Scotty Kilmer, the popular social media mechanic, has advised drivers on a tip that can help to make engines run better.<\/p>\n
The mechanic of 55 years regularly posts informative videos to his YouTube channel, giving advice to help drivers make the most of their cars and avoid mechanical trouble.<\/p>\n
This includes five things you shoulder never do in an automatic car and a huge mistake that could leave you with a massive repair bill.<\/p>\n
In one of his most popular videos, Scotty takes a look at a car with several warning lights on, stating that they can often be solved by plugging a scanning tool into the vehicle.<\/p>\n
He explained: \u201cWe start with a simple thing; we plug the scan tool under the dash. In this case it just plugs right in here. Put the key in the on position, with the [warning] lights on but the engine not running.<\/p>\n
And a huge mistake that could leave you with a massive repair bill \/life-style\/cars\/1813450\/scotty-kilmer-mechanic-puddle-damage<\/p>\n

And lo and behold, this baby\u2019s got 14 different [fault] codes.\u201d<\/p>\n In the video, Scotty tries to repair a Lexus SUV which has an engine warning light before it goes for an exhaust emission test.<\/p>\n By plugging the small device into the vehicle\u2019s on-board diagnostic (OBD) port and turning on the ignition, it was able to discover several faults.<\/p>\n The scanner also revealed how fast the car was travelling when the faults were first registered, which helped Scotty to fix the vehicle.<\/p>\n Don’t miss… <\/strong> We use your sign-up to provide content in ways you’ve consented to and to improve our understanding of you.

It\u2019s doing its thing, and look at that there\u2019s no codes at all, even though we didn\u2019t work on the traction control system because the code didn\u2019t come back.<\/p>\n \u201cBecause, as I said, in these things if you get a check engine light come on, that will often turn the ABS [anti-lock brakes] off, it\u2019ll turn the traction control off, even though there\u2019s nothing wrong with those systems, it\u2019s a software thing.\u201d<\/p>\n With nearly 10million views, many motorists were impressed at Scotty\u2019s work in keeping the Lexus on the road.<\/p>\n One viewer commented: \u201cI\u2019m so glad I found your channel! You give honest advice that we need. Thank you, Scotty.\u201d<\/p>\n Another wrote: \u201cScotty, thank you for all the great videos! You have pulled me out of so many binds and saved me a tonne of money and make me laugh all the time!\u201d<\/p>\n![](\"https:\/\/cdn.images.express.co.uk\/img\/dynamic\/24\/590x\/secondary\/diagnostic-tool-4973537.jpg?r=1695409731908\")
