Transmission Type Standard:
5-speed Manual Transmission (M56H).
Transmission Type Optional:
4-speed Automatic Transmission (AW50-42LE).
AWD Option:
All-Wheel Drive (AWD) was available on certain models (e.g., T5-R, R) with the automatic transmission, featuring a viscous coupling.
Automatic Transmission Fluid:
Volvo recommended AW-1 or equivalent (e.g., Dexron III initially, later specs might vary - manual should clarify).
Manual Transmission Fluid:
API GL-4 or GL-5 synthetic gear oil, viscosity grade 75W-90 is common (manual will specify exact type).
Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil type used. Manual will specify.
Timing Belt Replacement:
Crucial: 60,000 miles or 5 years for most 20-valve engines (non-interference on some early 10-valve engines, but still recommended to change). Manual is definitive.
Transmission Fluid Change:
Automatic: every 30,000-50,000 miles. Manual: Check per manual, often longer intervals.
Engine Oil Specification:
API SJ or SL, viscosity 5W-30 or 5W-40 recommended (check manual for precise spec and capacity).
Coolant Specification:
Volvo's green coolant or equivalent (ethylene glycol based, 50/50 mix with distilled water). Capacity approx. 8.5 quarts.
Brake Fluid Specification:
DOT 3 or DOT 4 (check manual for specific type and replacement interval).
Common Wear Items:
PCV system issues (clogging leading to oil leaks), ABS sensors, fuel injectors, ignition coils, suspension bushings, motor mounts, sometimes turbocharger issues on T5 models.
Common Electrical Faults:
Water ingress into electrical components (e.g., ECU), intermittent dash lights, power window/lock failures.
Transmission Quirks:
Automatic transmissions can be prone to overheating and wear if not maintained. Manual transmissions are generally robust but clutch wear is normal.
