Engine And Exhaust

CATALYTIC CONVERTERS
On vehicles equipped with catalytic converters, the following conditions must be observed:

a. Use only "UNLEADED FUEL".
b. Avoid running out of fuel.
c. In case of poor engine operation (misfiring), avoid driving the vehicle and correct the problem as soon as possible.
d. Do not disconnect any spark plug wires with the engine running.
e. Avoid push starting the vehicle.
f. If running on a dynamometer, make sure the catalytic converter is well ventilated.
g. Use caution when working near the catalytic converter to prevent the possibility of burns.

OXYGEN SENSORS AND SILICONE
Do not use silicone based products on an oxygen sensor equipped vehicle to avoid damaging the sensor.

COMPRESSION TESTING
When performing a compression test, disconnect power to the ignition, and remove the fuel pump relay fuse (This will prevent the engine from starting and avoid flooding the engine with gasoline during testing.)
