Just checked my power steering fluid pevel and low and behold almost dry.
When i bought the car it was low but not to bad forgot about it though.
Just thought could i have done any major damage to the power steering system or just refilling should be ok and not manifest any problems. I havent noticed anything unusual so i doubt it just wanna make sure. Also stupid question what type of fluid and best brand etc?
Also another quick one its a tj ralliart but the build numbers missing any way to find out what number it is ?
Cheers

Fill it up and it should be ok. If you notice Amy squeaks or squeals then that's a new problem. If your ralliart build plate has gone you might be able to get Mitsubishi to tell you off the vin number.

If I fill it up will problems pop up dont see how and what brand type to use etc?
Nulon make a power steering fluid with "stop leak formula" - that's what I'd use because you must have a small leak somewhere in the system.

looked in supercheap and looked in nulon book says to use synthetic atf fluid i was confused as was going to buy the nulon power steering fluid stop leak stuff, asked the guy who did the transmission on my old car and said to use atf fluid as long as it says sp 2 or 3 . Read a post says never use sp 2 or 3 , im confused im inclined to believe the guy as hes worked on magnas for a long time . Little help
Ask 10 people and you'll probably get 7 different answers and all are probably correct but biased. I've used the stop leak fluid in many cars and have never had a bad experience so I'm biased towards stop leak - in your case you must have a leak otherwise the fluid level should not have dropped, so it seems to make sense to use a stop leak fluid OR reco the PS pump and rack for about $500 and a few days off the road.
Adding synthetic fluid or sp 2 or 3 or Dex 2 or 3 will top the system up but not stop the leak. Go to the Nulon website and see what they say there:http://www.nulon.com.au/products/Power_Steering_Fluids/#.T4ebEtXThEO
Good Luck.

Just bought some synthetic atf fluid its red color nulon however the stuff in the reservior in yellow gold color. Can I just mix the two or should I drain and or flush it. Its at min and no noticeable problems so not too concerned. How do you drain the power steering fluid and should I flush it and how to do that . Sorry im a bit of a mech noob just dont want to go doing stuff I dont know as the workshop manuels pretty vague.
If you want to just top up then just add the new fluid as they will all be compatible unless otherwise stated on the bottle. If you did want to drain the power steering fluid, the only simple way to do it is the get hold of a large syringe (100ML) and suck all the fluid from the reservoir, top up with new fluid, drive around the block for 5 minutes, syringe fluid out again and repeat this sequence till the fluid colour is the same as your new fluid. This method avoids getting air in the system and is foolproof.
One reason why the new fluid is red is to allow you to see when the old (yellow) fluid is replaced. It's the same with brake fluids where you should flush with a fluid that has a different colour to the old one so you know when the new fluid has passed through the system.

PS/ATF oil changes colour with heat, if your fluid was running at say 100°C it would stay red, once over approx 130°C it starts to discolour. Years ago i used to work for a OE steering manufacturer, we did normal testing of steering systems at 120°C and a hi temp test at 140°C, after running the 140°C tests the oil would be discoloured from red to yellow/orange

That's a good post - I never knew that ATF changed colour with heat so that is handy to know. Did a search and see that Subaru say the ATF needs changing if changed colour from red. I wonder if the dye in the ATF is designed to act that way?
