Engine compartment – overviewThe overview shows the main inspection points in the engine compartment.
Coolant expansion tank

The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition should always be completely switched off (in mode 0,
see Ignition modes (p. 82)) and there should be no remote keys in the passenger compart- ment. The gear selector should be in the P
(park) position. If the engine has been run- ning, wait until it has cooled before touchingany components in the engine compartment. The distributor ignition system operates at very high voltages. Special safety precautionsmust be followed to prevent injury. Alwaysturn the ignition off when:
• Replacing distributor ignition components e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.

Engine compartment – coolant
Normally, the coolant does not need to be changed. If the system must be drained, consulta trained and qualified Volvo service technician.
Level check and filling
Location of the coolant reservoir
See Fuel tank volume – specification and volume (p. 387) for information on cooling systemcapacities.
CAUTION
• If necessary, top up the cooling system with Volvo Genuine Coolant/Antifreezeonly (a 50/50 mix of water and anti-freeze).
• Different types of antifreeze/coolant maynot be mixed.
• If the cooling system is drained, it shouldbe flushed with clean water or premixedanti-freeze before it is refilled with thecorrect mixture of water/anti-freeze.
• The cooling system must always be keptfilled to the correct level, and the level must be between the
MIN and MAX
marks. If it is not kept filled, there can be high local temperatures in the enginewhich could result in damage. Checkcoolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and has alower boiling point. It can also causedamage to the cooling system if it shouldfreeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
• If there is coolant under the vehicle, if youdetect coolant fumes or if it necessary totop up with more than approx. 2 qts (2 lit-ers) of coolant, engine damage could
occur if the vehicle is driven. Have it towed to an authorized Volvo workshop.
WARNING
• Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
