Questions that narrow it down

General checks. Answering them does not confirm the failed part on this vehicle.

Worth checking first

  • A visible radiator leak and a heater-core smell in the cabin are different paths.
  • A replaced head gasket without leak language is not this job.

Safety

When not to keep driving

  • If the temperature climbs, you smell coolant strongly, or steam comes from the engine bay, stop as soon as it is safe. Do not keep driving a leaking cooling system.

About the data

Counts come from replacement.guide aggregates for this model year. Component evidence comes from structured complaint categories and reviewed component mentions in complaint summaries. Owner-situation evidence comes from reviewed symptom language in complaint summaries. Reports are signals, not diagnoses.

How to read this page

PRIMARY components are the validated first-line associations for this job. RELATED components can be involved but are ranked after PRIMARY even when they have more reports. A report involving a component does not prove that component caused the problem.
