A Mechanic's Guide to the 2005-2006 Saab 9-2X Accessory Drive Belts
Keep your "Saabaru" running right by understanding its unique two-belt accessory drive system.
- Your 2005-2006 Saab 9-2X uses a two-belt system for its accessories, regardless of whether it is an Aero or Linear model.
- Aftermarket brands like Bando and Mitsuboshi are OEM suppliers for Subaru and offer the best combination of quality and value.
- Always replace both the main (Alt/PS) and A/C belts at the same time for complete service.
- Inspect belts regularly for cracks and listen for squealing; ignoring a worn belt can leave you stranded.
The 'Saabaru' Secret: It's a Subaru
First, let's be clear: your 2005-2006 Saab 9-2X is a rebadged Subaru Impreza wagon. The 'Linear' model is an Impreza 2.5RS, and the 'Aero' is a WRX. This is great news for you, because it means parts are readily available and the mechanical systems are well-documented. When it comes to the accessory drive, all 9-2X models from this period—both Linear and Aero—use the same two-belt setup.
One Job, Two Belts
A common point of confusion is how many belts are needed. Your 9-2X has two separate accessory drive belts, and it's best practice to replace them both at the same time.
- Main Belt: This is a 5-rib belt that drives the alternator and power steering pump.
- A/C Belt: This is a 4-rib belt that drives only the air conditioning compressor.
When shopping, make sure you are purchasing two distinct belts. Ordering a single "serpentine belt" will leave the job half-finished.
Common Ordering Mistake
Do not assume your car uses a single serpentine belt like many modern vehicles. You must order two separate belts for a complete replacement on any 2005-2006 Saab 9-2X: one for the Alternator/Power Steering and one for the A/C.
Symptoms of a Failing Drive Belt
A worn belt will almost always give you a warning before it breaks. Listen and look for these signs:
- Squealing or Chirping: This is the most common symptom. You'll hear a high-pitched noise from the engine bay, especially on cold starts, when turning the steering wheel, or when you turn on the A/C.
- Visible Damage: A visual inspection is the best diagnostic tool. Look for cracks, fraying, glazing (a shiny surface), or missing chunks of the belt's ribs.
- Accessory Problems: If your power steering feels heavy or your A/C blows warm, the belt could be slipping.
- Battery Light: If the battery warning light comes on while driving, the belt may have snapped or is slipping badly, preventing the alternator from charging the battery.
Choosing the Right Aftermarket Belt: OEM Quality Without the Price
You do not need to buy an expensive "Genuine Saab" part from a dealer. For Japanese vehicles like the Subaru-built 9-2X, brands like Bando and Mitsuboshi are often the original equipment manufacturers (OEM). This means they produced the exact same part that was installed at the factory. Choosing one of these brands gives you OEM quality and perfect fitment at a much lower aftermarket price. They are trusted choices in the Subaru community and are ideal for your 9-2X.
Pro Tip: Inspect Your Pulleys
While the belts are off, spin the tensioner and idler pulleys by hand. They should spin smoothly and quietly. If you feel any roughness, hear any grinding noises, or see any wobble, replace them at the same time as the belts to avoid a future failure.

Frequently Asked Questions (FAQ)
How often should I replace the accessory belts?
A good rule of thumb is to replace them every 60,000 to 90,000 miles, or sooner if you see signs of wear like cracking or fraying. It's wise to inspect them during every oil change.
Do the Aero (turbo) and Linear (non-turbo) models use different belts?
No. For the 2005-2006 model years, both the Aero and Linear trims use the same two-belt accessory drive system.
Is this a difficult job to do myself?
For a DIYer with basic tools, this is a very manageable job. The main belt uses a manual tensioner that is adjusted with a couple of bolts. The A/C belt can be slightly more difficult as it is a stretch-to-fit design, but it is still feasible at home. Many video tutorials for the 2005-2007 Subaru Impreza and WRX apply directly to this job.
Are there any recalls for the drive belts on my 9-2X?
No. There are no recalls or common Technical Service Bulletins (TSBs) related to the accessory drive belts for this vehicle. Any open recalls you find are likely for the Takata passenger airbag inflators.
