WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator)may start 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 shouldalways be completely switched off (inmode 0, see page 85) 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 touch-ing any components in the engine com-partment. The distributor ignition system operates at very high voltages. Special safety precau-tions must be followed to prevent injury.Always turn the ignition off when:
• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. See page 373 for information on cooling sys- tem capacities.
CAUTION
• If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
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.
Brake fluid
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed.
