Engine compartment overview

Updated 23/07/2018
The overview shows some service-related components.

Some of the components included in the car's electric drive system are located under the bonnet. Exercise caution in this area and only touch anything that is related to normal maintenance.


Orange-coloured cables must only be handled by qualified personnel.


Several components in the car work with high-voltage current that could be dangerous in the event of incorrect intervention.

  • Do not touch anything that is not clearly described in this owner's manual.
  • Exercise caution when checking/refilling fluids in the engine compartment.
The appearance of the engine compartment may differ depending on engine variant.

  1. Coolant expansion tank
  2. Reservoir for brake fluid (located on the driver's side)
  3. Washer fluid filler pipe 1
  4. Central electrical unit
  5. Air filter
  6. Engine oil filler pipe


Remember that the radiator fan (located at the front of the engine compartment, behind the radiator) may start automatically some after the engine has been switched off.

Always have the engine cleaned by a workshop - an authorised Volvo workshop is recommended. There is a risk of fire if the engine is hot.


The ignition system works at a very high and hazardous voltage. The car's electrical system must always be in ignition position 0 when work is being performed in the engine compartment.

Do not touch the spark plugs or ignition coil when the car's electrical system is in ignition position II or when the engine is hot.

  1. 1 Fill the washer fluid at regular intervals, e.g. when refuelling.
