Lexus Engine Save with This Easy DIY Test

Has your Lexus developed an unusual sound upon starting up? Here’s a common source of noise that could ruin your engine unless you use this easy DIY diagnosis test before it is too late. Plus, what to inspect on your Lexus to avoid problems.

A good habit to get into is to be mindful of what your engine should sound like from the day you bought it or after it has been serviced by a mechanic who tells you that your engine sounds fine and is in good running condition.

The reason for this being a good habit is that it conditions your hearing―without having to even think about it―when something is not right with your engine and your ears automatically send a warning to your brain. Call it instinctual if you will, but there are cues of sight, sound, smell, and feel that often are there but for whatever reason might wind up ignored until a real problem develops―such as a blown Lexus engine.

In other words, trust your instincts when it comes to your car.
