Need step-by-step repair procedures for your 1996-2004 Volvo S40 or V40? This 310-page Volvo S40 service manual PDF walks both models through every system, GDI and non-GDI engines included. You get complete wiring diagrams for starting, charging, fuel injection, central locking, and headlight levelling, plus a full servicing specifications section with torque figures, fluid capacities, and maintenance intervals. Step-by-step engine chapters take you from a compression test and timing belt swap all the way to cylinder head overhaul and crankshaft inspection. Check your valve clearances, verify compression, and refill every fluid to the exact capacity the factory calls for. No more chasing wiring faults with a multimeter and a prayer. Bookmarked with a working text layer: search any spec, jump straight to the section, and get wrenching.

Volvo S40, V40 Common Problems This Manual Covers
Volvo S40 hard starting and rough idle, engine cranks strong but takes several tries to catch
Check battery condition first; a healthy battery rests at 12.6 volts. If cranking is strong, remove the throttle body and clean carbon deposits from the plate and bore, a known fix on these cars. Follow the difficult-starting chart on page 290, then work through fuel system procedures starting on page 99 for non-GDI engines.
Manual Section: Engine Troubleshooting p. 290Knocking or grinding from the front suspension over speed bumps and under acceleration
Jack the front end and check whether the spring coils contact the strut mount, a common fault. Verify both driveshafts are fully seated; a half-seated inner joint knocks on and off the throttle. Drive on full lock below 10 mph and listen for clicking from a worn outer CV joint. Suspension and driveshaft procedures begin on page 133.
Manual Section: Starting, Charging, Ignition, Clutch, Transmission, Driveshafts, Suspension, Steering, Bodywork, and Electrical Systems p. 133Temperature gauge climbs in traffic, coolant level drops with no visible leak
Pressure test the cooling system cold and watch the coolant pump weep hole for seepage. Drop the thermostat in heating water and confirm it opens fully. Check the radiator cap seal while you are there. Refill with a 50 percent antifreeze mixture and bleed thoroughly. Radiator, thermostat, and pump replacement procedures start on page 87.
Manual Section: Cooling, Heating and Ventilation Systems p. 87Oil spots under the engine, wet film of oil across the sump and lower block
Degrease the sump and lower block, run the engine for 15 minutes, then trace the fresh oil track to its highest point before condemning the sump gasket. Check the sump bolts for looseness first; retightening often cures it. Sump removal on GDI engines is covered from page 53, and in-car procedures for other engines start on page 35.
Manual Section: Engine (Gdi) In-Car Repair Procedures p. 53Central locking and electric windows work intermittently, warning lights flicker over bumps
Measure voltage drop across the battery earth strap with the headlights on; anything over 0.5 volts means a corroded connection. Clean and remake the main earth points, then trace each affected circuit against the wiring diagrams starting on page 264. Central locking and electric window repair procedures are covered from page 133.
Manual Section: Wiring Diagrams p. 264Frequently Asked Questions
How do I reset the service reminder indicator on my Volvo S40/V40?
To reset the service reminder indicator, start with the ignition switched off. Press and hold the reset button for the trip meter, then switch on the ignition while keeping the button pressed. If the button is released within 4 seconds, an audible signal will confirm the light has been reset. p. 22
How do I reset the shiftlock override on an automatic transmission Volvo S40/V40?
If the shiftlock system prevents moving the selector lever, you can override it by turning the ignition switch to position II and depressing the shiftlock override button located to the right of the selector lever. p. 157
What is the recommended engine oil capacity for a 1998 Volvo S40/V40 (excluding GDI)?
For 1998 models (excluding GDI engine), the engine oil capacity including the filter is 5.4 litres. p. 16
What is the correct spark plug gap for a 1.6 litre Volvo S40/V40?
The correct spark plug gap for 1.6 litre models is 1.4 mm. p. 16
What is the torque specification for the engine sump drain plug on a non-GDI Volvo S40/V40?
The torque specification for the engine sump drain plug on non-GDI models is 35 Nm (26 lbf ft). p. 16
