If its overheating, you should probably STOP driving it, Japanese cars HATE getting hot, your head will probably look like a waffle.

let it idle, take off the radiator cap and see if bubbles start coming up, its most likely a blown head, check your temp sensor first.

But jesus christ, stop driving the poor thing until you sort it out.

You may still may have a problem with that in the summer, when you select the cold setting on the heater control; this operates a control valve on the bulkhead. (near the ABS unit on UK models) this shuts off any coolant going into the heater matrix. The coolant is then diverted back around the system from the pipe union at the rear of the head, which is the same as the heater matrix becoming blocked.
