ok I have a 95 civic cx hb just recently dropped in a jdm b18c gsr, got everything running good got rid of all cel codes, i recently noticiced i had a coolant leak on my lower radiator hose. I got a new radiator hose and replaced it. Now my radiator fan is not kicking on and im overheating when i drive, i filled and topped off the radiator fluid. I think i have a big air bubble. How do i get rid of air bubbles. Cooling fan worked fine before i switched the hoses. I think i might need to upgrade radiators soon to cool my gsr off alot better. any help on how to get rid of air bubbles would greatly be apprecieated.
