Hi Patrick -
I usually recommend replacing coolant once a year, especially in areas where there are severe temperature changes through the seasons.
That said, I would change it now (don't forget to flush it out and replace the thermostat while your at it). Follow the instructions on the dilution ratio on the label. I usually recommend a 50/50 blend of coolant and water.
Too strong of a mixture will leave deposits in your radiator.
Hope this helps -
