Re: power steering filler cap leaks
Get a new power steering reservoir. They don't run to much and they are easy enough to install. You can't let it run out or you will most likely do damage to the pump, then you'd be looking at some $. So just fix it while its reasonably easy and save yourself headaches later. GHope I could be of some help.

With the engine cold, loosen the steering reservoir filler cap to allow air into tank. Take the lowest fitting loose and let it drain into a bucket under the vehicle. When finished draining remove Line fitting at reservoir. Remove any brackets holding the line in place and remove line from vehicle. Take the line to automotive supply and buy proper replacement using old line to verify fit. Purchase enough recommended power steering fluid to replace what drained into bucket. Install new line in reverse of removal steps making sure seals (washers and/or "O" rings) are properly installed. Dispose of old fluid safely.
To fill reservoir and line: While filling reservoir with engine running turn steering wheel from left to right until wheel stops. Continue filling and turning until all air is out of system and reservoir is at the proper fill level. Check for leaks.
Buy the fluid at Autozone and ask them to add for you. Usually they will and show you where the fill port is. Power steering fluid should be replaced every 75K miles. Usually you can buy an inexpensive turkey baster and use it to remove old power steering fluid from the reservoir and replace it, (always use synthetic transmission fluid vs non synthetic) I find using about an ounce or two of Z-max transmission treatment added to the fluid extends pump life.
Check power steering fluid, should be clean and clear, if it's cloudy or milky, then water has contaminated it, which will make it harder to steer., especially in cold weather. Check filler cap for small leak which will allow water to enter. Check front tires for low inflation, which will also make it hard to steer..
to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.

The power steering filler cap is on the passenger side just behind and under the alternator (I had to use a flashlight to find mine but it's visible if you lean over the front fender - passenger side). . There is a cross brace by the firewall that I had to remove so I could get to the filler cap. The cross brace is held on by 4 nuts - 1/2" or 13mm - and removing them and the brace allows fairly easy access to the filler cap. Remove the cap and fill. I'd recommend using a small funnel since it's virtually impossible to get the power steering fluid bottle behind the alternator and around several hoses. A funnel made it a cinch. Check to be sure you don't over fill, replace the cross brace and you're finished.
