So, you've decided to buy a used car engine for your car to replace the old one. Maybe the original engine got damaged in a collision. Or perhaps your car is old with heaps of sentimental value, and you'd like to keep driving it for years to come. Whatever your reason for replacing an engine, the currently installed auto part needs to go, and a new one needs to take its place.

Opting for a Used Car Engine 

After considering your options and weighing them against your budget, you've decided to get a second hand car engine. Depending on your circumstances, this could be a wise decision. However, buying a used engine is still a significant investment and requires due diligence before you make any buying decisions.

After all, you don't want to end up with a used engine that only works for a while before presenting you with a whole set of new problems!

So, before you decide on anything, here are five things you should know when buying a used car engine.

5 Things to Remember Before You Buy a Second Hand Car Engine

1. Buy from a Reputable Seller

One of the most important things to consider when buying a used car engine is to find a reputable seller. Things would be slightly more relaxed if you were buying directly from a personal seller, say family or friend. However, if you're buying from car wreckers or through online sellers, be sure to do your homework. Look at the reviews that the seller has received in the past.

Trust your instincts. If the deal sounds too good to be true, it probably is. Or, if you're feeling a little unsure about the seller, it's okay to keep looking for other options.

For a big purchase like a car engine, it's worth being extra careful before dipping into your pocket.

2. Find Out About the Engine's History

When I say 'history', I'm referring to things like the engine's mileage, it's age, servicing, accidents, and maybe even the reason why it's on sale in the first place. Don't hesitate to ask the seller anything about the engine's history. You have every right to know, as these details help you gauge just how much wear and tear it may have. Plus, it'll help you get a sense of the engine’s remaining useful years.

That includes the reason it's up for sale, as well. For example, if it is a second hand car engine that had a nasty accident written in its past, you'll need to verify that there is no internal damage to it.

3. Ask if the Engine Had Been Tested

As part of doing your homework before buying a used car engine, you should ask if it has been tested yet. That way, you can rest easy knowing that an impartial third party has checked the engine for problems.

You could have the engine tested in a few ways. Of course, the worst option would be to buy it and see if it works, but we'd like to avoid this option altogether!

Generally, there are two ways an engine can be tested. There's the Compression Test and the Run Test. With a Compression Test, the purpose is to measure the pressure inside the engine and make sure none of it leaks out. It will tell you about the condition of engine parts like its valves, piston rings, and more. The Run Test, on the other hand, is used to search for leaks and tune the engine. During a Run Test, the engine is usually mounted on a stand and not inside the car itself.

4. Check for Compatibility with Your Car

This one sounds obvious, but it needs to be said. Do your research ahead of time to confirm that the used car engine you're considering is compatible with your car.

Sure, car manufacturers often use the same type of engine across different models. However, this isn't always the case, so it's worth double-checking ahead of time. You wouldn't want to end up with an engine that won't fit!

5. Inquire about Warranty

Last but not least, find out if there's a warranty for the engine. You probably won't get the kind of guarantee that comes with a brand-new engine, of course. But even second hand car engines, especially reconditioned and rebuilt ones, come with warranties for at least a few months. In some cases, you might be able to pay a little extra to extend that warranty.

Now that you know what to look for when shopping for a used car engine, here comes the tough part. Shopping around for sellers who can get you the engine you need can sometimes be a headache. If you're unlucky, you may end up having to make lots of calls and visit lots of sellers to get what you need.
