Re: Oxygen Sensors
I wouldn't change the sensors, until the computer tells you to do so. They are too expensive, in my opinion, to replace with preventitive maintence. When one of the sensors go bad, it will not hurt the truck, honestly you probably would never know that the sensor was bad, if the truck didn't tell you. Also, the sensors are easy to get to, nothing has to be moved to get them off. So go ahead and leave them there until they fail.
Does anyone know if these trucks have a timing belt or chain? If it is a belt you may want to change it, some vehicles have a zero tolerence, that if the belts goes while the engine is running, you just bought a new engine....Something to consider.
