Hey!

I want to flush the P/S fluid out of my 1992 Civic Si and I want to do it by disconnecting the return line and flushing it using the pump pressure. So I was expecting only one return line, but there are 2 of them :



And this is the only diagram I could find :



I am wondering what's the difference between line 17 (coming from the rack, then cooler, then reservoir) and line 29 (directly from the rack to the reservoir?

I'm not sure which one to disconnect to flush the system.

Thanks

 

Id say the top. Fluid sucked out the bottom, go through system, put back in through top.
unhook top. Cap off top port. Attach drain tube to unhooked tube. Fill up resevoir. Start car, watch reservoir.

 

THanks man!

Any other opinion?

 

I wouldn't start the engine, you will empty the PS fluid reservoir in a second. take the belt off and crank the pump over by hand.

 

I have seen this done many times, not a problem. But thanks for the input
