Did you know that the water pump in your car should last between 60,000 to 90,000 miles? If you have the suspicion that it might be time for a new water pump and are wondering how to tell and how to replace a water pump, you are in the right place.

Keep reading to learn the ins and outs of water pumps. 

How Do You Know It’s Time to Replace?

Before you contact a reputable place to order your water pump from like PumpBiz there are a few ways to tell whether you need a water pump or not. If you ever notice a coolant leak near your timing belt it might be a sign that there is an issue with the water pump.

You can also check by pulling the water pump pulley back and forth. If you can easily move it can be a sign that the bearings and the shaft are loose.

How to Replace a Water Pump

If you feel comfortable tackling the task of replacing your own pump then you will want to make sure you start with an engine that is completely cooled down. Disconnect the negative battery post and then drain all the coolant from the engine.

Next, remove the accessory belt from the engine and all the hoses that are attached to the water pump. Find the bolt that is holding the water pump to your car’s engine and loosen it.

Take out the old seal and gasket that is in between the water pump and engine and clean the area. Before you install the new water pump take some time to inspect everything else in the cooling system to make sure everything looks right. Check parts like the hoses and the thermostat.

After inspecting the rest of the cooling system attach the new water pump in the engine and follow the exact instructions for torque levels while you are sealing it. Then, connect all of the hoses and the accessory drive belt to the front of the water pump. Last but not least, fill up the cooling system with the right amount of coolant.

Once the coolant is filled you will want to turn the pump with your hand manually to make sure that it is spinning and operating correctly. In a few weeks make sure to double-check the seal to ensure that it is still sealed tight.
