Excavator Water Pump – The Ultimate FAQ Guide

Excavator water pumps are vital excavator cooling system components for your excavator’s engine. It is a key component of the excavator’s engine cooling system. Without it, your excavator engine will blow, as it will not be able to cool properly.


It’s true that:

Excavator engines use diesel. Cooling is an important concept for these types of engines. You need to understand all about your excavator water pump. This guide is going to enlighten you on:

  • What an excavator water pump is as well as its functions in an excavator
  • How to repair and/or replace your excavator water pump
  • How to take care of your excavator’s water pump

Keep following this guide for more tips and information.


1. What is An Excavator Water Pump?

An excavator water pump is an essential component of the excavator’s cooling system. Your excavator cannot function as it should without it. The engine will ultimately cease functioning completely without the excavator water pump.

Figure 1 - Excavator Water Pump

2. How Does An Excavator Water Pump Function?

Your excavator uses a centrifugal water pump to push the coolant. It pushes the coolant through the excavator’s cooling system so that it can cool the engine.

Figure 2 - Excavator Pump Working Principle

Here’s the deal:


Your excavator water pump has a limited lifespan. You, therefore, have to take care of it to ensure it serves you for long. You’ll further save a lot of money that could otherwise be directed to repairs and replacement of parts. Keep reading this guide to find out how to take care of your excavator water pump.


3. What is the Optimal Water Level for An Excavator Water Pump?

Your excavator cooling system uses coolant to cool the engine. The cooling system should have the recommended amount of coolant level for the excavator water pump to push the coolant through the system.

You can find the recommended amount in your excavator’s service and operational manual. If your excavator coolant level decreases, consider checking for leaks in the cooling system. A temporary way to handle this issue is to top off coolant to the cooling system.

Do not mix coolants that have different chemistries. It will only contaminate your coolant, which has some significant negative effects on the water pump

KS cannot place further emphasis on the importance of having the correct amount of coolant in your excavator’s cooling system. It’ll help prevent premature engine failure, as diesel engines heat up quickly, and this heat needs to be managed.


4. Where is the Excavator Water Pump Found?

Your excavator water pump is located in the engine’s compartment, near the radiator and the excavator’s cooling fan.


5. What Are the Common Problems with Excavator Water Pumps?

Your excavator’s water pump will ultimately wear out over time. It’ll require either repairs or replacements, depending on the level of damage.

Check out some of the most reported excavator water pump problems that you may face over time when using your excavator:

  • Weep Hole Leakages: you may observe a weep hole leakage on your excavators’ water pump. If your excavator water pump is new, you may observe this type of leakage is normal and takes only about 10 minutes as the mechanical seal sets itself.


Figure 3 - Weep Hole Leakage


The most common cause for weep hole leakages is contaminated coolants. Your coolant may be contaminated if it has the following signs:

  • Your excavator engine’s operating temperature gets hotter than usual.
  • There may be a grinding noise coming from your excavator’s cooling system.
  • Your excavator cooling system may start rusting.
  • An odor (hot maple syrup) may start coming from the engine area.
  • Rust and Corrosion: Rust and corrosion may appear on the surface of your excavator water pump. It could be because the water pump’s impeller fins are completely corroded, rendering the pump useless as it is unable to pump coolant correctly.

Figure 4 - Rust and Corrosion


The most common cause for rusting and corrosion is using contaminated coolants.

  • Deposit Buildup: Your excavator water pump may have buildups from deposits, sludge, etc. which clogs your water pump. Clogging has serious consequences, as your pump will not be able to pump coolant properly.

Figure 5 - Deposit Buildup

  • Cavitation: Cavitation is a clear sign that your excavator water pump has an unwanted inlet. You’ll know that your excavator has cavitation when the coolant has bubbles. This unwanted inlet damages your water pump’s internal components due to pressure imbalance.

Figure 6 - Cavitation

  • Damaged bearings and shafts: When your excavator water pump’s internal components are not properly aligned or when there is an unwanted inlet, your excavator water pump will fail.

Figure 7 - Damaged Bearings

Misaligned internal components are mostly caused by a misaligned or significantly worn-out belt. Your belt may be overly tight, which may cause bending and misalignment.

6. How Can I Properly Diagnose My Excavator Water Pump?

Your excavator engine cooling relies heavily on the correct diagnosis of your excavator water pump. You need to correctly diagnose the problem your excavator has so that you can repair it correctly.

