2024 FORD F650/750 oil level

If these modified engine performancecharacteristics persist for an extendedperiod and either the service engine soonor powertrain malfunction, reduced power,electronic throttle control light isilluminated, have the system checked byan authorized dealer.
Service engine soon
Powertrain malfunction, reducedpower, electronic throttle control
Diesel Lubrication System
It is important to change the engine oil atthe recommended service intervals orwhen indicated by the information displayto maintain oil viscosity. Extending the oiland filter change interval beyond therecommended interval can negativelyaffect engine performance, fuel economyand engine life. See Engine Oil Check(page 227).
Engine and secondary cooling system
The cooling system contains a primarycooling loop to cool the engine and asecondary cooling loop to cool thetransmission, charge air, and fuel. Thecoolant serves three primary purposes: toprovide heat transfer, freeze pointprotection, and corrosion protection usingadditives.
Vehicles with diesel engines typically areused to carry heavy loads and accumulatemileage rapidly. These two factors maycause the additives in the coolant to wearout in a shorter time. You can find moreinformation about coolant additives andcoolant change intervals in the coolantchapter. See General MaintenanceInformation (page 325). Operating theengine with insufficient coolant or coolantadditive can cause severe engine damage.
Selective catalytic reduction system
Your vehicle is equipped with a selectivecatalytic reduction system designed toreduce emission levels of nitrogen oxidesfrom the exhaust of your diesel engine. Thissystem relies on the use of Diesel ExhaustFluid (DEF) that you must replenish atcertain intervals. Failure to maintain properDEF levels or if the DEF becomescontaminated will result in vehicle speedlimitations or result in your vehicle enteringan idle-only mode. See SelectiveCatalytic Reductant System (page 120).
Minor Troubleshooting Guide
If the engine won’t crank
WARNING: Battery posts,terminals and related accessoriescontain lead and lead compounds. Washhands after handling.
Turn on the headlights. If the lights are dim,do not go on at all or when the ignition isturned to the start position, the lightsbecome dim or go out, the batteryconnections may be loose or corroded, orthe battery may be discharged. If there isa clicking or stuttering sound coming fromthe engine compartment when you turnthe key to the start position, this may alsoindicate a loose or corroded batteryconnection.
Check the battery connections at thebattery posts, cable connection to theengine grounding point and at the starterconnection.

Engine Oil Pressure Gauge
Indicates engine oil pressure. At normaloperating temperature, the level indicatoris in the normal range. If the pressure gaugefalls below the normal range, stop yourvehicle, switch off the engine and checkthe engine oil level. Add oil if needed. If theoil level is correct, have your vehiclechecked by an authorized dealer.
Engine Coolant TemperatureGauge
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator is in the normal range. If theengine coolant temperature exceeds thenormal range, stop your vehicle as soon aspossible, switch off the engine and let theengine cool.
Fuel Gauge
The fuel gauge indicates about how muchfuel is in the fuel tank.
The arrow adjacent to the fuel pumpsymbol indicates on which side of yourvehicle the fuel filler door is located.
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a slope.
Low Fuel Reminder
A low fuel level reminder displays andsounds when the distance to emptyreaches 50 mi (80 km),25 mi (40 km),10 mi (20 km) and 0 mi (0 km) for allvehicle keys.
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Distance to Empty
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank. Changes in driving pattern cancause the value to not only decrease butalso increase or stay constant for periodsof time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator is in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop your vehicle as soonas possible and verify the airflow is notrestricted by snow or debris blockingairflow through the grille.
Special operating conditions such assnowplowing, towing, or off-road use maycause higher than normal operatingtemperatures. See Special OperatingConditions Scheduled Maintenance(page 335).
To lower the transmission temperatureinto the normal range, alter the severity ofyour driving conditions. Operating thetransmission for extended periods with thegauge in the higher than normal area maycause internal transmission damage. If thegauge continues to show hightemperatures, see an authorized dealer.
