Re: how to get the tension off timing belt for...
Usually there is a idler that can be "unsprung" with a 1/2 drive ratcher, look for the square drive hole and turn in the direction that would relieve tension. there may also be a bolt that tensions the idler, loosen bolt. My Plymouth had a hydraulic (sort of) tensioner. It was a small piece that had a pin coming out the bottom that acted on an idler. You unbolt the piece and the tension would relax. To install, you had to chuck it in a vice and turn the vice slowly to push the pin in against a VERY heavy spring, then you put a small drill bit in a keeper hole to keep it retracted, bolt it in and pull the pin and it would expand putting tension on the idler.

I found this picture, it didn't say northstar. The tensioner in picture has a half-inch cut-out. Use a 1/2 rachet or break-over in cut-out, usually the longer the handle, the better. You pull the tensioner one way or the other to get slack in the belt, then remove belt from accessory pulley.
The fan belt is probly worn or dirty. Try cleaning the underside or the pullys in the serpintine route............or u mite hav to go back and chec work on the timing belt is all torqued to specs. Is belt tension rite
Tensioners can have the pulley or ride wheel replaced or you can replace the entire tensioner. But if your belt hasnt been replaced in a long period of time it might be time for a belt replacement. A tensioner has a limited amount of travel to use to keep tension on the belt. Once the belt has stressed and stretched to a long enough length then the tensioner cannot apply any more tension.

You need to get a manual. Try the Haynes manual for your car. Try autozone; generally available for around $20. This is not the type of thing that can be covered here in enough detail to do you any good. You need a picture. Buy new timing belt. Disconnect negative battery cable. Remove timing belt cover. make sure cylinder #1 is set at TDC. making sure all components are properly aligned and loosen pensioner to remove old timing belt. Install new timing belt. Tension belt, ensure all components are aligned properly, replace timing belt covers and reconnect battery.
you're not giving me much to go on,but I'll guess it's the 'serpentine belt tensioner pulley' identified by the 'arm 'it was attached to being spring loaded to maintain belt tension.replacements are available.check belt condition while you're at it.
If your tensioner will not release pressure then you will require a new tensioner. These units do loose the ability to apply proper tension and they fatigue over time. Also, make sure that the belt you have is the proper length.
you will probably find it is infact the hose or hoses that have deteriated and leaking and not the housing. A bit on the aukward side but relatively simple to chang them. I used new car heater hose instead of the specified replacement hydrolic pipes from toyota and saved around £150!!! just follow the connections of the pipes and take off and replace. If however it is the pump housing loosen off the tensioning belt by undoing the tention pully bolt take off the belt and undo the mounting bolts attatched to the housing and simply lift it off. Either get the housing repaired or replace and refit bolts and tension the belt and tighten up the tension pulley bolts.
