Engine
Liquid-cooled gasoline, 5-cylinder, in-line engine. Aluminum alloy cylinder block with castiron cylinder liners cast
directly into the block. Aluminum alloy cylinder head with double overhead camshafts and separate intake and outlet
channels.
Engine lubrication is provided by an eccentric pump driven from the crankshaft. Fullflow type oil filter. Exhaust
emission control is accomplished by multiport fuel injection, heated oxygen sensor(s) and threeway catalytic converter.
Charge air cooler (Intercooler)
Turbocharged engines employ a turbocompressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold by approx. 8.7
psi (over atmospheric pressure) and engine power output by approx. 50 horsepower over that developed by the
normallyaspirated engine. The charge air cooler (which resembles a radiator) is located between the turbocompressor
and inlet manifold.Designation: Volvo B 5234 T3

A driver has a responsibility to do everything possible to ensure his or her own safety and the safety of passengers in
the vehicle and others sharing the roadway. Avoiding distractions is part of that responsibility.
The following should be checked regularly: *
1 Washer fluid reservoir should be filled with water and solvent (wintertime: windshield washer anti-freeze). See
page 123.
2 Coolant level should be between the expansion tank marks. Mixture: 50% anti-freeze and 50% water. See page 124.
3 Power steering - When cold, the level must not be above the COLD mark and when hot it must not be above the
HOT mark. Top up if the level drops to the ADD mark with ATF fluid. See page 122.
4 Engine oil level should be between the dipstick marks. The distance between the marks represents approx. 1.6 US
qts
(1.5 liters). See page 120.
5 Brake fluid - check, without removing the cap, that the level is above the MIN mark. Use brake fluid DOT 4+. See
page 122.
* Engine oil should be checked each time the car is refuelled.
Octane rating, see page 64.
