Workshop Manual S3.8 Engine A030K288 (Issue 2) 01-2010 To prevent rush formation and freezing of water inside water jackets of crankcase and cylinder head mix antifreezing agent as recommended. oil filter cartridge change period specified by us. The engine oil should be replace by at every 500 hrs along with the engine oil filter cartridge and "O' ring. Percentage of antifreeze agent in cooling system which depends upon ambient temperature is shown in following table : The oils of two different specification should not be mixed. Do not use recycled oils even for topping up. They have already lost their vital properties.
The adverse effect using reclaimed oil will not be seen immediately, but the life of the components will be greatly reduced. Up to Ambient Heavy Duty Antifreeze temperature 0C Water agent -40 50 50 Recommended Antifreeze Agents It is difficult to recognise a poor quality oil. Therefore, buy the recommended brands in sealed tins only from authorised dealers. Volvoline It is recommended that the entire cooling system should be drained and filled with fresh mixture of antifreeze agent and water in the ratio of 50:50 for ambient temperature of up to -40 C. Coolant should be drained and replenished in the recommended ratio every two years Or 1500 hrs which ever is earlier.
The oil change periods recommended in maintenance schedule should be adhered to. Recommended grades of engine oils confirming to SAE API CF4 and MB 228.1 specifications and grade selected according to range of ambient temperatures are to be as given below : LUBRICANTS Coolant reservoir is to be filled externally, upto ‘L’ level with same coolant concentration. Coolant Please use only recommended brands of oil for getting optimum engine performance and life. There are several brands of lubricating oils in the market. Only some of these oils have been approved by us for use in S-3.8-G engine. The lubricating oils approved by us is volvoline which conform to following specification :
Coolant is recommended to prevent corrosion of engine & radiator and to increase boiling point of water. An ethylene glycol (type JIS K 2234-94, class 2) During initial fill of coolant in the engine 5 liter ethylene glycol is to be mixed with 5 liter of soft water. And the mixture is to be poured in the radiator. Please note that colour of the ethylene glycol supplied along with engine is green. SAE API CF4 Engine Oils The recommended oils have certain vital properties that help to reduce the wear and tear of the components. We have tested these oils for thousands of hours in similar conditions your equipments is likely to encounter.
The optimum period of use for each oil filling has been carefully determined. Therefore, always use only the approved oil. Strictly adhere to the engine oil and 50:50 water to ethylene glycol mixture is to be used for top up. Change Coolant during every D Check. 26
