Yes, you can tighten the seatbelt return spring, but it typically requires disassembling the seatbelt mechanism, which can be complex and may vary by vehicle model. It's important to ensure that any adjustments do not compromise the safety features of the seatbelt system. If you're not experienced with such repairs, it's best to consult a professional or refer to the vehicle's service manual for guidance.

Not sure what you are talking about. If you are referring to a part in the engine then the piston does not have a return spring. If you are referring to the piston, not quit the right term, in the brake area then in the wheels the there is a spring and in the actuator there is a spring. No other item I have ever heard of as a piston return spring. Can you elaborate?

You don't "tighten" the belt, it's self adjusting. If the belt is slipping you probably have a problem with the tensioner spring. Occasionally the spring weakens over time. Pull the tensioner and replace it if you think it's loose.
the belt is automatically tensioned by a spring loaded tensioner.
The belt has an automatic spring tensioner and can not be "tightened".
first the spring puts tension on the belt, then you tighten the tensioner assembly and it hold there.
