Well I replaced my high pressure powersteering line with a 3SX performance line which deleted my IAC. I also replaced some return hose sections and put in a new reservoir. I filled the powersteering fluid up and turned steering wheel back ten times to try to remove air...got the noise down some...took the car for a drive and after a minute powersteering fluid started gushing out of the reservoir!

What did I do wrong with the filling process??? Correct filling procedure for 1993 sc400 is what? Could it be that I have a bad pump?

Thanks! after 4 months on this project changing everything from suspension to ignition parts 3 of the 4 months has been this dang power steering leak, any help appreciated.

Just tried fixing power steering again. I can get it to where it drives great and doesnt make a sound when I turn the wheel...then after driving 15 minutes it all leaks out of the top of the power steering fluid reservoir.

I would like to add that I am using dextron 4 automatic transmission fluid is that the right fluid? They dont make dex 3 anymore...seems strange to use automatic transmission fluid

Being hydraulic system there ought to be a pressure relief valve or check valve in the line. Take another look at service manual. Same thing happened once on my
camping trailer tow truck. Cause was bad pump assembly. I found a replacement at the wrecking yard.

A lot of folks on here have blocked off the idle air control valve without any problems...putting the AN line in there bypassed this...so your saying a bad pump can cause fluid to gush out of the reservoir?

Thanks Htony I think I should just change the pump and see if that works

Went through this drama myself. Replace the pump suction line from the reservoir. It could be sucking air, like mine. Save yourself some grief and use a OEM curved hose.
