I know that many of you have strong views about using the Haynes manual, but I still like to use it as one of my sources alongside the workshop manual and this forum. The Haynes manual suggests "lubricating the water pump sparingly with grease" as part of the 12,000mile service and contains a section on dismantling the water pump.
You don't need to tell me your views on the Haynes manual

Have fun,
Mikey
