What you need.
New Power steering Pump.
Dex lll Transmission oil
New O Ring. Not sure on the size i had a pile laying around.
Socket set
Spanner set.
Screw Drivers for Hose Clamps.
Here we go.
Open Bonnet
Find Power steering pump here.
Loosen Bolts for the Pump pulley plate.
Remove Belt Shown Here.
Now Remove Bolts & Pulley Plate.
Here is the Power steering pump, Ewwies
Loosen Lower pressure Hose Clamp
Have a Container to catch the fluid shown here.
Now Pull the hose off and drain fluid.
Now Remove the 2 Mounting bolts shown here. Take note they are both different
Im Not sure if its possible to do this on other ecotecs, But move the Pump to the Side, Here you will find the High Pressure hose.
Word of warning though, This was a ultra B***H hose to remove, Its extremely tight ! I lost count on the amount of (- F(*#$*^%*(&$@*&)()%#!!!! - ) that were involved. In the End i had to get my father in-law to help, even then took us a good hour with power bars and vice grips. You may need to remove the Top radiator hose to give you more space.
Now after having a yelling match at the car, The Hose Is now removed, Throw it and yell some more.
Now here is your new PS Pump, Mmmm NEW!
Replace the O-Ring on the high pressure hose.
Screw the high pressure Hose into new Pump, Make sure its tight !
Now Mount the Pump back on. Replacing the 2 bolts.
Fill the Power steering pump up with fluid as much as possible.
Before Connecting the Lower pressure hose, Hold your finger over the Hose, Then fill the hose with fluid by pouring fluid into the fluid tank,Now quickly push it on to the pump, i did this to help remove air from the hose. Now clamp the hose on.
The Manual says to jack the front of the car up and turn the wheels left to right to help bleed the system, i did not have mine at the time, So i just turned the pump by hand for a good 10 mins to help push some air out. You will see some bubbles in the fluid tank.
Now the Pump is in, & All Hoses are connected, Attatch the pulley plate, Hand tighten bolts, replace belt. Now torque up the pulley plate bolts.
Make sure everything is connected, Checked 3 times to be sure.
Start the car for about 5 seconds then switch it off again. the fluid will foam, so let it sit 10 minutes, now top the fluid back up.
Start the car again for about 10-20 seconds while watching the fluid to make sure it dont run dry.
Allow to sit for another 10 mins, Top up again if needed.
You have now changed your Power steering pump, Now FFS go have a beer !
Hope this helps. Leave notes or tips if you want to
Cheers
