A MECHANIC who has been working in garages since the 1960s has shown how understanding what’s going on under your car’s hood isn’t as complicated as it may seem.
The seasoned technician, Scotty Kilmer, noted in a YouTube video that many parts in a vehicle’s engine bay are color-coded. Action Auto Parts
Scotty (@scottykilmer) added in his clip that knowing these color-coded sections’ meanings can help you implement fixes to save hundreds a year instead of hiring help, specifically with fluids.
Routine car fluid changes include engine oil, coolant, transmission fluid, brake fluid, and windshield wiper fluid.
Scotty clarifies that automakers typically mark these fluids with yellow or blue coloring.
An example would be an oil dip stick’s yellow end that points outward from its sheathe.
The professional mechanic clarified that auto manufacturers additionally use red or green colors to mark parts under your hood that you can fix.
Scotty said: “Everything else, you can leave to the experts and let your mechanic handle the more complex things.
“In other words, [don’t touch] the non-color-coded parts and stuff that are black or gray.”
But this isn’t the only part of your vehicle that’s color-coded.
You can use your fuse box’s colored diagram to replace a blown air conditioning (A/C) fuse.
Fuse boxes are under a vehicle’s hood in its engine compartment adjacent to the battery, but you can streamline your search for this location using your car’s owner’s manual.
Lift the fuse box’s lid off to reveal its underside’s color-coded diagram labeling each section of your fuse box.
Find and remove your AC fuse to inspect the component visually.
Blown fuses will contain a break between their inner metal.
