If you experience reduced heat or a complete lack of it inside the cabin, your water pump may be to blame. The water pump plays a role in regulating the temperature of the coolant that passes through the heater core, affecting the cabin’s heating system.

What Causes A Water Pump to Fail?

Understanding the root causes of water pump failure can help you prevent it. Here are some common factors that contribute to a bad water pump:

1. Improperly Installed Belt

If the water pump belt is too tight or misaligned, it can cause the water pump to seize and ultimately fail. Proper installation is crucial to prevent this issue.

2. Wrong Coolant

Using contaminated or incorrect coolant can lead to rust and corrosion inside the water pump, accelerating its deterioration.

3. Dry Running

Running a water pump with insufficient coolant can lead to overheating and damage to the pump’s seals. Overheated seals are prone to failure and can result in coolant leakage.

4. Blown Gaskets

Blown gaskets can introduce air into the cooling system, affecting the water pump’s performance and potentially leading to failure.

5. Failure to Flush Coolant on Time

Regular coolant maintenance is essential. Neglecting to flush and replace coolant at recommended intervals can result in sediment buildup and, subsequently, water pump damage.

6. Wear and Tear

Like any mechanical component, water pumps wear down over time due to normal use. Regular inspections can help catch issues before they become severe.