Here are some of the best diagnoses you can make when you realize your excavator water pump has the earlier mentioned common issues:

  • Weep Hole Leakage: Weep hole leakages are mostly caused by using contaminated coolants. You can solve this issue by completely and thoroughly cleaning your excavator’s cooling system before installing a new water pump. It would also be best if you’d use your excavator manufacturer’s recommended coolant.

Your favorite mechanic can also advise you on which coolant to use, depending on your location and environmental conditions.


Kindly note that running your excavator on a dry water pump, even for a few seconds, will damage the water pump’s mechanical seal.

  • Rust and Corrosion: Rust and corrosion on the surfaces of your water pump is undisputed evidence of contaminated coolant in your excavator’s cooling system. Another probable reason for this issue is a damaged pressure cap that allows air inside the cooling system, catalyzing the rusting process.

You’ll need to install a new high-quality excavator water pump. Ensure you flush and clean thoroughly your excavator’s cooling system before installing your new excavator water pump.

  • Cavitation: Cavitation will require you to replace your entire excavator water pump. After properly cleaning your excavator’s cooling system and then installing your new water pump, fill the excavator’s cooling system with the recommended type and amount of coolant.
  • Damaged Internal Components: Damaged internal components cause a lot of wear to the water pump. You’ll need to buy and install a new high-quality excavator pump. Ensure that the belt’s tension is correctly set, as it will affect the effectiveness and lifespan of your excavator’s water pump.
  • Noisy Water Pump: When your excavator water pump produces a lot of noise, your impeller or bearings are most likely damaged. You’ll need to replace these components to prevent further damage.

7. How Should I Repair My Excavator Water Pump?

Repairing your excavator water pump is an essential part of caring for it. Repairs are, by far, cheaper than the complete replacement of the excavator water pump.

To repair it, you’ll need to examine the excavator water pump, diagnose it correctly and replace any component that may be affecting your excavator.

Figure 9 - Excavator Water Pump Repair

You can use the diagnosis you’ve read from this guide to repair your excavator water pump. You should, however, get replacement parts from a reputable professional company. Also, all repairs must be done by a certified expert.

It will help you prevent any unnecessary damages as well as preventing the annulment of your excavator’s warranty cover.


8. How Should I Replace My Excavator Water Pump?

Replacing your excavator water pump is more expensive than replacing them. You’ll first need to order a new water pump from a reputable professional company.


Here’s how you can replace your excavator water pump:

  • First, you’ll need to ascertain that your excavator engine is cool, before starting the replacement process. It’ll help prevent self-injury as the engine can burn you pretty badly.
  • Then, you’ll need to remove the excavator’s belt drive and any other component that may get in your way as you try to access the water pump. In most excavator models, you may be required to remove the fan. It’s vital to use your excavator’s service and operator’s manual for this process.
  • Proceed to remove your excavator’s water pump hoses. A lot of coolants may pour out at this stage. Loosen all the bolts properly to prevent the breaking of bolts in their cavities.
  • Inspect keenly your excavator’s thermostat, coolant hoses, and pressure caps.
  • Clean the excavator’s cooling system properly. It will help prevent contaminating the new coolant that you’ll soon add to the cooling system.
  • You can then proceed to install the new water pump. The water pump should fit smoothly. Do not hit it so that it may fit correctly. Follow other installation instructions keenly, as instructed by the manufacturer.
  • You’ll then proceed to tighten the bolts.
  • Attach the excavator’s water pump hoses. They should be in good shape.
  • Refill the coolant into your excavator’s cooling system. It is vital to refill the recommended coolant quantity and quality.
  • Attach the belt drive to your water pump. Ensure that its tension is correctly set. It’ll help prevent premature excavator water pump failure. It’ll also prevent rapid belt drive wear.
  • Visually inspect the area to ascertain that there is no leakage in the cooling system. There may be some seepage for about 10 minutes, as the mechanical seal sets itself properly. There may be some further leaks that should not alarm you – the engine will soon get hot when you start it.

9. How Much Does An Excavator Water Pump Cost?

It’s true that:

Today’s market is full of different excavator makes and models. Each make has its own excavator water pump design, and perhaps additional components. It is therefore difficult to clearly state the exact price of your excavator water pump.
