Where do you check the power steering fluid? I think mine is leaking if it is reddish in color.

It could be air in the power steering system. Check the power steering reservoir to ensure it is properly serviced. If it is, check for any evidence of leaking under the car - power steering fluid is usually either clear or reddish color.
If you have to add fluid to get the reservoir back up to the correct level, it will take a little while to get air out of the system, so the hissing may continue for a period of time.

Need first locate power steering pump Power steering fluid leak color multi colored look for the right one if loosing power steering fluid need to check starting at the pump down to the steering rack to detect where the leak coming from hoses connections and all. Good Luck

Place a piece of white paper/cardboard on the ground below where the leak is coming from soon after the engine is turned off. This should help you locate where exactly the oil is dripping from, and should help identify what is leaking. If the oil is black/brown/gold, it's probably engine oil. If it's reddish/brown, it's probably transmission fluid. If it's clear, it may be brake fluid or power steering fluid (from the rack/pinion). Check the fluid levels for whatever you determine it may be. If it's engine oil, you may have leaking valve cover gaskets or a leaking rear seal on the engine. If it's transmission fluid, you may have bad transmission cooler lines or leaking from axle seals. Check the master cylinder and brake lines if it's brake fluid, and check the rack/pinion if it's power steering fluid.

If it's reddish then likely it's transmission fluid and if brown or black then engine oil. There are seal conditioners available that may help temporarily. You can try one but if the leak is not much and you can live with it; I would put a catch pan under the car at night and see what accumulates. If only a few drops a night or less then just check and add as needed. If there is a puddle, then check color, reddish - time to see the transmission guy. Black or Brown oil may be the engine is leaking oil. Reddish can also be a leaking power steering line so check power steering fluid level too.

That is transmission fluid or power steering fluid, get the leak looked at right away, it does pose a serious fire hazard if it blows back on the hot exhaust system, have many fires from theses types of leaks..

For many years a reddish colored fluid leak usually meant a transmission or power steering leak. But with all the multi-colored antifeezes on the market today, it's possible it could be antifreeze.
My advice is to check all three fluid levels. Whichever one is low will probably turn out to be the
system that is leaking.

i would remove the power steering cap, and look inside of the pump, and take the end of a screwdriver, and dip it into the pump, and bring it out and look at the color of the fluid, if it is clear, then it has power steering fluid, if it has a reddish looking color, then it is atf + 4 fluid, also , you can look into the owners manual of your vehicle, if you have the manual.

power steering does NOT have an overflow it will have to be taken out ps fluid is usually red or sometimes a yellowish color. if its clear i would check brake fluid

Yes. The fluid is also red for the Transmission on Ford products and some others. The color is to aid in leak detection, just as Antifeeze is colored to help spot leaks.

im quite sure this will be the power steering fluid leaking, IF the coolant level is staying full. check level of steering fluid its a reddish colour but can become pink when leaking and mixed with water etc. hope this helps
