Ford Mustang Starter Guide: 1975-1982 Models
Everything you need to know before replacing the starter on your 1975-1982 Ford Mustang.
- First, identify your car: 1975-1978 is a Mustang II, 1979-1982 is a Fox Body. The replacement job is much harder on the Mustang II.
- Watch for 'hot start' issues, where the car won't start when warm. This is a common sign of a failing starter due to heat soak.
- Due to the difficult labor on Mustang II models, choosing a high-quality new aftermarket starter from a brand like Bosch or Remy is a wise investment.
- Before replacing the starter, always check that your battery is fully charged and that the battery cables and engine ground straps are clean and tight.
Is Your Mustang a Mustang II or a Fox Body?
Before you buy a starter for your 1975-1982 Mustang, you need to know which car you really have. This year range covers two completely different Mustang generations.
- 1975-1978 Ford Mustang II: These cars are known for a very difficult starter replacement, especially on V6 and V8 models. The job often requires lowering the steering rack and removing a crossmember to get the starter out.
- 1979-1982 Ford Mustang (Fox Body): This platform is much easier to work on. The starter is more accessible, making replacement a more straightforward job that many owners can do at home.
Knowing your specific model is critical for understanding the labor involved.
Symptoms of a Failing Starter
A bad starter usually gives you a few warnings before it fails completely. Here’s what to look and listen for:
- Single Loud Click: You turn the key, hear one loud 'click' from the engine bay, but the engine doesn't turn over. This often points to a bad starter solenoid.
- Slow, Labored Cranking: The engine turns over very slowly, like the battery is weak, even when it's fully charged. This can mean the starter motor is worn out and drawing too much power.
- Grinding Noise: A harsh grinding sound when you try to start the car can mean the starter gear is not engaging properly with the flywheel, or the teeth on either gear are damaged.
- No Sound at All: If you turn the key and get nothing—no click, no crank—the problem could be in the electrical path to the starter, or the starter itself has completely failed.
Known Issue: Hot-Start Problems
A very common issue on older Fords, including these Mustangs, is "heat soak." After a long drive, the starter gets very hot from the nearby exhaust manifolds. This heat increases the electrical resistance inside the starter, making it struggle or fail to crank the engine. After the car cools down for 20-30 minutes, it might start normally again. This is a classic sign of a starter on its way out. A new, high-torque starter or adding a heat shield can help solve this problem.
Choosing the Right Aftermarket Starter
For a vehicle of this age, new original equipment (OEM) parts are generally not available. Your choice is between new aftermarket and remanufactured aftermarket parts. Given the extreme difficulty of replacing the starter on 1975-1978 models, investing in a quality new part is highly recommended to avoid doing the job twice.
- Tier 1: Bosch: Generally viewed as a high-quality option with good reliability. If you want peace of mind, Bosch is a solid choice.
- Tier 2: Remy & WAI Global: Both are well-known aftermarket brands that offer new (not remanufactured) starters. They are considered good alternatives to more expensive brands. Some users report good experiences, though long-term durability can be a variable.
- Tier 3: BBB Industries: This company is a major producer of remanufactured starters. They are a common, budget-friendly option found in many auto parts stores. Quality can be hit-or-miss, as is common with many remanufactured parts.
Consider a High-Torque Upgrade
For 1979 and later Fox Body Mustangs, upgrading to a modern Permanent Magnet Gear Reduction (PMGR) starter is a popular choice. These starters are smaller, lighter, and more powerful than the original units, providing better clearance for headers and overcoming hot-start issues more effectively.
Starter Replacement Cost
The cost to replace your Mustang's starter depends on your model year and whether you do it yourself.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Starter | $111 - $190 |
| Remanufactured Starter | $80 - $150 |
| Shop Labor (Fox Body, 1979-1982) | $120 - $250 |
| Shop Labor (Mustang II, 1975-1978) | $350 - $600+ |
Labor costs are estimates and will vary by location. The significant increase for the Mustang II reflects the added complexity of the job.
Frequently Asked Questions (FAQ)
Is it hard to replace the starter on a 1975-1982 Mustang?
It depends entirely on the year. For 1979-1982 Fox Body models, it is a relatively easy job (Difficulty: 2/5). For 1975-1978 Mustang II models, it is very difficult (Difficulty: 4/5) and involves removing other components like the steering rack to gain access.
What's the difference between a new and a remanufactured starter?
A new starter is made with all-new components. A remanufactured starter is an old unit that has been disassembled, cleaned, and rebuilt with new or refurbished parts to meet factory specifications. While remanufactured parts are cheaper, new parts often offer better reliability and longer warranties.
My battery and alternator are good, but the car won't start. Could it be the starter?
Yes. If the battery has over 12.4 volts and you just hear a 'click' or a slow crank, the starter is the most likely culprit. Also, check your battery cables for corrosion and ensure the engine ground connection is clean and tight, as these can cause similar symptoms.
Are there any recalls on the starter for these Mustangs?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database and other TSB sources show no specific recalls or technical service bulletins for the starter motor on 1975-1982 Ford Mustangs.
Technical Specifications
Starter specifications vary based on the engine (I4, V6, or V8). The original starters were large, direct-drive units. Many aftermarket options for the Fox Body (1979-1982) are smaller, more efficient Permanent Magnet Gear Reduction (PMGR) style starters, which are a common upgrade. Always verify fitment for your specific engine and transmission combination before purchasing.
