where can i buy a crank pully beside the junk yard?
Your Honda dealer. or online via aftermarket.

i got a engine swap but the temp seems to always be on cold?
What do you have? and is everything plugged in?and what are you useing for a rad?

and do i have to bleed it out after an engine swap?
Would it not make sense to bleed the coolant every time you drain it all?

sounds like your thermostat could be stuck open.
