Engines If the outside temperature is below 60°F (16°C), fully depress the throttle, after engaging the starter. loss of oil pressure, and shut down the engine be- fore damage can occur. 5. Turn on the ignition switch. NOTE: Idle diesel engines about three to four min- utes at 1000 rpm before operating a loaded ve- hicle. CAUTION Don’t crank the engine for more than 30 seconds at a time during any of the following procedures. Wait two minutes after each try to allow the starter to cool. Failure to do so could cause starter damage. Starting After Extended Shutdown or Oil Change Do the following steps after an oil change or after the engine has been shut down for more than three days:
WARNING 1. Disconnect the electrical connector from the fuel pump solenoid valve. Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury or property damage. 2. Crank the engine until oil pressure shows on the gauge. 6. When the engine is started, it takes a while to get the lubricating oil film reestablished between the shafts and bearings, and between the pistons and liners. Bring the engine up to operating speed gradually as it warms up and develops stable oil pressure. 3. Connect the electrical connector to the fuel pump solenoid valve. 4. Start the engine.
After one minute, shut down the engine and check for leaks. 5. Allow five minutes for the oil to settle, then check the engine oil level and add oil if needed. Do not overfill. The oil pressure gauge indicates any drop in lubri- cating oil pressure or mechanical malfunction in the lubricating oil system. The operator should note the 4.2
