1. Do I need to put any lubrication in the inside surface of the
sealing ring on top of the water pump housing?

You can pre-lube it with dishsoap or KY - avoid petrolium based stuff. Same
goes for impeller.
After you run it - the water will wash all away and your final and only lube
will be the water.

2. Do I need to put any gasket-sealant on the gaskets of the water
pump housing?

NO - just make sure all is clean.

Thanks for the explanation. Now, I understand why I don't need to put
any oil to lubricate the sealing ring at the top of the water pump
housing. The idea of water being a lubricant didn't come to my mind
until you point this out. No wonder the instruction manual asks me to
clean all the oil (in addition to cleaning out dirt grease) from the
drive shaft before putting the sealing ring onto the drive shaft. This
makes perfect sense now.

The SELCO repair manual asks me to put a thin coat of multiple-purpose
lubricant on the inside surface of the water pump housing. I guess
this is to ease the initial hand-turning of the impeller to fit inside
the housing and is not intended for long term. In that case, I should
use dish-soap as what you have suggested or put as thin a coat of
multiple-purpose lubricant as possible.

As of not putting sealant on gasket, I guess the extra thickness of the
sealant may leave too much room inside the housing, and that is the
reason why you don't suggest using sealant, right? This also makes
sense to me. I guess I should not put something where it is needed.
Thanks for the info.
