Vehicle Damage Warnings



FUEL SYSTEMS

1. Do not operate the fuel pump without fuel.
2. On fuel injected models do not depress the accelerator pedal while trying to start the car.
3. Handle all fuel injection related parts with care as they may easily be damaged.
4. Always use new gaskets or O-rings when installing fuel lines or injectors.
5. Lightly lubricate O-rings and flare connections with gasoline. Do not use engine oil, gear lubricant or brake fluid.
6. After servicing fuel system, check for leaks and correct as needed.
7. Plug all open lines while servicing the fuel system to prevent dust and dirt from getting in.


ENGINE AND EXHAUST

1. 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.
2. Do not use silicone based products on an oxygen sensor equipped vehicle to avoid damaging the sensor.
3. When performing a compression test, remove the fuel pump relay fuse (fuel injected vehicles), and disconnect power to the ignition coil. This will prevent the engine from starting during test (allowing the engine to run with one or more spark plugs removed can cause damage to the catalytic converter).
