oxygen sensors and fan blade

[motu]

Are the O2 sensors on a 99 difficult to replace? I notice my fan blades have some cracks, have you had one fail? What other models can I take a fan off of?

Search for my old thread about O2 sensors, rears are easy and passenger front is pretty easy and driver front is tough but much easier if you unbolt brake booster from the firewall.

All 97+ Q45's have cracks in the fand blade and i haven't heard anybody have one fail. Mine has been cracked for 50+K miles and 4 years.

Add the 90-96 Q45 to that list. I've never heard of one fail either except in lore and I've been watching cracked fan blades on my Q's for over 4 years also.
