Hi all I'm new here so this topic may have already been posted.
How involved is swapping the water cooled alternator. I'm quite handy so not afraid to tackle it.
Thanks
Dan

Not that difficult. It's underneath the r/h cylinder head when looking at the engine from the front.

They are water cooled so encased in a housing that is accessed from the front. Usual pipes to remove, plus viscous fan, maybe radiator (which is quite easy) and belts/tensioners. Then you're just about there. 6 bolts and it comes out. Current:

Thanks Zebedee. I've started today. However got stuck at the viscous fan removal. I've ordered a tool for it. Is it worth buying a quality alternator, seeing as it's a to get at ?
Cheers

In other words, under the left hand cylinder head. **

Mark a spot on the bolt positions, as it's easy to bolt it in wrong. Also, take care to add some RTV, on the o ring, as it often leaks. Don't strip a thread, whole lower timing case will be required if you do. It's heavy, don't bash your rad. The fan nut get hit to the right, catch it with a thick gloved hand, so it also doesn't ruin your rad.. it can be fiddly trying to screw the fan back on. Take your time.

It's quite easy , when you have the viscous fan holding tool and spanner ..

Fit a new O ring to the alternator
Buy the best you can afford
Drain the coolant out the rad first
Make sure you bleed it well with the front raised I found best
As already said put it back in the same orientation or your lead won't reach.

Thanks all

job done. Works a treat

@Dd5884,

Think mine may be starting to play up - Which brand alternator did you buy? Cost? How long to remove and refit?

Thx
