A Comprehensive Guide to Accessory Drive Belts for the 1971-1978 Dodge Colt
Keep your classic Colt running right by understanding its essential V-belts.
- Your 1971-1978 Colt uses multiple V-belts, not a single serpentine belt.
- Squealing noises and visible cracks are clear signs that a belt needs replacement.
- A failed alternator or water pump belt is a critical issue that requires immediate attention.
- Reputable aftermarket brands like Dayco and Gates are excellent choices; select based on price and availability.
Understanding Your Colt's V-Belt System
The 1971-1978 Dodge Colt, a rebadged Mitsubishi, uses a simple and reliable V-belt system. Unlike modern cars with a single serpentine belt, your Colt has multiple individual belts. This can be an advantage, as the failure of one belt may not disable the entire system immediately. However, it also means there are multiple belts to inspect and maintain. These belts are made of durable rubber compounds and are designed to last for thousands of miles, but they do wear out over time and require regular inspection.
Symptoms of a Failing Accessory Drive Belt
Knowing the signs of a worn belt can prevent you from being stranded. Pay attention to these common symptoms:
- Squealing Noises: A high-pitched squeal, especially when starting the engine or during acceleration, is the most common sign 🎬 Watch: How to find the source of a belt squeak of a loose or worn belt.
- Visible Wear and Tear: Inspect your belts for cracks, fraying, glazing (a shiny, smooth surface), or missing chunks of rubber. Any visible damage means the belt should be replaced.
- Battery Warning Light: If the belt driving the alternator breaks or slips, the battery will stop charging, and the warning light on your dashboard will illuminate.
- Engine Overheating: The failure of the water pump belt will cause the engine's temperature to rise quickly, leading to serious damage if not addressed immediately.
- Loss of Accessories: If your Colt has power steering or A/C, those systems will stop working if their respective belts fail.
Critical Failure Warning
A broken belt for the water pump or alternator is a critical failure. If you see the battery light or the temperature gauge rises into the red, pull over safely and shut off the engine as soon as possible 🎬 See this guide on replacing a broken or missing belt to prevent catastrophic engine damage.
Choosing the Right Aftermarket Belt: Dayco vs. Gates
For a vehicle from the 1970s, original OEM parts are virtually nonexistent. Fortunately, the aftermarket provides high-quality replacements. Dayco and Gates are two of the most reputable brands available, both with long histories of producing reliable belts.
Forum discussions among classic car owners show that both Dayco and Gates are considered top-tier choices. Neither brand is definitively better than the other for this application; both produce durable V-belts that meet or exceed the original specifications. Modern belts from these brands are made with advanced EPDM rubber compounds that resist heat, oil, and ozone better than the original neoprene belts. Your choice between Dayco and Gates can confidently be based on price and availability.
Pro Tip: Replace in Sets
Since replacing one belt requires accessing the front of the engine, it's often a good idea to inspect all the belts at the same time. If they are of a similar age or condition, consider replacing them all at once to save on future labor and prevent another failure.

Frequently Asked Questions (FAQ)
How many accessory belts does my Dodge Colt have?
The exact number depends on your car's engine and options. A base model will have at least two belts (alternator and water pump). A car with air conditioning and/or power steering will have additional belts for those components, totaling three or four.
What's the difference between a V-belt and a serpentine belt?
Your Colt uses V-belts, which are older-style, individual belts for each component. Modern cars use a single, flat, ribbed serpentine belt to run everything. V-belts are generally easier for a DIY mechanic to replace one at a time.
How do I know if the belt is tight enough?
A common rule of thumb for V-belts is the "twist method." On the longest span between two pulleys, you should be able to twist the belt about 90 degrees (a quarter turn) with your fingers, but no more. An overly tight belt can damage 🎬 Watch: A time-saving hack for perfect V-belt tension the bearings in your alternator or water pump.
Were there any recalls for the Dodge Colt's drive belts?
No, a search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls for accessory drive belts on the 1971-1978 Dodge Colt. This is a standard maintenance and wear item.
