Recommended Next Step
Stop Driving
Urgency: Stop driving if the temperature gauge enters the hot range, warning lights appear, steam is visible, or coolant is leaking heavily.
Do not keep driving while it is overheating; let it cool and check coolant level and leaks first.
Symptom context
Since this has been gradually getting worse, wear or a developing fault should be checked before it becomes more expensive.
Next step
Let the engine cool, check coolant level safely, look for leaks, and verify fan operation before driving further.
