Same as Solution #2: The coolant temperature sensor looks like a plug (or butterfly plug) that just screws into the lower portion of the radiator (facing engine bay).
All you need to do is to unplug the electrical wire, loosen the existing one, replace quickly with the new one, this way you don't have to drain your coolant again. But do this when your coolant is not hot to touch.

DTC P0125 OBD-II - Insufficient Coolant Temperature For Closed Loop Fuel Control
This means that the engine coolant temperature (ECT) sensor indicates that the engine has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine. You will likely not notice any drivability problems.
A code P0125 may mean that one or more of the following has happened:
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor
DTC P0135 OBD-II - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135. You will likely notice poor fuel economy the illumination of the MIL.
A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness
