#### TESTING

At the present time there is no known way to reliably test catalytic converter operation in the field.

An infrared HC/CO tester is not sensitive enough to measure the higher tailpipe emissions from a failing converter. Thus, a bad converter may allow enough emissions to escape so that the car is no longer in compliance with Federal or state levels, but will still not cause the needle on a tester to move off zero.

The chemical reactions which occur inside a catalytic converter generate a great deal of heat. Most converter problems can be traced to fuel or ignition system problems which cause unusually high emissions. As a result of the increased intensity of the chemical reactions, the converter literally burns itself up.

A completely failed converter might cause a tester to show a slight reading. as a result, it is occasionally possible to detect one of these.

As long as you avoid severe overheating and the use of leaded fuels it is reasonably safe to assume that the converter is working properly.

NOTE: IF THE CATALYTIC CONVERTER BECOMES BLOCKED, THE ENGINE WILL NOT RUN.

The converter assembly has a "Emission Warranty'' contact your local Datsun/Nissan dealer for more information.
