Learn About Your Engine!

We often get asked about engines here at Eric’s Car Care. One of our customers wrote to us asking about his 2012 Hyundai, with a 3.5 V6. He was told that his engine had been seized. Our mechanics have come up with this response, and although it’s a response to Jake’s issue, you guys can definitely learn from his issue!


Dear Eric’s Car Care,


I was told I have a seized engine in my 2012 Hyundai, with a 3.5 V6. How does one check to confirm this conclusion? –Jake


I assume your car suddenly died on you, and the engine would not restart. The first thing we’d do is check your engine oil level.


Running out of oil is a frequent cause of engine seizing. So, if you’re out of oil, that’s a big clue that you ran out of lubrication, and your engine parts rubbed together into a permanent sculpture, rather than a functioning engine. If checking the oil is inconclusive, or if there is still sufficient oil in the crankcase, we’ll try to turn the crankshaft with a wrench.


Every crankshaft has a pulley, which is held on by a bolt on the front of the engine. You can put a wrench on that bolt and use it to try to turn the crankshaft. So, we’ll put a socket on the bolt, attach a breaker bar and see if the crankshaft will turn. If it won’t turn, that tells you that you no longer have engine parts. You have an engine part.


If you don’t have confidence in the mechanic who diagnosed it for you, you can have it towed to a mechanic you trust more and ask him to do these tests.


However, if you know you did something drastic, like never changing the oil, running the car out of oil, or overheating the bejeebers out of the engine, then you may very well have seized it, Jake. In which case, the engine is toast.


Good luck, Jake. And give us a visit if you need a repair!
