325 tourer - head gasket, now viscous coupling!

[Stu_D]

Hi,

I recently bought a 325i 1989 tourer, she boiled up on the way home from the MOT, how i love days like that! anyways, replacing the head! so bought a viscous coupling from ECP, and was surprised to find it came without the fan bit! i'm sure it's a stupid rookie question, but how on earth do i change just the coupling, i've had a look but i'm stumped!

Cheers for any help!

the nut has a reverse thread lock the fan and get something on the nut take the whole unit off swop the fan onto the new viscous and put it back together

just undo the allen headed bolts and the fan falls off the coupling.

I've undone the allen headed bolts, and it's proper stuck on.... no idea how to get it off, don't want to ruin the whole lot, but it's so frustrating!

???? Fan doesn't stick on the coupling - it's plastic attached to alloy.
However much 'white rust' is on the coupling, I can't imagine it's stuck!

hey,

there's no "white rust", but still can't twist it or any thing!! is it literally just a push out or twist, can i hit it with a hammer?

You have the coupling off the car?Taken the 4 bolts out?Pull fan off,bolt onto new coupling.Honest,its that easy!

Just looked at a fan assembly, and I can't see how the two halves can fail to come apart once the four bolts are removed.

Smack the sucker one with a hammer - doesn't matter about breaking the coupling as it's knackered anyway - it will literally fall in 2 pieces very easily, honest.

cheers for the help guys, funny how the simplist things confuse the hell outta me, like you said a tap with a hammer and straight out, new one on, just waiting for my head then we have the fun of getting the bugger running again! been driving a MK2 golf that's screwed while i'm doing this, bring the BM back to life!!
