Under the Hood Inspection
For maximum service life of your truck engine, make a thorough under the hood inspection before starting the engine. Look for such items as oil or coolant leaks, loose bolts, worn belts and trash build-up. Remove trash build-up and have repairs made as needed.Perform required Daily maintenance before starting the engine.
Each time any significant quantity of oil (or other fluid) is spilled on or near the engine it should be cleaned up. Accumulated grease and oil on an engine is a fire hazard. Remove this debris with steam cleaning or high pressure water at PM Level 2 or every 6000 hours.Wipe clean all fittings, caps and plugs before servicing.
Starting the Engine
Do not store starting fluid containers in the cab. Failure to do so, could result in an explosion and/or fire and possible personal injury.If equipped with an electrically or fuel ignited manifold heater, DO NOT use ether.
Startability will be improved at temperatures below +32°F (0°C) by the use of a starting aid (ether) or use of a cylinder block coolant heater or other means to heat the crankcase oil. This will help alleviate white smoke and misfire during cold weather start-up.Use ether when temperatures are below 32°F (0°C) for cold weather starting purposes only.
When using starting fluid, follow the manufacturer's instructions carefully, use it sparingly and spray it ONLY WHILE CRANKING THE ENGINE. Excessive ether can cause piston and ring damage.Use ether for cold starting purposes only.
If the engine fails to start within 30 seconds, release the starter switch and wait two minutes to allow the starter motor to cool before using it again.Start the engine using the following procedure:1. Place the transmission in NEUTRAL and disengage the flywheel clutch (if equipped) to remove the transmission drag and prevent movement of the truck.Depressing the clutch in cold weather can mean the difference between starting and not starting. Depressing the clutch in warm weather produces faster starts and reduces battery drain.2. Turn the ignition switch to the ON position and push the crank button or turn the ignition switch to the START position.3. Crank the engine. If the engine fails to start in 30 seconds, release the starting (ignition) switch and wait two minutes to allow the starter motor to cool before using it again.
Do not increase engine speed until the oil pressure gauge indicates normal. Oil pressure should raise within 15 seconds after the engine starts.If oil pressure is not indicated on gauge within 15 seconds, do not drive the truck. Stop the engine, investigate and correct the cause.
4. Allow the engine to idle three to five minutes, or until the water temperature gauge has begun to rise. Check all gauges during the warm-up period.5. Check fuel level gauge. Do not fill fuel tank to top. Fuel expands as it gets warm and may overflow.Starting With Jumper Cables
When boost starting an engine, follow the instructions to properly start the engine. This engine may be equipped with a 12 or 24 volt starting system. Use only
