The overheating is likely a *consequence* of the alternator failure, not the direct cause. Here's why:
* Loss of Power: Without a functioning alternator, various electrical components, including the water pump (in many cars), may stop working. The water pump circulates coolant to prevent overheating. If it stops, the engine will overheat rapidly. This is the most likely scenario.
* Increased Load: The engine may have been working harder to compensate for the loss of power steering, generating more heat. This alone might not cause overheating, but it contributes to the problem if the water pump is also failing.
In short: The alternator failure is the root cause, and the overheating is a symptom of the subsequent loss of essential electrical functions.
What to do:
* Do NOT attempt to drive the car further. Continuing to drive with an overheated engine can cause significant and costly damage.
* Call a tow truck.
* Once the car is safe, have a mechanic diagnose and repair the alternator and check for any other damage caused by the overheating (e.g., warped head gasket).
It's crucial to address this issue promptly to prevent further damage to your engine.
