Your vehicles engine is like the heart of your car. It is full of many moving components, both inside and out, and can wear out over time. When these components star to fail, the engine will not run properly, causing damage. If you hear a weird noise, feel a strange sensation, or see any fluid under your car, don’t hesitate to bring your car down to get a quick check over, it is worth it!
