The radiator light is low coolant. It probably lost coolant somewhere along the line and wasnt refilled correctly or is still losing it. Check for leaks and refill at the thermostat housing to make sure no bubbles exist in the system. Careful if you have the all plastic intake manifold when replacing the thermostat. It will crack if you torque the bolts too much.
The ABS light is probably a bad ABS sensor. Problem is, which one? You can check to see if you have a cracked one and go from there.
