Transmission oil level - checking
Note! The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.
Warning! Take great care when the vehicle is raised, the splashguard under the engine is removed and the engine is running. Watch out for rotating components on the engine and the radiator fan. Be especially careful with your hair and fingers.
Warning! Avoid skin contact with the oil.
Note! Only use transmission oil with Volvo part no.: 116 1540-8 (1-litre), 116 1640-6 (4-litre).
Check
Conditions
The difference between MAX and MIN volume is 0.3 liters. Check the oil temperature in the transmission.
At room temperature (+20 °C) the oil level is near the MIN marking on the "cold area".
At room temperature (+20 °C) and low oil level the oil barely reaches the dipstick.
The "cold range" (+40 °C) is reached after approximately 15 minutes idling in the workshop, while the "hot range" (+80 °C) is reached after approximately 30 minutes highway driving at an air temperature above +15 °C.
Note! Carry out the check at an oil temperature of +80 °C. Select the digital display parameter. Select the parameter for the transmission oil temperature.
Preparing to check the oil level
Position the car on a hoist.
Apply the parking brake.
Apply the foot brake.
Let the engine idle.
Set the gear selector in position P. Move the gear selector through the various gear positions, stopping for approximately 3 seconds in each position.
Return the gear selector to position P. Wait 2 minutes before checking the oil level.
Checking oil level
Allow the engine to idle with the gear selector in position P.
Raise the vehicle. Remove the splashguard from under the engine.
The dipstick must be pushed down completely in the dipstick tube.
Caution! Wipe off the dipstick with a nylon cloth or similar. Do not use a rag which may leave lint or threads.
Low level (topping up)
Top up with oil through the dipstick pipe. Take the temperature into account when topping up with oil.
Check the oil level again. See: Checking oil level.
High level (overfilling)
Warning! The oil may be very hot if the vehicle has just been driven. Avoid skin contact with the transmission oil.
Warning! The transmission must not be operated if the oil level is too high. This can cause increased operating temperatures and oil leakage.
Note! Strict cleanliness is important.
Drain off oil.
Undo the drain plug.
Allow some of the oil to drain out and reinstall the plug. Tighten. See: Tightening torque, B5254T7, AW55-50/51SN, B5254T7, M66 Tightening Torque.
Hint: The oil can also be sucked out through the dipstick pipe using an oil suction syringe with a narrow gauge hose.
Check the oil level again. See: Checking oil level.
