Can I use a higher voltage rating when replacing capacitors?
My question is this: When it comes to replacing caps, you can go to a higher voltage rated cap but have to stick to the same farad rating? The bad caps are both 6.3 V, 4700 µF and i was thinking of replacing them with 16 V, 4700 µF but getting the better quality 105 °C rated one as the others ones are 85 °C rated.

6 FAQs about [Voltage of the autocapacitor]
How do automotive capacitors regulate voltage?
Regulating voltage: automotive capacitors regulate voltage by shifting it between two rails—one for high current applications like lights and gauges on dashboards or instruments on dashboards themselves (such as tachometers), and another rail for low current applications such as headlights/brake lights/hazard lights/turn signalsthe list goes on!
What is a capacitor voltage rating?
The voltage rating is the maximum voltage that a capacitor is meant to be exposed to and can store. Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it.
Can a capacitor charge up to 50 volts?
A capacitor may have a 50-volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a DC power source. The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to.
What do you need to know about automotive capacitors?
All you need to know about automotive capacitors. Capacitors are an essential part of any vehicle’s electrical system. They perform a number of functions, including smoothing out the flow of electricity and reducing voltage drops.
Should a capacitor be rated 50 volts?
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor).
Why do capacitors have different voltage ratings?
In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.
