Can a coolant leak cause an O2 sensor to fail?
About three months ago, after an “at home” engine reseal, I had a leaking manifold gasket. During the repair I got some coolant into the cylinders, which I cleared by removing the spark plugs and cranking the engine.
How can I tell if my coolant tank is leaking?
Identifying the Coolant Leak. There are really only three common causes for coolant leaks, although each type of leak has several possibilities, varying in severity.

How often should I replace my Oxygen sensor?
The following parameters may be helpful guideline for when to replace your oxygen sensors: Model years from the mid-1990s to present day, replace O2 sensors every 100,000 miles Model years from the mid-1980s to mid-1990s with heated three- and four-wire sensors, replace O2 sensors every 60,000 to 70,000 miles
