These camshafts may be reused. These camshafts and the rocker arms corresponding to the worn lobes must be replaced. Note: If there is any measurable wear, such as shown in Fig. W Fig. Page 8. Page TSI 8. The tools can be ordered from Volvo. Please use the specified part number when ordering. If you are not properly trained and certified in this procedure, ask your supervisor for training before you perform it.
Dirt particles in the fuel and oil channels can cause the unit injectors to malfunction, and can cause the VEB if equipped to fail. Special tools: , , , , J Removal 1 T Fig. Make sure all lifting devices such as chains, hooks, or slings are in good condition and are of the correct capacity. Make sure hooks are positioned correctly. Keep the radiator including charge air cooler and the frontal area free from bugs, dirt, leaves, etc.
Always keep the coolant level above the min. Inspection of the whole cooling system is important. Check for swollen or deteriorated heater and radiator hoses, loose hose clamps and connections, and radiator leaks. Do not work near the fan with the engine running.
Before turning on the ignition, be sure that no one is near the fan. A well functioning and maintained cooling system is as important to the engine as performing regular oil changes or using good fuel. To get the best result it is very important to use quality products and to service the system at the right intervals. Please read this section carefully.
Never add coolant to a hot or overheated engine. Engine damage can result. Coolant consists of clean water and antifreeze. Mix the antifreeze and water to the required concentration before adding to the cooling system. Do not mix different products, such as regular antifreeze and extended life antifreeze. Coolant, consisting of an antifreeze solution in water, should be used year-round to provide freeze and boil-over protection as well as providing a stable environment for seals and hoses.
The solution needs to be tested for proper additive levels at regular intervals see page 45 for testing SCA levels , unless extended life antifreeze is used. Adjust additive concentration if not at the proper levels. Do not use antifreeze formulated for automobile gasoline engines. These have a very high silicate content that will clog the radiator and leave unwanted deposits in the engine.
The main purpose of coolant is to transport heat from the hot parts of the engine to the radiator and to protect the cooling system from corrosion. If you are not sure of the quality of the water in your area, contact your Volvo Truck dealer, your local water department, agricultural agent or an independent laboratory to analyze the water. Additives are part of most antifreeze and should be tested for and added to all coolant mixtures using normal antifreeze. If extended life coolant is used, the additives are in the product when mixed.
Both types need to have additives added to after a time. Additives help prevent rust, scale and mineral deposits from forming. Additives also protect metals from corrosion, prevent water pump and cylinder liner cavitation and contain anti-foaming agents.
Additives are depleted during normal engine operation and need to be replaced. For normal coolant mixture, this means the addition of Supplemental Coolant Additives SCA at any time the additive goes below the recommended level. For extended life coolant mixture, this means an extender package added halfway through the coolant lifetime.
Nitrites or nitrite and molybdate additives protect the cylinder liner from cavitation erosion. Other coolant additives also deplete and need replacement. A too low concentration of additives in the coolant will not provide the protection required by the cooling system. A too high concentration of additives in the coolant can cause additives to solidify and drop out of the solution, depositing inside the cooling system or form a gel in the radiator.
Deposits can be in the form of sludge and scale. Deposits accumulate on hot engine surfaces, reducing the effectiveness of the cooling system or causing water pump leaks. Antifreeze additives not only protect the cooling system from freezing but also against corrosion and cylinder liner pitting. Antifreeze typically comes in one of two glycol types, ethylene or propylene. Propylene antifreeze is NOT recommended for use in a Volvo engine. There is also regular and extended life antifreeze.
If the vehicle is delivered with extended life coolant, there is a label attached to the surge tank. Do not mix regular and extended life antifreeze. Do not use extended life antifreeze unless it is of a type approved by the engine manufacturer. Regardless of the type and make, acceptable antifreeze or premixed coolant must meet or exceed the standards ASTM D and ASTM D , and be formulated for heavy duty diesel engines.
Correctly inhibited to meet the ASTM D standard, it can be regarded as a new coolant which is fully accepted. Antifreeze or premixed coolant meeting the standards ASTM D or ASTM D are primarily for automotive gasoline engines, containing high levels of silicate, and are unacceptable for heavy duty diesel engines. Recommended antifreeze meeting the ASTM D standard is a low silicate ethylene glycol based antifreeze for heavy duty diesel engines.
Extended life antifreeze does not need an initial charge. The following table gives approximate freezing protection for certain mixtures. To increase the antifreeze content beyond that will only decrease the freeze protection.
Coolant SCA level must be tested at least twice per year or whenever coolant loss occurs. The SCA level must be between 1. If the SCA level tests above 3. When testing indicates that the SCA level has dropped below 1. Coolant SCA level must be tested at least twice per year and whenever coolant loss occurs. Depending on the make of antifreeze or premixed coolant, SCAs are added or have to be added to the system after replacement. Run the engine to operating temperature.
After the engine has reached operating temperature, move the heater controls on dash and in sleeper to full heat and run the engine for 10 more minutes. Shut off the engine and allow it to cool. Test the coolant with the test kit. Depending on the concentration of SCA in the coolant:. See example. SCA levels deplete during normal operation and when coolant is added because of low coolant level. SCA levels should be maintained at the middle of the recommended interval.

General Information Oil Sampling The following types of labels are used throughout this manual:. Information For the Owner If there are questions on the maintenance and performance of your vehicle, please discuss them with your Volvo Truck dealer. Safety Information 3 Proper Maintenance Procedure.
WARNING Diesel engine exhaust and some of its constituents are known to the state of California to cause cancer, birth defects and other reproductive harm. Starting Aids DO NOT use ether or other combustible starting aids on engines that have a heater element or other heating devices installed in the intake manifold for heating intake air at cold-starts. Electric and Electronic Systems Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operating.
W WARNING Always wear eye protection when working around batteries to prevent the risk of injury due to contact with sulfuric acid or an explosion.
Grounding Practices Proper grounding for vehicle and engine electrical and electronic systems is necessary for proper vehicle and engine performance and reliability.
