hicas removal

just wondering is there a way 2 remove the rear hicas solenoid, should i unplug it?

also whats the best way 2 bleed the ps system, my steering is very heavy after the TT pump mod

 

you've undone the 3 nuts that's holding the rear solenoid on so you should just be able to yank it off now simmo....

 

is there any point though ?

 

weight reduction!

 

wooo weight reduction FTW

im starting this today. should be interesting

 

Dont you need a HICAS lock kit? Cos if you just go yanking it out you lose your power steering

 

BLEEDING

Jack the front end of the car up in the air, put it on stands.

Turn it on, go between full lock Left and Right, a number of times.

Check fluid . add if nessary. and yeah.. just keep working it untill you feel its right.

 

thanks fellas, i gave the unit some "tough love" and she popped out, now i just need 2 sort my steering out or im gonna have arms like popeye

 

ok well ive done that about 10 times now. steering is still really heavcy, there are no ps leaks anywhere. whats the go.. is there such a thing as Hicas safe mode?

 

Yes. If the HICAS detects an error it goes into a safe mode where the steering is heavy at all speeds.

 

ok so how do i trick it or disable that feature?

 

bump bump.. anyone? surely some1 else has de-vaned the TT pump

 

you didn't de-vane your pump. the thing you removed is some type of valve. the vanes are small rectangular bits of metal that are located around the impeller. either way im not sure that this is whats causing your heavy steering

 

hmm ok . well i have followed the tech article provided by wok burner.
anyone else suffering the same issues?

 

I have suffered no ill affects since removing the hicas. I didn't de-vane the pump,
simply plugged the redundant outlet at the pump. My steering feels the same as it did before the
removal, definately not to heavy. Perhaps your pump is not building enough pressure?
It may have a damaged vane and is allowing some internal bleeding?

 

interesting. i was veary carefull with the pump so i doubt i damaged it

THIS SUCKS.. SOME1 HELP

 

Can you re-assemble your pump, before the removal of valve (wokburners tech) to it's original state?
If so, do this and test to see if the steering returns to normal operation. I used the
banjo bolt with a tubular sleeve to cover the exposed outlet in the bolt, fitted copper washers
to both ends of the sleeve and bolted it to the hicas-out on the pump to seal it up.

 

i guess i could but pump is in the car atm.. are u saying take the pump appart, reinsert check valve and spring and just block that pipe off?

 

Yep.
