what coolant passages is he talking about.
the picture is too small i cant see.

i know you have to block off the coolant nipple that comes off the block and is fed into the throttle body right?
but do i have to block anything else off.

 

Yes, follow that coolent line and you will see it plugs into the rear of the Water Pump Housing.

 

alright
so i need to plug 2 coolant holes total right?

first one is the one on the block itself that goes into the throttle body
and
second is the one that goes to the back of the water pump housing?
