Does it take long to replace a starter?

Typically, replacing a starter takes about 1 to 3 hours of labor at a repair shop, with DIYers usually budgeting 2 to 4 hours depending on access and tools.

The time required for a starter replacement varies with vehicle design, engine layout, and how easily technicians can reach the component. This article explains what a starter does, why it fails, and what to expect for replacement times on different vehicles.

What is a starter and why it fails

Understanding the starter’s role helps explain why replacement times can vary. The starter motor cranks the engine to start the vehicle, powered by the car’s electrical system. When the starter wears out or its components fail, the engine won’t turn over properly, triggering a repair need.

• Worn brushes or bearings causing sluggish engagement or grinding noises


• Solenoid sticking or failing to engage the bendix gear


• Electrical issues such as bad connections, corroded grounds, or a weak battery


• Seized motor from overheating or internal wear


• Internal gear teeth worn, resulting in slipping or no cranking

In many cases, symptoms include a clicking sound when turning the key, intermittent starting, or a complete failure to crank. Diagnosis often involves confirming adequate voltage at the starter and testing the solenoid and motor function.

How long does it take to replace a starter?

Time estimates depend on how accessible the starter is and whether other components must be moved to reach it. The ranges below reflect typical automotive repairs in professional shops and for experienced DIYers.

Before you review the timelines, note that these are approximate and can vary by model, tool availability, and technician experience. Always get a written estimate before authorizing labor.

• Easy access, rear-wheel-drive or inline-four engines with a clearly visible starter: about 1–2 hours.


• Front-wheel-drive with the starter tucked behind wiring or near the exhaust: about 2–3 hours.


• Mid-size vehicles or V6 engines with moderate obstruction and routine disassembly: about 3–4 hours.


• Compact sports cars or engines with tight spaces, exhaust work, or subframe removal required: 4–6+ hours.

Concluding: Most straightforward replacements fall in the 1–3 hour range at a shop, while more complex layouts can push labor toward 4–6 hours or more. Parts costs usually include the starter itself, plus any mounting hardware and a possible warranty on the unit.

Summary

Replacing a starter is generally a mid-length repair rather than a major engine job. For the majority of cars, plan around 1–3 hours of professional labor, with extra time if access is difficult or additional components must be removed. DIYers should budget 2–4 hours, depending on experience and tools. If you notice trouble starting, get a diagnostic that includes the electrical system and the starter to confirm the cause and estimate.

How many labor hours do you need to replace a starter?

The labor time to replace a starter motor generally ranges from 1 to 4 hours, with the average being about 2 hours. The time can be significantly shorter for vehicles where the starter is easily accessible, or much longer if the starter is in a difficult-to-reach location that requires removing other engine components.

Factors that influence the time

• Vehicle make and model: Different cars have different engine layouts and component placements. A starter on a vehicle with a cramped engine bay will take longer to access and replace than one with easy access. 
• Starter location: On some vehicles, the starter is easily accessible, while on others, it may be "in the valley" of the engine, under the intake manifold, or in another difficult-to-reach spot, requiring more extensive disassembly. 
• Engine type: Diesel engines can sometimes take longer to replace the starter on due to their layout and potentially cramped areas near the frame and exhaust, as noted on JustAnswer. 
• Mechanic's experience: An experienced mechanic may be able to complete the job faster than a less experienced one. 

Is it hard to change out a starter?

Replacing a car starter is a moderately difficult job that depends heavily on the vehicle's make and model. For some cars, it is a simple task that can be done in an hour with basic hand tools, but for others, it can be challenging due to difficult access. The general process involves disconnecting the battery, safely lifting the car, locating and removing the old starter, and installing the new one. 
Key factors that determine difficulty

• Accessibility: The main factor is how easy it is to reach the starter. On some cars, it is right on top or easily accessible from underneath. On others, it may be buried under other components, requiring more disassembly. 
• Vehicle make and model: Each car is different. You may need a specific tool like a universal joint or swivel head ratchet, especially if the bolts are in a hard-to-reach spot. 
• Tools and knowledge: While you can do it with basic tools, you need the right ones. You will need to properly support the vehicle with jack stands, not just a jack.

General steps for replacing a starter

1. Safety first: Park the car on a flat surface, engage the parking brake, chock the wheels, and disconnect the negative battery terminal. Allow the engine to cool down completely. 
2. Lift the vehicle: Use a jack to lift the car and secure it with jack stands to prevent it from falling. 
3. Locate the starter: Find the starter, which is typically where the engine meets the transmission. 
4. Disconnect the old starter: Note and disconnect the electrical cables. Then, unbolt the starter from the engine or transmission. 
5. Install the new starter: Place the new starter in position, reattach the bolts (you may need thread locker on the bolts), and reconnect the electrical wires. 
6. Lower and reconnect: Lower the vehicle, reattach the battery terminal, and double-check all connections before starting the car.

When to consider a professional

• If you are not comfortable with car repair or don't have the proper safety equipment. 
• If the starter is difficult to access on your specific vehicle. 
• If you are unsure if the starter is the actual problem and don't want to waste money on parts.

Can I jump start a car with a bad starter?

No, you cannot jump-start a car with a bad starter, as jump-starting only provides power to the battery and cannot fix a mechanical problem with the starter motor itself. If the starter is faulty, the engine will not crank even with a jump start. However, a jump start can be a temporary workaround if the starter is weak, but it is a sign that the starter needs replacement soon.

Why jump-starting won't work

• A jump start supplies the battery with power from another vehicle, which is necessary to crank the engine. 
• If the starter is bad, it means the engine's starter motor is failing and cannot turn the engine over, even if the battery is fully charged. 
• A bad starter can also cause a jump start to fail. 

What to do instead

• Check connections: Ensure the battery terminals and starter connections are clean and tight. 
• Tap the starter: In some cases, you may be able to temporarily free a stuck starter motor by gently tapping it with a hammer. 
• Push-start (manual transmission): If you have a manual transmission, you can try to push-start the car by rolling it and popping the clutch while in first gear. 
• Replace the starter: The only permanent solution for a bad starter is to replace it with a new one.

How quickly can a starter be replaced?

Starter motor replacement typically takes between 1 and 4 hours, but this can vary significantly depending on the vehicle's make and model. A simple replacement on an easily accessible starter might take under an hour, while a vehicle that requires removing other components like the transmission or engine parts could take 2 to 4 hours or even longer. 
Factors that affect replacement time

• Vehicle Make and Model: Some cars have starters that are very difficult to access, requiring removal of other parts, while some are straightforward. 
• Complexity: The time increases significantly if the starter is not easily accessible and other parts, such as the transmission or intake manifold, must be removed. 
• Technician Experience: A mechanic who is familiar with the specific vehicle may be able to complete the job much faster than someone who is not. 
• Unexpected Issues: Problems like old, corroded bolts or other complications can add extra time to the job. 
• Tools: Having the correct tools can prevent delays, while specialized tools might be needed for certain models.
