Est. Repair Cost: £400–£2,500
Warning Signs:

Coolant loss, Temperature warning light, Engine rattle on startup, Sudden loss of power

What to Inspect:
  • Ask when the timing belt and water pump were last replaced

Buying Tips for 2001–2002 Saab 900 NG / 9-3 OG

  • ✓The biggest killer is "oil sludge" on B205 engines; insist on proof that the sump has been dropped and cleaned.
  • ✓Check the bulkhead (firewall) for cracking around the steering rack mount, a notorious structural flaw that causes vague steering.
  • ✓Inspect the Direct Ignition (DI) cassette; if the car misfires or struggles to start, this red or black module on top of the engine is likely failing.
  • ✓Test the convertible roof (if applicable) for smooth operation; the hydraulic cylinders are prone to leaking fluid.
  • ✓Check the SID (Saab Information Display) on the dashboard for missing pixels, a very common and annoying fault.
  • ✓Ensure the heater blows both hot and cold; the blend door stepper motors frequently break.
