What Are The Costs Of Water Pump Repair And Replacement?

What Does A Water Pump Do?

The water pump guarantees that coolant flows into the coolant system quickly in order to cool down the engine.

Your vehicle’s engine runs optimally at a specific temperature that has to be maintained throughout its operation. If that temperature isn’t maintained, your engine will overheat, resulting in serious damage to the engine.

With such an important role in temperature regulation and engine operation, it’s crucial that you replace your water pump prior to it going bad.

Signs Your Water Pump Is Damaged

• Coolant Leak

  A damaged water pump may leak from any gasket or the axle sealing. The gaskets ensure that the coolant stays sealed with an uninterrupted flow of water. They can, however, deteriorate over the course of time and be rendered useless. This, then, causes the coolant to leak out from underneath the pump.

  If you observe a puddle of water or coolant beneath the front end of your vehicle, then you’re likely looking at water pump failure and need to take your car to an auto repair shop immediately.

• Water Pump’s Axle Loose
  

  The water pump is turned by a serpentine timing belt in order to pump coolant. If the water pump axle deteriorates, the timing belt may loosen. When this happens, you will have to undergo a complete and total replacement of the water pump.

  In order to get ahead of complete water pump replacement, remove the entire serpentine or timing belt and feel the axle. If you feel any play in the axle, then proceed with replacing it immediately.

• Squealing Noise
  

  Coolant may leak into the bearings of the water pump when it (the water pump) goes bad. This will dry out the bearings lubrication, resulting in a squealing noise whenever the engine is running.

  Should you hear a squeal from the water pump, replace it as soon as possible. Holding off on the replacement can lead to engine death if you keep driving.

• White Smoke From The Radiator
  

  White smoke emanating from your radiator is a clean indication of water pump failure. This steam comes from the overheating engine, which can be the result of a damaged water pump. This situation calls for an immediate pulling over of your vehicle, waiting for your engine to cool, and calling your mechanic.

• Overheating Engine
  

  The chief responsibility of the water pump is to funnel coolant into the engine system in order to bring its temperature down. Should that pump system fail, expect to see an increase in engine temperature on the dashboard gauge.

  While temperature gauge readings may be affected by other malfunctions, it’s best to take your vehicle to a certified mechanic and let them do a diagnostic. You risk far-reaching damage to the cylinders, head gasket, and pistons if you don’t.

• Unstable Engine Temperature
  

  A loose impeller on the water pump axle may cause noticeable intermittent problems. This can cause the car to work fine one moment, then overheat the next. In instances of fluctuating engine temperatures like this it’s best to check the water pumps and replace them if necessary.

Can You Repair A Water Pump?

A broken water pump requires immediate attention.

You are more than capable of repairing your water pump, but you’ve got to decide between a rebuilt water pump or a brand new one. Either choice comes with their own set of benefits and drawbacks.

Benefits

The biggest pros supporting using a rebuilt (or remanufactured) water pump are:

• Typically cheaper to purchase than a new water pump.

• Many shops have the capabilities to accomplish a majority of the rebuilds themselves, rather than paying to get a rebuilt water pump unit off the shelf.

These two benefits have a major impact on you saving money upfront during your replacement.

Drawbacks

Even with the prospect of savings, rebuilt water pumps come with their own set of drawbacks. It is important to keep note of these when deciding which type of replacement water pump to choose:

• Some rebuilt parts come with little (if any) warranty.

• There are certain parts that are made with sub-standard kits. This is done by manufacturers in an effort to keep costs as low as they can. This, however, impacts which parts can be replaced and their acceptable tolerances.

• These rebuild kits tend to have oversized bearings that are intended to overcompensate for the wear on the housing and shaft, with an increased risk of failure.

• The pump housing’s cleaning process can cause pitting and premature corrosion.

Using a few new materials to rebuild your water pump is not the same as replacing the damaged pump with a new part.

While you’ll save money on the front end of things with a rebuild, it might still not be the best choice. Shop around and compare the costs before choosing your water pump replacement.

Water Pump Repair Costs

The average cost to repair a damaged water pump is between $678 - $811. This price range includes the cost of the parts as well as the cost of labor to form a national average.

It does not, however, include any taxes, fees, or costs associated with your particular make and model.
