95 turbo gsr running a civic half size. its a single core, but its twice as thick as stock. anyway, when i was going to bleed the system the other day, i took the cap off; started the car and waited. the fan came on and all, but i never saw any coolant get sucked in or move. it just sat there. shouldnt i see the coolant moving? oh and the highest i let it get was half way and i turned the heat on and it dropped back to 1/4 of the way.
