I have a 95 civic dx auto, and ran into some heating issues about a month ago with a leaky radiator and boiling fluid. Turns out that my radiator fan does not turn on as well. The motor is fine, the fuses are new, and the electric wiring doesn't seem to have any problems.

I already replaced the radiator, but it still overheats. Is the overheating due to the fan not working, or something else?
