After work intended to address a cooling fan that runs after the engine is switched off, repeat the original conditions in a safe place and check whether the symptom returns. Record how long it runs, recent driving conditions, and whether the engine temperature was high. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Check the manual because some vehicles intentionally run the fan briefly; keep clear of it even when parked. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
