Make sure you know exactly what the vendor is quoting

When buying a new engine for your piece of equipment or truck ask your vendor these questions:

  • How complete is this engine and what does it come with?
  • What do you mean by remanufactured, did you tear the engine down and machine the block, head and crank?
  • How long is your warranty and what does it cover?
  • Is freight included in your quote?

You must know exactly what you are getting before buying so you can be confident that what is being quoted will actually work for you and meet or exceed all of your expectations.

Make sure your engine comes with a warranty

If you are looking to buy from a company that does not offer warranties with their product, this is a bad sign. All companies should back what they sell by giving a warranty with a purchase. Warranties ensure you will be covered by the company if anything were to happen with your engine within the time frame of the warranty. Every diesel engine is an investment and it is crucial to have warranty support from the company you are buying it from.

Do they dyno-test their engines?

If you are remanufacturing or buying a remanufactured engine instead of buying a new one, dyno-testing is critical. Dyno-testing will ensure your remanufactured engine has met performance standards, was built correctly, and is ready to go to work when it arrives.

What kind of reviews does the company have?

Reviews, reviews, REVIEWS! Always do your research when buying an engine. Looking into a company’s past reviews is key to accessing the experience you may have when you purchase your replacement engine!
