Choosing the Right Starter Motor for Your 1972-1980 Buick Skylark
Solve your classic Skylark's starting problems, from slow cranking and heat soak to a no-start condition.
- Diagnose 'heat soak' (slow cranking when hot) as a primary issue before buying a part.
- For V8 engines or modified cars, a high-torque mini-starter is a worthwhile upgrade over a stock replacement.
- Always confirm your battery and cables are good before replacing the starter; it's the most common cause of starting problems.
- A single click usually means a bad starter, while rapid clicking often means a weak battery.
Is Your Skylark's Starter Failing?
Starters on classic cars like the 1972-1980 Buick Skylark can fail from age, wear, or heat. Before you replace the part, make sure your battery is fully charged and the battery cables are clean and tight. A weak battery is the most common cause of starting issues. If the battery is good, listen for these sounds:
- 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.
- Rapid Clicking/Chattering: A fast "click-click-click-click" sound usually means the battery doesn't have enough power to turn the starter over. This is more likely a battery or alternator issue than a bad starter.
- Grinding Noise: A loud grinding sound when you try to start the engine can mean the starter gear is not meshing correctly with the flexplate, or the gear is damaged.
- Whirring Sound, No Crank: If you hear the starter motor spinning freely but the engine isn't turning, the starter's drive gear has failed and is not engaging the flexplate.
- No Sound at All: This could be a dead battery, a failed ignition switch, or a complete failure of the starter motor and solenoid.
A Common Issue: 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 engine has had time to cool down significantly. Using a starter heat shield or a modern, more efficient high-torque starter can solve this problem.
Choosing the Right Aftermarket Starter
For your Skylark, you have a few good options for new aftermarket starters. Original OEM starters are no longer manufactured, but today's parts offer a range of choices from stock replacements to significant upgrades.
Tier 1: OE-Style Replacement
Brand Example: ACDelco
If your Skylark is stock and you want a direct, no-fuss replacement, an OE-style starter is a great choice. ACDelco is GM's official parts brand and offers new starters designed to meet the original specifications. These are typically large, heavy, direct-drive units similar to what the car came with. They are reliable and a good value for a standard restoration or daily driver.
Tier 2: Performance & Problem-Solver
Brand Examples: Powermaster, Proform
If you have a modified engine with higher compression or suffer from heat soak, a high-torque, gear-reduction starter is a smart upgrade. Brands like Powermaster and Proform specialize in these. These "mini-starters" are smaller, lighter, and use a gear system to multiply torque, allowing them to spin the engine with less effort and less electrical draw. Their smaller size can also provide more clearance from hot exhaust pipes, further reducing heat soak issues.
Tier 3: Aftermarket Value
Brand Example: MPA (and other store brands)
Brands like MPA offer new starters that serve as a cost-effective alternative. They are built to function as stock replacements and provide a reliable option that comes with a new part warranty, which you don't get with a used part from a junkyard.
| Type | Estimated Price Range |
|---|---|
| New Aftermarket (Standard) | $62 - $150 |
| New Aftermarket (High-Torque) | $180 - $385 |
| Remanufactured | $50 - $150 (plus core charge) |
Pro Tip: Check Your Flexplate
Before installing your new starter, take a moment to inspect the teeth on your engine's flexplate. You can do this through the starter mounting hole. Look for any broken, chipped, or excessively worn teeth. A damaged flexplate can quickly ruin a brand-new starter.
Frequently Asked Questions (FAQ)
Do I need a high-torque starter?
For a stock Buick V6 or 350 V8, a standard starter is usually sufficient. However, if you have engine modifications (like higher compression), experience heat soak issues, or simply want faster, more reliable cranking, a high-torque starter is an excellent and highly recommended upgrade.
🎬 See how a high-torque mini-starter fixes slow cranking issuesIs it the starter or the battery?
The easiest way to tell is by listening. A rapid clicking noise points to a weak battery. A single loud click usually points to the starter. Before buying a starter, always have your battery tested at an auto parts store—it's free and can save you from replacing the wrong part.
🎬 Watch: How to diagnose car battery and starter problemsDo I need to use shims when installing the new starter?
Sometimes. Starter shims are thin metal strips used to adjust the distance between the starter gear and the flexplate. If the distance is wrong, you'll hear a grinding or whining noise. Not all installations require them, but it's important to check for proper engagement. Many new starters come with a small gauge or instructions on how to check this clearance.

No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) specifically for the starter motor on this vehicle.

Fitment for the 1972-1980 Buick Skylark starter varies based on the engine (V6 or V8) and specific year. It is critical to match the part to your vehicle's exact configuration. Key specifications to consider are the number of teeth on the gear, mounting bolt pattern (straight or staggered), and whether it is a standard direct-drive or a high-torque gear-reduction design.
