Hello, I am replacing an electrolytic capacitor 1000UF 25 V. I was wondering when I replace it do I get an electrolytic capacitor with higher voltage (ie 35 V) same capacitance or get a 2000UF with a voltage of 25 V?

If it's not a "Tuned-Filter", (like a Buck-Converter),
then larger on both Capacity, and Voltage, is usually better.
Physical size then starts to be the determining factor.

It depends on how the capacitor is being used. In some cases, a higher capacitance will be detrimental to circuit operation. Without analyzing the circuit, your best bet is to replace with the same capacitance at a higher voltage - assuming a larger physical footprint can be accommodated.
