thanks for input
