There are some instances where replacing electrolytic capacitors may not be necessary. There is a difference between a "bad" capacitor and one that has drifted out of spec. Reforming is a complicated subject, with sometimes strong opinions both for and against.
Trim the leads of the new capacitor so that they are both even, and will sit at about the same height as the old capacitor. Position the new capacitor leads at the holes where the old capacitor was, with the correct polarity. Just like before, press the tip of the soldering iron directly onto the joint in the back of the circuit board.
Reforming Electrolytic Capacitors The process of reforming an old aluminum electrolytic capacitor consists of the application of rated voltage, through a resistor, for a period equal to five minutes plus one minute per month of storage. The electrolytics appearing on the surplus market have often been in storage for a very long period indeed.
Shorted/failed capacitors can also cause other parts to fail, leading to further repair needs. If there are any visible signs of failure of a capacitor (leaks, etc) you should replace it; reforming will not fix those problems. Reforming is a preventative measure to potentially reverse natural deterioration in the capacitor.
[Dexter] undertook a repair of some four-decade-old capacitors in a power supply. He didn’t replace them. He fixed the actual capacitors. The reason these units are prone to fail is the flip side of what people like about electrolytics: high capacitance in a small package.
