so i just got the rack and pinion replaced, but now after i got it replaced (didn't do it before) sometimes the power steering light comes on and i lose the power steering.
does anyone know what could be wrong?

 

Clean the -search- next to the coolant overflow pipe, you might want to solder them to make sure. Also, reset the VRAM by pressing the -search- 20 times. You can do the wheel calibration by moving the steering wheel, Clockwise first then counter-clockwise, or the other way around, not sure but I've seen it on previous topics, search and you should find it.

search1: power steering connector
search2: break
search3: clockwise then clockwise

 

You need to remove your coolant reservoir and access these wires in the picture below. The connections for the EPS is on the right with the three wires, clean it up for a solid connectivity; at times when your engine heats up it will cause the coolant fluid to flow out of the overflow hose connected near the radiator cap. Be careful when you remove the hose from the nipple of the radiator, it gets frail as the car age and will break and fray like seen in my pictures.
