VA LUBRICATION & MAINTENANCE 0 - 3 FLUID TYPES (Continued) down to -67.7°C (-90°F). A higher percentage will freeze at a warmer temperature. Also, a higher per- centage of antifreeze can cause the engine to over- heat because specific heat of antifreeze is lower than that of water. DESCRIPTION - ENGINE OIL - DIESEL ENGINES SAE VISCOSITY GRADE CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethyl- ene-glycol. CAUTION: Low viscosity oils must have the proper API quality. The engine manufacturer strongly recommends the use of synthetic engine oils, such as Mobil t 1 SAE 0W-40.
We strongly recommend engine oils that meet the requirements of the API Service Category CI-4 and meet the requirements of Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395. Do not add any materials (other than leak detec- tion dyes) to the engine oil. Engine oil is an engi- neered product and it’s performance may be impaired by supplemental additives. When topping off engine oil, only use oil of the same quality grade and SAE classification. The SAE class (viscosity) should be selected in accordance with the average air temperature for the season of the year.
The temperature limits given for the different SAE classes should be regarded as guidelines which may be exceeded temporarily to avoid excessively frequent engine oil changes. COOLANT SELECTION AND ADDITIVES The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. Only Mopar t Antifreeze/Coolant, 5 Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain to obtain a freeze point of -37°C (-34°F).
If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution. CAUTION: Do not use coolant additives that are claimed to improve engine cooling.
