Sounds like water temperature issue.

Lets start with simple stuff:

- Check radiator Fins for blockage

-make sure Electric fan is working

-fan shroud is not misaligned or broken.

-check coolant level. ( you may not have a leak, but not enough quantity or proper ratio)

After that, it is cooling system: Thermostat, plugged lines, water pump.

After 2 years without use, I suspect some sort of corrosion and blockage or failure of components, like sticking thermostat or water pump that is nearing seizure.
Good luck
