Besides the issues with my serpentine belt I also can't get a wrench on the front manifold O2 sensor to replace it. My new O2 fits in a 7/8" wrench nicely (I only have metric to 19mm) but I can't get this big honking wrench into the small space behind the manifold. Any tricks to this one?

Thanks again!

 

Rent the o2 sensor removal tools from Autozone. It will make things easy.

 

Any advice on the serpentine? Maybe I am out of it today but I am just not getting the R&R procedure from the scanned image in the stickies...

 

I had the code for the o2 sensor on ther rear manifold o2 so i replaced. I bought 1 for the front and had the same problem so i left it but thank kevlo i might get back under my car

 

Get a pipe wrench with a 1" dia. 8" long pipe. That should be able to break the 02 sensor bolt.
