Start with when it grinds
This Accord has intermittent grinding on cold starts. Its starter was replaced roughly five months earlier. GoTech does not promise that another starter will solve it before seeing the starter teeth and ring gear.
Record whether the noise happens cold, hot, on every start or only sometimes. Grinding during engagement is a different complaint from a click with no crank, slow cranking or an engine that cranks normally but will not run. Do not treat those as the same diagnosis.
▶ Complaint, previous repair and uncertainty 0:48Before opening up the starting circuit
This case needs removal access, a close view of the starter teeth and a borescope view of the ring gear. Use the Accord service procedure for access, battery isolation, engine rotation and reassembly.
Isolate the battery before disconnecting the starter cable. The video works around a connected positive cable; that is not the method recommended here. DENSO’s general starter guidance starts with disconnecting the vehicle’s negative battery cable and directs you to the vehicle service manual.
Before any start attempt, remove hand-rotation tools from the engine and keep hands, cables and loose equipment clear. Do not keep cranking a grinding starter to gather more examples.
Check the starter teeth and the whole ring gear
- Inspect the starter’s drive gear.
With the starter removed, GoTech looks at the teeth for damage. That is one side of the engagement; it cannot tell you the condition of the teeth around the engine’s ring gear.
- Inspect a complete circumference.
The presenter uses a borescope through the starter opening and a reference mark to work around the flexplate. Use the prescribed safe engine-rotation method. Looking at one visible patch does not clear the rest of the teeth.
- Let the inspection change the plan.
GoTech does not find obvious ring-gear damage in the filmed inspection and continues with starter replacement. Visible damage, incomplete access or an uncertain inspection would need resolving before calling another starter the whole fix.
Full-circumference inspection checklist
- Use the vehicle’s isolation and hand-rotation procedure before opening the starter area.
- Establish a visible reference point, then inspect successive sections until that same point returns.
- Note any damaged teeth, uncertain views or areas you could not inspect. An incomplete view is still unresolved.
- Remove the rotation tool and clear the work area before any start attempt.
The filmed inspection supports the decision in this case. It does not supply tooth dimensions, engagement tolerances or inspection criteria for every starter system.
The new part introduced a different problem
Keep two problems separate. The original complaint was cold-start grinding. The replacement introduced a mounting mismatch; it does not explain the earlier noise by itself.
During installation, a bolt tightens but the replacement starter can still move. GoTech compares the mounting areas and finds a difference that allows the bolt to bottom before it clamps the starter.
Stop if the starter is not securely clamped. Match the replacement part, mounting surfaces and specified hardware. Resolve a mismatch with the supplier and the vehicle’s service information before operating it.
▶ Watch for the mounting mismatch 11:48Close the job before calling it repaired
Use the correct part and hardware, then complete the vehicle-specific reassembly and tightening steps. DENSO also calls for comparing the replacement’s mounting and connections with the original and checking the finished installation.
The video mentions intake gaskets still waiting to arrive. Do not treat the temporary filmed assembly as a complete return-to-service procedure. Account for required gaskets, intake connections and anything else disturbed during access.
Replacement acceptance: before the first start
- Application and fit. Confirm the correct starter and compare the mounting, drive end and connections; the recently installed part is not automatically the correct reference.
- Secure mounting. Confirm proper seating and prescribed hardware. A bolt reaching its limit while the starter moves is a stop, not a pass. Use the vehicle’s torque specification.
- Complete access work. Finish the required gaskets and disturbed connections. The video’s pending intake-gasket work is not a finished installation.
- Safe recheck. Account for tools, cables and loose equipment, then check operation and the original cold-start complaint. Quiet warm starts alone do not settle an intermittent cold-start noise.
Quiet starts are useful evidence, with a limit
What is demonstrated
GoTech makes repeated starts without the grinding heard in the original complaint. That supports an improvement during those checks.
What still needs confirming
Finish the outstanding reassembly, verify secure mounting and repeat the check under the original cold-start conditions. The video does not establish long-term performance or show the final gasket installation.
Before replacing it again
Could a replacement starter still be the problem?
Yes. Its history does not establish its present condition or fit. In this case GoTech checks the teeth and finds a separate mounting mismatch during replacement.
If one section of the ring gear looks good, can I rule it out?
No. The demonstrated inspection works around the full circumference. Use the proper inspection and rotation procedure; inaccessible or uncertain areas remain unresolved.
Should I use the washers shown in the video?
Do not take them as a general repair instruction. Confirm the correct starter and hardware and resolve the fitment issue with the manufacturer or supplier before operation.

What this guide covers
The 2007 Accord 2.4L grinding case and its diagnostic reasoning. Battery-cable handling and the washer workaround are explicitly not endorsed. No universal starter fitment, torque specification or complete filmed return-to-service is claimed.
