Accessory Drive Belt Guide for the 1989-1996 Mazda 626
Keep your 626 running smoothly by understanding its accessory drive belts and knowing when to replace them.
- The 1989-1996 Mazda 626 can have multiple engine types (I4, V6), each with a different belt configuration; verify your engine before buying.
- Squealing noises, visible cracks, and accessory failure are key signs that your belt needs immediate attention.
- For best results, choose aftermarket brands like Bando or Mitsuboshi, which are often the original OEM suppliers for Mazda.
- While replacing the belt, it is wise to inspect the tensioner and idler pulleys for wear, as they are also common failure points.
Understanding the Accessory Drive Belt System in Your 626
The 1989-1996 Mazda 626 spans two different vehicle generations, the GD (1989-1992) and GE (1993-1996), and came with various engines, including 2.0L and 2.2L 4-cylinders and a 2.5L V6. Because of these differences, the accessory drive belt setup varies. Some models use a single serpentine belt, while others use multiple V-belts to power accessories. It is crucial to identify your specific engine to get the correct replacement belts.
Symptoms of a Failing Accessory Drive Belt
A worn-out drive belt will give you several warning signs. Ignoring them can lead to being stranded.
- Squealing or Chirping Noises: This is the most common symptom. A high-pitched squeal, especially on startup, during acceleration, or when the A/C is on, often means the belt is slipping because it's loose or worn.
- Visible Wear and Tear: A visual inspection can reveal a lot. Look for cracks, fraying, missing ribs, or a glazed, shiny appearance on the belt's surface.
- Power Steering or A/C Failure: If turning the steering wheel suddenly becomes difficult or the air conditioning stops blowing cold, the belt may have failed and is no longer powering those systems.
- Engine Overheating: The drive belt often runs the water pump. If the belt breaks, the pump stops circulating coolant, causing the engine to overheat quickly.
- Battery Warning Light: A slipping or broken belt can't properly spin the alternator, which charges the battery. This will cause the battery light to illuminate on your dashboard.
Don't Ignore a Bad Belt Tensioner
Sometimes, the belt itself isn't the problem. A buzzing or rattling noise could point to a failing belt tensioner or idler pulley. A bad tensioner can't keep the belt tight, causing symptoms similar to a worn belt and can lead to premature belt failure. On V6 models, the idler pulleys are a known point of failure and can seize up after many years and miles.
Choosing the Right Aftermarket Belt
For a Japanese vehicle like the Mazda 626, aftermarket belts from brands that are also OEM suppliers are an excellent choice. They often provide the same quality as the dealer part without the high price tag.
- Tier 1 (OEM-Equivalent): Bando and Mitsuboshi are frequently original equipment manufacturers for Japanese cars. Choosing a belt from one of these brands is as close to getting a genuine Mazda part as you can get, ensuring excellent fit and durability.
- Tier 2 (High-Quality Aftermarket): ACDelco is a well-respected aftermarket brand that produces reliable and durable belts. Brands like Gates and Dayco are also solid choices that meet or exceed OEM specifications.
Pro Tip: Since Bando and Mitsuboshi are often the original suppliers for Mazda, opting for their aftermarket offerings can give you OEM quality at a fraction of the cost.

Frequently Asked Questions (FAQ)
How often should I replace the accessory drive belts on my Mazda 626?

Is replacing the drive belt a DIY job?
For a moderately experienced DIY mechanic, yes. The process typically involves loosening the tensioner or accessory bolts to release tension, removing the old belt, and routing the new one. Access can be tight, especially on V6 models. Ensure you have the correct belt routing diagram for your specific engine.
