Gts-t P/s Pump Swap To Gts-4

[GTS4dood]

Morning all,

I've been living months and months with about 1 minute of driving with power steering before it cuts out. When the car is just switched on it works fine but then just dies. I was planning on just getting a new power steering pump. I'm also thinking of getting rid of the Hicas. GTS-4's use a dual pump for Power steering and the hicas...so if I put the hicas lock bar in, remove all the hydraulic lines and solenoids, all the way to the power steering pump....would i be able to replace my dual pump with a normal, single GTS-t pump????

Cheers!

Quick question, how do you know it is the pump? Regularly failing like that after start it sounds like the failsafe condition where the steering goes hard when there is a fault with the control system.

Have you completed a hicas diagnostic? What did it show? (If you didn't know the hicas and power steering control systems are combinedin the one controller, a problem in either system will cause this symptom).

I havent ran a diagnostic, i just dropped it off at the local import mechanic months ago and he said he couldnt find the problem and to buy a new pump. I'll give the diagnostic a go and see what i come up with.

Cheers!

The gtst also uses the twin pump.

You'd want a gts pump and you will also need the bracket and lines.

They use a 3 rib pulley instead of a 4 rib but you probably wouldn't need to change the crank pulley so it might not be an issue.

I doubt it's your pump, more like solenoid control.

Could be speed sensor or other input to hicas computer.

I wouldnt think it would be the pump either, when removing my hicas with a lock bar i used the standard power steering pump. You have to take the back cover off it and remove the vane/fan out of it so it cant pump fluid. Put the cover back on and block the 2 outlets with bungs, i just used the power steer fittings cut short and welded so they wouldnt leak.
