How We Research and Update Guides
1. Define the vehicle boundary
We identify the make, model, model year, engine, and trim where the answer changes. A procedure that is correct for one model year is not automatically correct for another.
2. Start with manufacturer information
Where available, we check the owner’s manual, service information, technical service bulletins, warranty documents, and safety recalls. These sources take priority over forum anecdotes.
3. Use owner reports as evidence of patterns
Owner reports can show what commonly fails, what a warning feels like in practice, or which part number owners actually receive. We treat them as leads, not as proof of a specification.
4. Verify part numbers and fitment
For parts, we check the listing’s stated fitment against the vehicle boundary. We do not present a part as a guaranteed fit when the listing is ambiguous.
5. Separate diagnosis from repair
A guide should tell the reader what to check, what result means what, and when to stop. It should not encourage parts-swapping without a diagnostic reason.
6. Review and update
We add a reviewed date when we re-check an article. If a procedure, part number, or specification changes, we update the article rather than leaving a known-wrong instruction in place. Errors are handled through our corrections policy.
Limits
Our guides are general information. A vehicle can have a fault that no article can diagnose remotely. Safety-related symptoms, brake faults, fuel leaks, and high-voltage systems should be inspected by a qualified professional.
