when you cross the equator does the ocean currents change direction?

Answer 1

No. By way of example, the South Equatorial current straddles the equator transporting water from East to West across the Pacific.

Some currents do change direction, but it not because they're on different sides of the eqautor.

The link provided by Glen above shows this--don't know why he answered "yes".
