I also had same problem before when using the A/C... but I did not add another radiator, I added a big fan in the 2nd radiator in the bottom radiator which is near the A/C condenser. My problem was solved... also don't use cheap oil or cheap fuel... it is very sensitive. Also try to add a radiator water coolant.

I used to have a Lucida and was advised by an old importer that due to Japan's horrendous traffic jams, the water works get seriously sludged up - hence the reason so many Lucida / Emina blow head gaskets. The cure is simple - completely flush out the entire cooling system (radflush then water), replace the thermostat (if it's overheated - it's buggered) and Bob's yer Uncle :)
