Accessory Drive Belt Guide for the 1970-1975 Dodge Challenger
Keep your classic Challenger's accessories running smoothly by choosing the right V-belts for your engine.
- Your 1970-1975 Challenger uses multiple V-belts, not a single serpentine belt.
- You must verify the exact number and size of belts required for your specific engine and accessory combination (A/C, power steering, etc.).
- It is best practice to replace all accessory belts at the same time for maximum reliability.
- High-quality aftermarket brands like Gates, Continental, and Dayco offer performance that meets or exceeds the original 1970s specifications.
Understanding the V-Belt System in Your Classic Challenger
The accessory drive system on a 1970-1975 Dodge Challenger is a classic example of a multi-belt setup. These V-belts, named for their V-shaped cross-section, sit in the pulleys of each accessory. This system is robust, but it requires checking multiple belts for wear and proper tension. Because there are many engine options for this generation of Challenger, from the Slant-6 to the 440 V8, the exact number and length of the belts can vary significantly. Always confirm which belts your specific car needs before ordering.
Symptoms of a Failing Accessory Drive Belt
A worn or failing V-belt will usually give you a few warning signs. Ignoring them can leave you stranded.
- Squealing Noises: This is the most common symptom. A high-pitched squeal, especially when you start the engine, accelerate, or turn the steering wheel, often means a belt is slipping due to wear or improper tension.
- Visible Damage: Inspect your belts. If you see cracks, fraying, or a shiny, hardened surface (known as glazing), the belt is old and needs to be replaced.
- Accessory Problems: If your headlights seem dim, your battery isn't charging, the engine temperature rises quickly, or the power steering becomes heavy, a belt may have failed or is slipping badly.
- Vibrations: Worn-out belts can cause unusual vibrations from the engine bay as they struggle to grip the pulleys correctly.
Pro Tip: Replace Belts as a Set
If one belt is worn out, the others are likely the same age and condition. It is highly recommended to replace all accessory drive belts at the same time to ensure reliability and proper system function.
Choosing the Right Aftermarket Belts
For a classic vehicle like the 1970-1975 Challenger, original Mopar belts are generally unavailable. However, modern aftermarket belts made from advanced EPDM rubber compounds are often more durable and longer-lasting than the original 1970s parts. Here’s a look at trusted brands:
- Premium Brands (Gates, Continental): Gates is a highly respected name in the automotive world, and many classic car owners prefer them for their durability and precise fit. Their heavy-duty belts are an excellent choice for any Challenger, from a daily driver to a high-performance build. Continental is another top-tier brand known for quality that meets or exceeds OEM standards.
- Standard Brands (Dayco): Dayco is a well-known manufacturer that provides reliable, quality belts. They are a great option for owners looking for a balance of performance and value, and they are a common choice for both professional shops and DIY mechanics.
Common Ordering Mistake
The biggest mistake is ordering belts without confirming your car's specific needs. A 318 V8 with A/C and power steering uses a different set of belts than a 440 V8 without A/C. Check a parts catalog or measure your existing belts to ensure you get the right lengths.

Frequently Asked Questions
How many belts does my 1970-1975 Challenger have?
It depends entirely on your engine and factory options. A base model with no power steering or A/C might only have one or two belts. A fully-optioned V8 model could have three or four separate belts. You must verify the setup on your specific car.
Should I replace my pulleys with the belts?
It's a good idea to inspect the pulleys when you change the belts. If the grooves are worn down or polished smooth, they can cause new belts to slip and wear out prematurely. If you see any wobble or hear grinding noises from a pulley, the bearing is bad and it should be replaced.
How tight should a new V-belt be?
A common rule of thumb is that the belt should have about 1/2 inch of deflection when you press on it firmly at the longest point between two pulleys. 🎬 Watch: A mechanic explains how to get V-belt tension just right. Over-tightening can damage the bearings in your alternator or water pump, while a loose belt will slip and squeal.
Are there any recalls for my Challenger's belts?
No, there are no specific recalls from the NHTSA related to the accessory drive belts for the 1970-1975 Dodge Challenger. Any recalls for this vehicle were for other issues like axles, seats, or wheels.
