If you read your manual it probably says something to the effect of being compatible with aluminum engines. The old fashioned green coolant will meet this spec.
It should be flushed every couple of years but if you do it yourself it's cheap enough. Under $20 for two gallons and some distilled water to mix with it.

an ethylene-glycol-based coolant to prevent
corrosion and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified

more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
