Under the black rubber cap is a dip stick that you use to measure the fluid level. From my experience the level in your system is fine. I have changed my fluid a few times in the 200,000 miles I have run it, and there is a filter in the bottom of the plastic bottle you can change too. I bought a couple quarts of the the fluid, and aimed the return line to a 2 liter coke bottle, turned the car on, and then added new, clean stuff as the level dropped in the plastic bottle. I stopped when the stuff coming back from the system was nice and clear, like the new oil I was pouring in. Then I adjusted the level to the max mark on the dipstick and all was well. Hope this helps, Jim
