Does anybody know the complexity in changing out the 02 sensor on this pickup? Are there any special tools required?

Thank you for your input

You need like a 7/8 or 15/16 wrench, or even a crescent wrench will do, that's what I used. Put the wrench on the sensor and turn it out. There is a plug on the other end, so unplug it. Put the new one in it's place. It's so easy.

There are two o2 sensors, about$60 each. I'd replace both at the same time...they aren't that hard to do.
Does anyone know where I can find the Coolant Sensor? Sometimes a faulty coolant sensor will send a bad code like O2 sensor and will cause rough idle. THe closed loop system will not close after engine is warm. I have a 99 1500 4x4 with 360 V8
