Adding The SCA to The Heavy-Duty Coolant For Maintenance
Heavy-duty antifreeze of all types REQUIRE periodic additions of an SCA. Test the antifreeze periodically for the concentration of SCA. For the interval, refer to the Operation and Maintenance Manual, “Maintenance Interval Schedule” (Maintenance Section). Cooling System Supplemental Coolant Additive (SCA) Test/Add.
Additions of SCA are based on the results of the test. The size of the cooling system determines the amount of SCA that is needed. Use the equation that is in Table 14 to determine the amount of SCA that is required, if necessary:
Certain abbreviations follow the nomenclature of “SAE J754”. Some classifications follow “SAE J183” abbreviations, and some classifications follow the “EMA Recommended Guideline on Diesel Engine Oil”. In addition to Perkins definitions, there are other definitions that will be of assistance in purchasing lubricants. Recommended oil viscosities can be found in this publication, “Fluid Recommendations/Engine Oil” topic (Maintenance Section).

Lubricant Viscosity Recommendations for Direct Injection (DI) Diesel Engines
The correct SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up, and the maximum ambient temperature during engine operation. Refer to illustration 43 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.
Refer to illustration 43 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated. Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.
Perkins 1204E-E44TA Diesel Fuel Requirements
Perkins is not in a position to continuously evaluate and monitor all worldwide distillate diesel fuel specifications that are published by governments and technological societies. The Perkins Specification for Distillate Diesel Fuel provides a known reliable baseline in order to judge the expected performance of distillate diesel fuels that are derived from conventional sources.
Satisfactory engine performance is dependent on the use of a good quality fuel. The use of a good quality fuel will give the following results: long engine life and acceptable exhaust emissions levels. The fuel must meet the minimum requirements that are stated in the table 17.
Engines that are manufactured by Perkins are certified with the fuel that is prescribed by the United States Environmental Protection Agency. Engines that are manufactured by Perkins are certified with the fuel that is prescribed by the European Certification. Perkins does not certify diesel engines on any other fuel.
