New vs. Remanufactured Water Pumps – Pros and Cons

Sponsored by GMB North America, Inc.

gmb-logo-300x72Total water pump failure can lead to devastating problems, including engine failure. The best approach is to be aware of the signs of failure and replace the water pump right away. If an engine’s water pump is failing, there are two replacement options to consider: a rebuilt/remanufactured water pump or a brand-new one. Before choosing, it’s important to weigh the pros and cons of each option.

Rebuilt/Remanufactured Water Pumps

Pros

The biggest pluses on the side of rebuilt/remanufactured water pumps are:

  • They are often (but not always) cheaper in terms of price of the part
  • Some shops are equipped to do most of the rebuild themselves rather than paying for a rebuilt unit off the shelf

These two things can mean significant up-front savings.

Cons

While saving money on parts is important, be sure to consider these details before purchasing:

  • Does the pump have a warranty? Some rebuilt/remanufactured parts come with a nominal warranty, if any at all.
  • Some water pump remanufacturers use sub-standard kits to keep costs as low as possible, affecting which parts are replaced and acceptable tolerances.
  • Rebuild kits often have oversized bearings meant to compensate for wear on the shaft and housing, but this increases the risk of failure.
  • The process used to clean the pump housing can cause pitting and premature corrosion.

Rebuilding a water pump with a few new materials isn’t the same as replacing the damaged pump with a brand new part. Up-front savings on a rebuild may not end up being the most economical option. Compare costs and shop around before choosing a replacement water pump.

New Water Pumps

Replacing a water pump with an OEM-quality part may cost slightly more up front, but the odds of a recurring problem are greatly reduced. Future problems mean additional time without transportation and more repairs—both of which are costly. The truth is, some manufacturers are offering brand-new water pumps at competitive prices.

Considering the possible problems a rebuilt/remanufactured water pump could potentially cause, paying slightly more for a brand new water pump with a warranty is the better choice.

Today’s vehicle drivetrain systems are far more complex and powerful than ever before. So, you want to make sure you choose a replacement axle that matches the original OE design attributes to ensure proper performance and durability. Avoid installing an inferior axle based on price only, that may not perform properly or worse yet, fail in a few short months. The money saved initially may likely be more than offset by the additional replacement costs, as well as a potential lost customer.

Understanding Intermediate Shafts: What are they… and what do they do?

Intermediate shafts, often referred to as “stub shafts” or “inner shafts” act as the link that couples the CV axle to the transaxle or differential. They allow for the removal and installation of CV axle assemblies without the need to disturb or replace the transaxle or differential oil seal. Use of an intermediate shaft to

What Causes Fuel Pumps to Fail?

Like most vehicle components, natural wear and tear is the unavoidable cause for parts replacement.  Fuel pumps are often out of sight and out of mind for most shop visitors. That’s because they are an as-needed repair and not typically a part of ongoing maintenance. Nevertheless, if you diagnose fuel pump failure, customers will want

Helping Customers Understand the Signs of Fuel Pump Failure

Fuel pump failures are never a one-size-fits-all diagnosis.  Different symptoms indicate different problems and often, the pump will still function—albeit erratically—as it fails.
