One of the worst things you can do is buy a used car with a bad engine. So, there are a number of things to look out for. While it’s impossible to cover everything in one setting, this video will teach you to look out for the basics. Scan the vehicle with an OB2 scanner. If there are problems to detect, the scanner will let you know. Too many problems, and it’s not worth taking the vehicle for a test drive or spending any more time talking to the seller.
It should be easy enough to find the car’s scan port under the steering wheel. Crank over the engine and check for those telltale lights on the dash. Check out your app for confirmed codes, and pending codes. A P1000 code signifies that someone cleared the “check engine” light. That could spell trouble in the future. Next, pop the hood and look at the engine compartment. Make sure the hood support is strong. Look for cleanliness and obvious damage or leaks. If the engine is over-cleaned, it could mean there’s something the owner is trying to hide. There’s good information here that could save you headaches down the line.
