- 48. This brake fluid reservoir will look different in each car, but the premise is still the same. The line level will show you if you’re needing to add more fluid, or if you’re fluid is the wrong color.
- 49. This is just an example of a coolant reservoir. You can see the two notches on the side as indicators of your coolant level. If your engine is hot, you won’t get an accurate reading- and you’ll probably burn your face or hands off. (okay, not completely off, but it will hurt!)
- 50. This is an example of a power steering reservoir, and while most cars won’t look exactly like this- you can still see the min and max line indicators. You should rarely need to replace/fill your power steering fluid. Even some car manuals say you never have to replace it- but a good judge is the fluid’s color!
