How To Remove A Broken Bolt From A Water Pump

The engine water pump's primary responsibility is to transfer coolant from the radiator back to the engine and maintain a standard operating temperature for the engine. The fasteners on the water pump frequently rust or get broken from repeated use. In this article, MyMROmarts will discuss how to remove damaged bolts on a water pump to help you deal with the problem in time.

How To Remove A Broken Water Pump Bolt

1. Before starting work, you must first allow the engine cooling system to cool down completely to prevent thermal expansion and contraction of the engine, which may cause damage to the engine and other diesel engine parts due to improper operation.

2. Before starting to remove the bolts, find the inlet and outlet connections of the engine water pump, usually some rubber or metal pipes. You can loosen these connections and collect the coolant that comes out of the connections in a container.

3. Find the bolts on the water pump. The water pump is fixed on the engine through bolts. This ensures that the water pump can be stably fixed on the engine. You can find the location of these bolts by closely inspecting the engine case. When removing the bolts, pay close attention to the water pump's joints and keep track of the location and quantity of the bolts.

4. You can use a wrench to loosen the bolts one by one. Use the appropriate size wrench for each bolt to secure the bolt nut, and use the other wrench to loosen in a counterclockwise direction. You can also use a Torx wrench set as needed to loosen bolts of different sizes.

5. Pay attention to controlling the strength of the torque bolt to prevent the engine water pump from being tightened on the engine by using too little force, or from using too much force that causes the water pump bolt to break. You can also apply some thread-locking compound to the bolts before removing them. This is an agent that prevents bolts from loosening on their own and allows them to be securely connected to the water pump. When reinstalling the bolts, apply an appropriate amount of thread locker to the bolts as needed.

6. Replace all damaged bolts with new bolts, and install and tighten the new bolts. Reconnect the coolant inlet and outlet, add new coolant, and check whether the water pump is leaking. After that, start the engine with the starter motor and let it run for a while to see if the water pump is working properly.

The engine water pump is the key to ensuring the normal operation of mechanical equipment. When removing damaged water pump bolts, we must be careful and follow the correct steps to avoid further damage to the water pump and mechanical equipment.
