Accessory Drive Belts for the 1958-1970 Cadillac Eldorado
Keep your classic Eldorado's accessories running smoothly by understanding its unique V-belt system and choosing the right parts.
- Your 1958-1970 Eldorado uses multiple V-belts, not a single serpentine belt; confirm your car's specific configuration before buying.
- Squealing noises are a direct warning of a worn or loose belt that requires immediate inspection to prevent being stranded.
- Modern aftermarket belts from brands like Gates, Dayco, and Continental are superior in quality and durability to original-era belts.
- For best results and reliability, inspect pulleys for damage and consider replacing all accessory belts at the same time.
Understanding Your Eldorado's V-Belt System
The 1958-1970 Cadillac Eldorado is a product of its time, featuring a robust multiple V-belt system. This means several individual belts, named for their V-shaped cross-section, are responsible for driving different components. The exact number of belts, their lengths, and how they are routed depend on your car's specific year and optional equipment, most importantly, whether it has air conditioning. Because of these variations, it is critical to identify the correct belts for your specific vehicle before purchasing. When one belt shows signs of wear, it is wise to inspect all of them.
Signs of a Failing Accessory Drive Belt
A worn V-belt will almost always provide warning signs before it fails completely. Paying attention to these symptoms can prevent a breakdown.
- Squealing Noises: This is the most common sign of a problem. A high-pitched squeal, especially on startup or when turning, often means a belt is loose or worn out.
- Visible Damage: Inspect the belts regularly. Look for cracks, fraying, glazing (a shiny, smooth surface), or missing chunks of rubber. Any visible damage means the belt should be replaced.
- Accessory Malfunctions: If your battery isn't charging (dimming lights, battery warning light), the alternator belt may be slipping. If the engine temperature starts to rise, the water pump belt could be failing, which can lead to serious engine damage.
- Vibrations: Worn-out belts can cause unusual vibrations as they struggle to grip the pulleys correctly.
Choosing the Right Aftermarket Belts
Original equipment belts for these classic Cadillacs are no longer produced. Fortunately, modern aftermarket belts from reputable brands offer superior materials and construction compared to the originals from the 1960s. The rubber compounds used today are far more resistant to heat, oil, and degradation. All the brands listed below are considered quality choices.
Premium Brands (Excellent Quality & Durability):
- Gates: Often regarded as a top choice among classic car enthusiasts for their durability and precise fit. Their heavy-duty or "Green Stripe" belts are known for longevity.
- Continental: A well-respected manufacturer that produces high-quality belts often used as original equipment on many vehicles.
Standard & Reliable Brands:
- Dayco: A long-standing brand that produces reliable and durable belts. Their "Top Cog" V-belts are a popular choice for classic cars.
- ACDelco: As GM's parts brand, ACDelco offers professional-grade belts that are a smart choice for any Cadillac owner looking for an OE-style replacement.
Pro Tip: Replace Belts as a Set
When replacing one belt, it's best practice to replace all of them. They are relatively inexpensive, and the labor to access them is the same. This ensures all your belts are the same age and provides peace of mind.

Frequently Asked Questions (FAQ)
How many accessory belts does my 1958-1970 Eldorado have?
It depends on the year and options. Most cars will have at least two or three belts for the alternator, water pump, and power steering. Cars with air conditioning will have additional belts. It's essential to check your specific car's configuration before ordering.
Can I replace the V-belts myself?
Yes, this is a very manageable job for a DIY mechanic with basic hand tools. The process involves loosening the accessory (like the alternator), removing the old belt, fitting the new one, and then properly tensioning it before tightening everything back up.
What is proper belt tension?
A new belt that squeals is often improperly tensioned. A general rule of thumb is that at the longest span between pulleys, you should be able to twist the belt about a quarter turn (90 degrees) with your fingers. A belt that is too loose will slip and squeal, while a belt that is too tight can damage bearings in the accessories.
Are there any recalls for the drive belts on these cars?
No. There are no NHTSA recalls specifically for accessory drive belts on the 1958-1970 Cadillac Eldorado. Belt replacement is considered a standard maintenance item.
