Fuel System and Engine Oil Maintenance

Fuel System and Engine Oil Maintenance

Lubrication System

Oil change intervals may vary according to the lubrication oil grade, fuel sulfur content and running conditions. Refer to Oil recommendations. The oil change interval may under certain conditions be increased. To see if the engine complies Volvo Penta oil analysis needs to be performed. Contact your Volvo Penta dealer for further information.

NOTICE! Oil change intervals must never exceed a period of 12 months.

Oil level, checking and topping up

The oil level must be inside the marked area on the dipstick and must be checked daily before the first start.

• Top up with oil via the filler opening; refer to Maintenance, page 45.

• The oil level can be read both when the engine is stationary (the STOP side of the dipstick) and with the engine running (the OPERATING side of the dipstick).Do not fill above the maximum oil level. Only use a recommended grade of oil, please refer to Technical Data, page 74

• The oil level sensor only measures the oil level at the time when the ignition is turned on. In other words, not continually during operation.

IMPORTANT!

Do not fill up above the maximum oil level. Only use a recommended grade of oil, please refer to Technical Data, page 74.

Engine Oil, Change

WARNING!

Hot oil and hot surfaces can cause burns. Oil changes must be done when the Volvo engine is hot.

1 Connect the drain hose to the oil drain pump and check that no leakage can occur.

2 Pump the oil out (or remove the bottom drain plug and drain the oil). Collect all the old oil and old filters, and hand them to a re-cycling station for destruction.

3 Remove the drain hose (or install the bottom drain plug).

4 Fill with engine oil.

For change volume, please refer to Technical Data, page 74.

Oil Filter/By-pass Filter, Change

WARNING!

Hot oil and hot surfaces can cause burns.

1 Clean the oil filter bracket (2).

2 Remove all oil filters with a suitable oil filter extractor (1).

3 Clean the mating surface of the oil filter bracket. Make sure that no pieces of old oil seal are left behind. Carefully clean round the inside of the protective rim (2) on the oil filter bracket.

4 Put a thin layer of engine oil on the seal rings of the new fuel filters.

5 Install the new oil filters. Tighten the filters ¾–1 turn after they touch.

6 Top up with engine oil, start the engine and let it run for 20-30 seconds.

7 Turn off the engine, check the oil level and top up as required.

8 Check sealing round the oil filters.

Fuel System

Fire hazard. When carrying out work on the fuel system make sure the engine is cold. A fuel spill onto a hot surface or an electrical component can cause a fire. Store fuel soaked rags so that they cannot cause fire. Store fuel-soaked rags so that they cannot cause fire.

IMPORTANT:

Always observe the greatest cleanliness during refueling and work on the fuel system. Only use the grades of fuel recommended in the fuel specification.

Draining condensate, fuel system

NOTICE! Put a collection vessel under the fuel filter tocollect the condensate and fuel.

1 Open the drain nipple (1) in the base of the fuel prefilter.

2 Tighten the drain tap (1) when fuel without water starts to run out.

Engine Fuel Filter Replacement

WARNING!

Fire hazard. When carrying out work on the fuel system make sure the Volvo engine is cold. A fuel spill onto a hot surface or an electrical component can cause a fire. Store fuel soaked rags so that they cannot cause fire.

IMPORTANT:

Do not fill the new fuel filter with fuel before assembly. There is a risk that contamination could get into the system and cause malfunctions or damage.

1 Clean round the fuel filter.

2 Remove the filter with a suitable filter remover. Collect any spilled fuel in a collection vessel.

3 Clean the filter mating surface on the filter bracket.

4 Lubricate the seal with diesel fuel and install the new fuel filter. Tighten the fuel filter in accordance with the instructions on the fuel filter.

5 If necessary, vent the fuel system, please refer to Bleeding the Fuel System, page 58.

Fuel Pre-filter, Change

1 Undo the cable from the water trap sensor.

2 Remove the water trap filter from the filter housing. Collect any spilled fuel in a container.

3 Remove the lower part of the water trap from the filter.

4 Clean the lower part of the water trap with a soft rag. Check that the drain hole in the lower part is not blocked.

5 Install a new seal on the lower part and lubricate the seal with diesel fuel. Re-install the lower part of the filter.

6 Lubricate the seal with diesel fuel. Screw the filter onto the filter bracket by hand until the rubber seal just touches the mating surface. Then tighten a further half turn, no more.

7 Connect the cable to the water trap sensor.

8 If necessary, vent the fuel system, please refer to Bleeding the Fuel System, page 58.
