The radiator fan on my 806 has seized and is making a horrible noise! It comes on with the air con almost immediately after the compressor. I've disconnected the feed temporarily but would like to replace the fan asap. I've priced a replacement but would like to remove the old before buying the new one so that I can compare in order to be sure it's a perfect match. Anyone got any tips for its removal? Main dealer wants £65 to replace so I guess it's about an hour if you've done it before. Would a ramp be needed for access or can it be done via bonnet? Many thanks.
