Steps

This procedure covers the removal and replacement of the starter motor on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including disconnection of electrical connections and proper torque specifications.

Warnings

⚠️Always disconnect the negative battery terminal first and wait at least 90 seconds before working on electrical components to prevent accidental engagement or short circuits

⚠The starter motor is heavy (approximately 8-10 lbs). Support it properly when removing the mounting bolts to prevent it from falling

⚠If the engine has been recently run, allow it to cool as the starter and surrounding components may be hot

ℹ️Take photos of electrical connections before removal to ensure correct reinstallation

Preparation

Park vehicle on level ground and apply parking brake
Place wheel chocks behind rear wheels
Allow engine to cool if recently operated
Raise front of vehicle and secure on jack stands rated for vehicle weight
Remove front passenger side wheel for better access (optional but recommended)
Gather all tools and new starter motor before beginning work

Procedure

1
Disconnect battery
Open hood and locate the battery. Using a 10mm wrench, loosen and remove the negative battery cable from the battery terminal. Secure the cable away from the battery post. Wait at least 90 seconds before proceeding.
2
Access starter location
From underneath the vehicle, locate the starter motor on the lower front side of the engine, between the engine and transmission bellhousing on the passenger side. You may need to work from both above (through engine bay) and below (under vehicle) for different connections.
3
Remove engine under cover if equipped
If your vehicle has a plastic under cover, remove the fasteners securing it to access the starter. Some fasteners may be push-type clips. Set cover and hardware aside.
4
Disconnect starter electrical connections
Locate the two electrical connections on the starter solenoid. First, remove the 12mm nut securing the large B+ battery cable to the solenoid terminal post and carefully pull the cable off. Then disconnect the smaller push-on connector from the S terminal by pulling it straight off. Keep hardware organized.
⚠Do not allow the B+ cable to contact any ground or metal surfaces, as it carries direct battery voltage even with negative disconnected
Torque spec
Starter Solenoid Nut12 Nm (9 lb-ft)
5
Remove heat shield if present
Some models have a heat shield bolted to the starter or nearby area. If present, remove the 10mm bolts securing the heat shield and set aside with hardware.
Torque spec
Heat Shield Bolts10 Nm (7 lb-ft)
6
Locate and access mounting bolts
The starter is secured by two bolts through the bellhousing. Identify both bolt locations. The upper bolt is accessed from above in the engine bay, while the lower bolt may be accessed from below or through the wheel well opening. The long bolt typically requires a socket extension.
7
Remove upper starter mounting bolt
Using a 14mm or 17mm socket (depending on bolt head) with extension, remove the upper starter mounting bolt. This bolt threads into the transmission bellhousing. Keep bolt in a safe location.
⚠Support the starter with one hand as you remove this bolt to prevent it from dropping
Torque spec
Starter Mounting Bolts50 Nm (37 lb-ft)
8
Remove lower starter mounting bolt
Remove the lower mounting bolt using the same socket size. This bolt is typically longer and may require a longer extension to reach. Once both bolts are removed, the starter will be free from the bellhousing.
Torque spec
Starter Mounting Bolts50 Nm (37 lb-ft)
9
Remove starter motor
Carefully wiggle and pull the starter motor away from the bellhousing. The nose of the starter fits into a pilot hole in the bellhousing, so you may need to rotate it slightly while pulling. Lower the starter down and out from under the vehicle. Be prepared for the weight.
10
Inspect mounting surface and prepare new starter
Clean the mounting surface on the bellhousing with a wire brush if needed. Inspect the ring gear through the starter opening for any damaged teeth. Verify the new starter matches the old unit in mounting hole positions, electrical terminal configuration, and overall dimensions.
11
Install new starter motor
Guide the new starter into position, aligning the nose with the pilot hole in the bellhousing. Ensure the starter is fully seated against the bellhousing mounting surface. Rotate slightly if needed to achieve proper alignment.
12
Install mounting bolts
Thread both starter mounting bolts by hand to avoid cross-threading. Start with the upper bolt, then the lower bolt. Once both are hand-tight, use a torque wrench to tighten both bolts to specification in a crisscross pattern.
Torque spec
Starter Mounting Bolts50 Nm (37 lb-ft)
13
Reconnect electrical connections
Reconnect the small S terminal connector by pushing it firmly onto the terminal until it clicks. Then place the B+ cable terminal onto the solenoid stud and install the 12mm nut, tightening to specification with a torque wrench.
Torque spec
Starter Solenoid Nut12 Nm (9 lb-ft)
14
Reinstall heat shield and under cover
If a heat shield was removed, reinstall it with the original bolts and torque to specification. Reinstall the engine under cover if applicable, ensuring all fasteners are properly secured.
Torque spec
Heat Shield Bolts10 Nm (7 lb-ft)
15
Reconnect battery and test
Reinstall the negative battery cable to the battery terminal and tighten the 10mm nut to specification. Ensure the connection is clean and tight. The vehicle is now ready for testing.

Reassembly

Reinstall wheel if removed and torque lug nuts to specification (110 Nm / 80 lb-ft)
Lower vehicle from jack stands
Double-check all electrical connections are secure and properly routed
Verify no tools or parts were left in engine bay or under vehicle

Verification

Turn ignition key to START position and verify engine cranks smoothly and starts
Listen for unusual noises from the starter during cranking (grinding, clicking, whirring)
Verify starter disengages immediately when key is released to RUN position
Check that all warning lights on instrument cluster function normally after start
Test start the vehicle 3-4 times with engine cold and warm to ensure consistent operation
Inspect under vehicle for any fluid leaks or loose components after test starts
