WARNING: HOT COOLANT
To avoid scalding from the expulsion of hot coolant, never
remove the cooling system pressure cap while the engine is at
operating temperature. Wear adequate protective clothing (face
shield, rubber gloves, apron, and boots). Remove the cap slowly
to relieve pressure.
3. Add more coolant if necessary. Open the heater valves before adding coolant.
4. Do not close the heater valves until the engine has been running briefly and
the coolant level is again checked and corrected as necessary.
Monitoring the Engine Operation
While the engine is operating, monitor the battery charge indicator light and the oil
pressure. Excessive idling should be avoided.
Monitoring the Battery Charging System
The battery charge indicator light must go out once the engine starts. If the
indicator light comes on while the engine is running, do the following:
1. Shut down the engine.
2. Test the charging system, per OEM guidelines.
WARNING: BATTERY EXPLOSION
To avoid injury from battery explosion when jump starting the
engine, do not attach the cable end to the negative terminal of the
disabled battery.
3. If necessary, visit the nearest authorized dealer to have the alternator voltage
and output checked.
4. Do a load test on the batteries.
5. Replace components as needed.
Monitoring the Oil Pressure
When the engine has reached its normal operating temperature, the engine oil
pressure must not drop below the following values:
• 55 psi (380 kPa) at rated speed
• 14 psi (97 kPa) at idling speed
If oil pressure drops below these values, stop the engine and determine the cause.
