I would have it put on an obd2. it might just be an o2 senser.
if you just had something done to the coolant system, could be a possible thermostat sticking open or closed, and other issues with the car such as hesitations or poor engine performance? if not scan tool required
as long as the weep hole is dry under the water pump and it stays within operating temps, it should be fine. also post the codes when u do a scan on the OBD2 computer.
