1996 honda accord after changing the power steering belt and run the eng, the power steering reservor is over flowing and lots of bubbes. and loud noise every time you turn to lt and rt .the lines was never disconnected or unhook. the belt is tight and secured . we just replace the belt.

It sounds as if you have a volume of air in your power steering system. This is causing the bubbling and also some of the noise you might be generating when you turn the wheels hard right or hard left. This air might have been introduced if your old belt was slipping so much that the pump was essentially not operating and fluid wasn't regularly circulating throughout the system. Another, more expensive possibility is that your old belt was slipping because the power steering pump itself was starting to fail, and the new, grippier belt is turning the damaged pump and showing you its lack of functionality.
The first and easiest thing to do would be to bleed the system. Open the hood and take the cover of the power steering fluid reservoir. With the engine off but the steering wheel unlocked, slowly turn the steering wheel all the way to one side and then to the other. Repeat this several times while watching the power steering reservoir. Is the fluid bubbling? If so, good, you're purging air out of your system. In general, this is easier with the front wheels off the ground, but that is not absolutely necessary (if you have strong arms).
Once you have purged the system, put the cap back on the power steering reservoir, topping it off if the fluid level has dropped to the fill mark. Now, restart your car and observe the power steering pump. Does it seem to be operating quietly and smoothly? If you touch the pump 1-2 minutes after the engine has been running, is it hot to the touch? It will probably be warm, but _hot_ is an indication that something is overheating inside the pump. Is the power steering fluid very dark colored or does it smell burned? This is also a sign that the fluid should be changed ASAP and that some internal damage may have occurred. Burned fluid isn't necessarily an indication that your power steering pump is bad. However, if after changing your PS fluid the new fluid quickly becomes dark and starts smelling burned, then it's probably time to start saving money for a new or rebuilt power steering pump.

Air in system

Air is getting into the fluid. This is usually from a bad o-ring on the pump where the return hose from the reservoir connects, or the hose from the reservoir to the pump has been disturbed, and letting air in past the clamp, this is common on older Hondas, and Acuras, the hose has gotten hard with age, and once "disturbed", no longer seals. Replace that hose and the o-ring. The hose is only available from Honda, I believe. While there get Honda power steering fluid.
