ok, first thing i clean off all the coolant that was spilled with a water hose. next fill up the radiator with coolant, i prefer toyota red coolant because when it leaks it drys and turns red. which makes it easier to see a coolant leak. next look for any coolant leaks from the top of the radiator. when the plastic on top gets old it cracks. ive seen so many toyota radiators do this. next, i would pressure test the coolant system. when you apply pressure look for any visual leaks. if it is holding pressure then i would say it might the thermosat.
