Best to use a pressure rated line. A decent hydraulic hose shop will set you up with the right type with fittings.

I ordred hicas lock from japan already. At the moment i cant take out the whole hicas system, i just wanna put on the Hicas lock bar and loop the lines if its alright, im not sure looping the lines is a good idea or not. If there is something else easier can someone edit the pic and post another idea please.

If it was the Tomei one you disconnect the solenoid valve which (I surmise) stops fluid being pumped tot he rear steering rack in any case. |

I will attact a picture so you guys know exactly what im talking about. thanks By looping the oil flow at the rear, you will require high pressure fittings as the solenoids ensure sufficient pressure to move ther rack is availabe at the rear. A better (easier and cheaper) solution is to do the looping at the front. Straight out of the power steering pump (rear stage) into the power steering cooler and back into the reservoir. I will mark up the schematic tonight, but I can't see the power stering cooler mentioned, maybe becaase it's just a loop of aluminium pipe they don't put it on the schematic. cheers -------------------- I don't own or work for a workshop and I don't know everything.

I have marked up the HICAS schematic;
The Blue dot is the power steering cooler The Red dots should be joined together, this bypasses the HICAS solenoids completely.  No cutting of pipes required, around those locations you will find the steel pipework has clamped rubber hose sections, just remove the (short) hoses and substitute them with the new (longer) piece of joining hose. If you are not removing the rest of the HICAs system, then block off the (no longer used) hoses to keep the crap out. There will be power steeing fluid trapped in the hoses, so make sure the capping is liquid proof. cheeers -------------------- I don't own or work for a workshop and I don't know everything.

It shows the cooling loop forward of the solenoid valve. As a aside since having my HICAS locked out with the Tomei kit the power steering fluid doesn't get as hot as it once did. This may just be from not being pushed through small orifices in the valves and/or steering rack but is probably also due to the cooler. |

Alright so i have finally removed my hicas about a month ago. I herd that you can unplug the HICAS ecu and the light on the cluster will stay off and the steering gets a little heavier, is that bad for the power steering pump? Is it better the leave the HICAS ecu plugg IN or OUT?
