Buick Skylark Starter Guide: Choosing the Right Part for 1973-1980 Models
Solve your classic Skylark's starting problems, from slow cranking and heat soak to a complete no-start.
- Always test the battery and check cable connections before replacing the starter; it's the most common cause of starting problems.
- A single loud click usually means a bad starter, while rapid clicking often points to a weak battery.
- For V8 engines or any Skylark with hot-start problems ('heat soak'), upgrading to a high-torque mini-starter is the most effective long-term solution.
- You must order a starter that matches your car's specific year and engine (V6 or V8) for correct fitment.
Is Your Skylark's Starter Failing?
Starters on classic cars like the 1973-1980 Buick Skylark can fail from simple old age, wear, or heat. Before you spend money on a new part, always make sure your battery is fully charged and the battery cables are clean and tight. A weak battery is the most common reason for starting issues. If the battery and cables are good, listen for these classic signs of a failing starter:
- Single, Loud Click: You turn the key and hear one solid "CLICK," but the engine doesn't crank. This often points directly to a failed starter motor or the attached solenoid.
- Grinding Noise: A loud grinding or whirring sound when you try to start the engine can mean the starter gear is damaged or not meshing correctly with the engine's flexplate.
- Slow, Labored Cranking: If the engine turns over very slowly, like the battery is weak (but you know it's not), the starter motor is likely worn out and struggling.
- No Sound at All: This could be a dead battery, but if the battery is good, it can also mean a complete failure of the starter motor and solenoid.
- Intermittent Starting: Sometimes it starts perfectly, other times it just clicks. This often happens as a starter begins to fail.
A Common Issue on V8 Models: Starter Heat Soak
One of the most common problems for this generation of GM vehicles, especially those with a V8 engine, is starter "heat soak." This happens when the starter, mounted close to the hot exhaust manifold, gets so hot that its internal electrical resistance increases. The symptom is a starter that works fine when the engine is cold, but cranks very slowly or not at all after a hot engine has been shut off for 10-30 minutes. The car will typically start again once the starter has had time to cool down. While a stock replacement starter will work, it won't solve this underlying design issue.
Choosing the Right Aftermarket Starter for Your Skylark
Since new original equipment (OEM) starters are no longer made, your choice is between new and remanufactured aftermarket parts. It is critical to order the correct starter for your specific engine and year, as different V6 and V8 engines were used across the 1973-1980 range.
Tier 1: Premium New Starters (Bosch)
For owners who want a high-quality, reliable replacement that meets or exceeds original specifications, a new starter from a premium brand like Bosch is a top choice. These units are 100% new, not rebuilt, and are factory tested to perform under extremes of heat and cold. A new Bosch starter is an excellent option for a daily driver or a stock restoration where reliability is key.
Tier 2: Remanufactured Starters (Remy, BBB Industries)
Remanufactured starters from brands like Remy and BBB Industries are a cost-effective option. BBB Industries is a major supplier that remanufactures starters for many parts store brands. These starters are rebuilt to original factory specifications and provide good value. However, forum discussions sometimes show mixed experiences with the long-term reliability of remanufactured parts compared to brand-new units. This tier is a good fit for a budget-conscious repair on a stock vehicle that doesn't have issues like heat soak.
The Upgrade Option: High-Torque Mini-Starters
If you experience heat soak, have a modified engine with higher compression, or simply want a more powerful and efficient starter, a high-torque "mini-starter" is the best solution. These modern, gear-reduction starters are smaller, lighter, and provide more cranking power with less strain on the battery. Their smaller size also provides better clearance from hot exhaust pipes, which directly combats heat soak. Brands like Powermaster are frequently recommended for this upgrade.
| Part Type | Estimated Price Range | Best For |
|---|---|---|
| New Premium (e.g., Bosch) | $150 - $245 | Reliability, stock replacement |
| Remanufactured (e.g., Remy, BBB) | $106 - $160 | Budget-conscious repairs |
| High-Torque / Mini-Starter | $180 - $350+ | Fixing heat soak, modified engines |
Frequently Asked Questions (FAQ)
Is it the starter or the battery?
The easiest way to tell is by listening. A rapid "click-click-click" sound usually points to a weak battery that doesn't have enough power to turn the starter. A single, loud "CLICK" when you turn the key usually points to a bad starter or solenoid. Before buying a starter, always have your battery tested at an auto parts store; the test is free and can save you from replacing the wrong part.
Do I need a high-torque starter?
For a stock Buick V6 or V8 without starting problems, a standard new or remanufactured starter is sufficient. However, if you experience hot-start issues (heat soak), have engine modifications like higher compression, or want faster, more reliable cranking, a high-torque starter is an excellent and highly recommended upgrade.
What are starter shims and will I need them?
Starter shims are thin, stackable metal strips used to adjust the distance between the starter gear and the engine's flexplate. If the distance is incorrect, you may hear a grinding or whining noise during starting. Not all installations require them, but it's important to check for proper gear engagement. Some replacement starters come with a small gauge to help you check this clearance.
Are there any recalls for the 1973-1980 Skylark starter?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls or specific technical service bulletins (TSBs) related to the starter motor for the 1973-1980 Buick Skylark.
Technical Specifications
The 1973-1980 Buick Skylark used several different starters depending on the engine (e.g., 3.8L V6, 5.7L V8) and year. Most are large, direct-drive style starters held by two bolts. It is essential to match the replacement part to your vehicle's specific powertrain to ensure proper fit and function.
