Antifreeze

I'd like to know what the optimum antifreeze type is for my 2000
Hyundai Sonata.

I'm especially concerned about this after suffering from
electrolytic corrosion in my last vehicle -- a Ford, with a steel
block and head, a conventional radiator (forgot), and an aluminum
heater core. The heater core job, as with many Fords, was
intricate and costly, and there was always rust in the coolant
when using conventional ethylene glycol (green) antifreeze. I
just don't want to go there again.

A recommended fix for this nasty Ford problem is to connect wires
to the radiator and heater core, to ground them to the engine
block, and/or change the coolant to a better type. What's the
story for Hyundais?

Thanks.

Richard
