YouTube user @scottykilmer said drivers need to beware when car battery terminals get too warm.
According to the expert, corrosion on or around your battery surface can increase resistance within the circuit.
To fix it, you need to clean them.
He said: “Take the battery terminal off, clean them inside and use this funky end in here that has little brushes to clean the top of the terminal and then put it all back together.”
Scotty uses an infrared sensor to see which connections in the car are too warm and need to be cleaned.
He continued: “You can use your bare hands, and if you feel that one wire is normal, but the other one is too hot, start following that wire to either bolt onto stuff or has a little snap-on connection.
“If you take those connectors and they are green inside, that’s corrosion, and you have to clean that well.”
He suggests cleaning corroded wires with a product called Mass Airflow sensor cleaner which costs around £10 on Amazon.
The video has had more than 439,000 views on Youtube, and people were left blown away after discovering this hack that will save them £1,000s.
One said: “You’re really a wise man Scotty. Not only that you are an experienced mechanic, but you also understand electricity and physics. I’m glad I found your channel.”
A second pointed out: “Excellent video, Scotty. Very educational and basically all about common sense in the electrical maintenance of your vehicle. It answers a lot of issues in past problems I endured with my cars. Love your work, Scotty.”
A third pointed out: “Great advice! I never thought about using the heat as a diagnostic tool. Faulty grounds can actually start house fires (usually at the outlet or panel), but I never thought about it from the point of prevention.”
This comes after a mechanic revealed what to do if your car is making a knocking noise.
