How Urgent Is A Water Pump Replacement?
As the water pump has the crucial job of cooling the engine, it’s best to get it repaired or replaced as soon as you spot an issue.
Although your car may still run with minor water pump issues, it could damage other critical car parts like the engine if ignored for long. So get your car fixed by a professional to avoid expensive repairs and additional replacement costs.
When To Replace Your Water Pump
The water pump replacement cost should not deter you from considering the service. The pump prevents engine overheating by continuously circulating coolant from the radiator to the engine. As a result, a water pump malfunction is a serious issue as you’ll be looking at overheating, premature wear, and severe damage to vital car parts.
Here are a few signs to help you spot a water pump malfunction:
High coolant temperature: The engine heats up without a good water pump, leading to high coolant temperatures. It’s usually indicated by an engine temperature warning light or elevated engine temperature reading on the dashboard.
Radiator steam: Steam billows from the engine as the coolant can’t circulate in an overheated radiator when the water pump malfunctions.
Abnormal noises: A loose accessory belt, pulley, or worn-out bearings in the water pump cause squealing and whining engine sounds, especially when accelerating.
Fluid leaks: Green, orange (rusty coolant), or red-colored coolant may leak out when water pump components develop cracks or wear out. You can also check for frothy oil on the oil dipstick for possible internal leaks
Fluctuating fluid gauge: If your temperature gauge needle oscillates between normal and high, your car’s water pump may be the culprit. A bad radiator or air bubbles can also cause inconsistent temperature readings.
3 Water Pump FAQs
Here are some of the most common queries about water pumps and water pump replacement cost, as well as their answers.
1. What Is A Water Pump?
A water pump is a mechanical impeller pump which is a device used to increase the pressure and flow of fluid.
You can find the water pump underneath the timing belt. That’s why experts advise replacing the water pump when you get your timing belt changed.
The water pump plays a key role in your vehicle’s cooling system by circulating coolant from the engine to the radiator. This protects the engine and other essential parts from overheating.
2. How Does The Water Pump Work?
When you start your engine, the fan belt and the water pump’s central axis also begin to turn — creating a centrifugal force. This force creates a suction that allows the pump to receive coolant from the radiator and send it to the engine.
The coolant absorbs the engine heat before it travels to the radiator, which cools the coolant again.
Usually, the water pump can move around 7500 gallons every hour. However, the water pump adjusts its speed according to how fast the engine runs. It does so to absorb the heat that increases with engine speed — ensuring that the engine maintains normal temperatures.
3. How To Replace A Water Pump?
Each engine model may have its own belt drive system or water pump replacement steps. So it’s better to call an expert to help you replace or repair the water pump system.
