power steering blockage

the pressure in the power steering system keeps blowing the return line off the rack.---my questions are----is there any check valves anywhere in the system also is there a screen in the reservoir----anyone know whats causing this? the truck is a 2002 tacoma 4x4 3400 engine--thank you

 

Is the return line clamped on good enough? Have you bled the system totally free of air? Is there anything between the return line from rack to reservoir?

 

There is a screen in the reservoir that gets blocked (remove it and put an in-line filter in) but enough to blow the return line, I think not

 

I thought all the fittings on the rack were threaded!?

 

texoma---i put 2 new clamps on both ends of return line at the rack---there is nothing between the rack and reservoir ---the line blew off twice while trying to fix it

 

It sounds like you may still have air in the system. Bleed it down with the engine off, keep the res cap off, then start it and cycle the rack back n forth. Before anything, check that line for blockage.

 

winslow939---the high pressure line is threaded but return is clamped-----i'll take out the screen ,see if it helps

 

98tacoma27----thanks for the diagram

 

98tacoma27----roger that and will connect a hose to the reservoir take cap off and blow though that

 

good diagram, should of figured soft lines from reservoir had to connect into rack hard lines somewhere, derr

with how many kinks there are in the return line, it might be good to give it a blast of air from a compressor if you have one, you might turn purple trying to blow air through yourself

 

oh, if your leaving it attached to reservoir, don't do compressed air, you'll have a power steering fluid party all over the engine bay. I meant if you disconnected the whole line and removed it from truck, then blow air through
