Preventive Maintenance ENGINE MAINTENANCE Engine Lubrication Proper engine lubrication depends on ambient temperature and where the vehicle will be operated. Use the recommended oil for the weather conditions outside. NOTE: For engine oil specifications, oil change intervals, engine filter requirements or general engine maintenance procedures, refer to the Engine Operation Manual included with your vehicle or the engine manufacturer’s service manual. Service Intervals • Check engine oil daily. Oil Draining: • Refer to the engine manufacturer's Engine Operation and Maintenance Manual supplied with your vehicle for information about draining and refilling engine oil, engine crankcase capacity, engine oil type, and changing oil filters, etc. Engine Maintenance WARNING! Hot engine oil can be dangerous. You could be seriously burned. Let the engine oil cool down before changing it. • Drain the oil into a container designed for this purpose. • When draining the oil, remove the plug with the proper size wrench and keep as far away as possible. Always keep your forearm parallel to the ground to help prevent hot oil from running down your arm. • The oil filler cap must be secured to avoid oil spill causing a potential fire hazard. Oil Level Check • To check the engine oil level, park the vehicle on level ground and wait 5 minutes after shutting the engine OFF. This allows time for the oil to drain to the oil pan. • Remove the dipstick and wipe it off with a clean, lint-free rag. • Reinsert the dipstick all the way in and pull it out again to check oil level. Correct oil level is between the low (L) and high (H) marks on the dipstick. For further information regarding oil level, see the engine manufacturer's Engine Operation and Maintenance Manual supplied with the vehicle. Medium Duty (R05/09) Y53-6008A – 169 –
