sup..91 Civic Si B16A...i have 2 fans against the radiator in the front of the car..when the swap was performed they rigged the therostat so that the 2 fans run all the time..do i need both of these fans..if not which one is more important then another..theres a smaller one in front of the headers..and a larger one in front of the trans..the smaller one actually prevents me from adding any aftermarket headers cuz the space is so tight..(place racing mounts)..any help would be appreciated...JR
