just bought an EJ1 with a gsr w/a b16 head. i replaced the clutch. I took the radiator off to do it to have room. after i got everything back together i went to drive it. after driving around for a bit it started to get really hot. so i went to go bleed the coolant. when i loosened the bleeder valve, nothing came out but steam. i took the radiator cap off to see if it would bleed that way. but it didnt work. i went to go replace the thermostat and when i pulled the hose off there was NO coolant in it. it was completly dry. thot it might just have been the thermostat. but no. i have no clue what it could be. altho water pump comes to mind i guess. any ideas please anyone?
