$150 – $700
Varies by vehicle and root cause.
Short trips in cool weather or on the highway are usually okay, but the cooling fan matters most in traffic and at idle. Watch your temperature gauge and pull over if it gets hot. Get it fixed soon to avoid overheating.
Repairs typically range from $150 to $700. A relay or fuse is inexpensive, while a new fan motor or control module costs more, plus labor depending on your vehicle.
It can be if the fan isn't running, because the engine can overheat in traffic and cause serious damage. On the highway it's less critical, but you should still address it promptly.
It can, especially during idling or stop-and-go driving when airflow is low and the fan does most of the cooling. Keep an eye on the temperature gauge and avoid heavy traffic until it's repaired.
