Ok, in the past 2 weeks, my truck has been giving me a hard time.
The fuel pump went, so I had to be towed off the parkway, then after routine maintenance, I'm up to about $900.
Yesterday, the engine light comes on, and I get code P0138, so I went to Autobarn and picked up a new O2 sensor.
This time, I'm doing the work myself- Can't afford to give any more money to the mechanic.

I've located the location of the sensor...thanks to the Hayes manual.
I'm trying to break it loose, with out breaking it!

I ran the truck for a bit to make the exhaust system a bit warm. The darn sensor won't budge.
Is it safe to spray on some liquid wrench or something to help free it? Does it normally take some "gentle" persuasion at the end of the wrench with a hammer? Is there any special tool for the job, besides an open ended wrench?

I'm just an oil-change type of guy, but now I'm determined to save money!

Thanks!
ps, this is a 2000 Dakota 4x4 V6 3.9L

 

stick your wrench on it put a pipe on the wrench to make it longer put your foot up on the frame and pull with all your might because they are a B*TCH to take out but make sure you take out the right one lol my front one went out and i accidently took out the back one one time lol
