If this is impractical, rocker covers should be removed and clean lubricating oil should be poured over the rocker arms. The oil should be the same weight and viscosity as that used in the crankcase. After pre-lubricating, add additional oil to bring the level to the proper mark on the dipstick. See Figure 3. 3. Entrapped air must be purged after filling the cooling system. To do this, allow the engine to warm up with the pressure cap removed.
With the transmission in neutral, increase engine speed above 1,000 rpm and add coolant to the radiator as required. 4. Check to make sure the front of the radiator and air-to-air charge cooler (if equipped) are unblocked and free of debris. Lubrication System Checks Figure 3 Check Lube Oil Level Before Starting The lubricating oil film on the rotating parts and bearings of a new or newly overhauled engine, or one which has been in storage for six months or more, may be insufficient when the engine is started for the first time. For lubricant recommendation, refer to How to Select Lubricating Oil in the HOW-TO SECTION of this guide. NOTICE:
Extended Storage An engine in storage for an extended period of time (over winter, for example) may accumulate water in the oil pan through normal condensation of moisture (always present in the air) on the cold, internal surfaces of the engine. Insufficient lubrication at startup can cause serious damage to engine components. To insure an immediate flow of oil to all bearing surfaces at initial engine startup, the engine lubrication system should be charged with a All information subject to change without notice. 15 DDC-SVC-MAN-0039 Copyright © 2009 DETROIT DIESEL CORPORATION
