How To Prevent The Water Pump From Freezing

The engine water pump of construction machinery is an important component that circulates coolant to guarantee the engine's regular operation. However, during the cold winter months, the water pump may freeze, preventing the engine from working correctly. In this article, MyMROmarts will explore how to successfully prevent water pumps from freezing and offer various techniques for thawing water pumps to guarantee that construction machinery continues to run properly in extreme weather situations.

How To Prevent The Water Pump From Freezing

Choose The Right Coolant

When running construction machinery in cold areas, it is critical to use the right coolant. Choose low-freezing-point antifreeze, which has a lower point of freezing and can protect the liquid from freezing in extremely cold weather. The antifreeze should also be chosen according to the manufacturer's recommendations, with the proper dilution ratio, and the freezing point of the coolant checked on a regular basis to ensure that it is within the suitable range.

Maintain Engine Operating Temperature

A further essential element in preventing the water pump from freezing is keeping the engine warm. The engine's operating temperature should be within an acceptable range. If the temperature is too low, the coolant will not reach the optimal temperature, increasing the danger of freezing. In a chilly area, you might think about utilizing an engine preheater to heat the coolant ahead of time to guarantee that it is at the right level when the starter motor starts the engine.

Maintain Water Pump Sealing Performance

A common cause of water pump freezing is due to poor sealing performance, causing air and water to enter the interior of the pump body, forming a freezing phenomenon. Therefore, check and maintain the seals of the water pump in time, such as O-rings, gaskets, etc., to ensure that they are intact, thereby reducing the risk of coolant leakage and freezing.

Avoid Water Pump Overcooling

When parking construction machinery, try to park it in a dry and ventilated place to avoid exposure to cold environments. If the mechanical equipment is not used for a long time, consider using auxiliary equipment such as heaters to provide heat sources to maintain the temperature of the mechanical equipment and avoid overcooling of the water pump.

How To Unfreeze A Water Pump

Use An External Heat Source

If your engine water pump has frozen, it could be thawed with an external heat source, which might include a heater or flame gun. However, you must exercise extreme caution during defrosting to avoid more damage to the water pump, and you must also maintain operational safety.

Defrost With Coolant

Another method for thawing a frozen water pump is to introduce coolant at the appropriate temperature. When the water pump freezes, pour a proper temperature coolant into the water pump, wait for it to gently melt, and then defrost the water pump. This procedure needs patience, but it is quite safe and will not harm the pump more.

Use Deicing Agent

In the event of an urgent need to thaw the water pump, an appropriate deicing agent can be used. The ice melter can quickly heat and thaw frozen coolant and allow the water pump to defrost quickly. However, it should be noted that when using the deicing agent, follow the instructions to avoid damage to the water pump and other diesel engine parts.
