Angry Power Steering Fluid Gushing Out!!

Help guys, my power steering in my 7 without warning failed. After investigating the problem, looking for leaks etc, it was determined that the fluid was gushing out of the reservoir. I thought it was overfilled, but it doesn't matter how much is in there. As soon as I start the car it shoots out like a geyser!! Any thoughts?

Additional Info: When I stated it gushes out like a geyser, I should of mention with the reservoir cap off. With the cap on it leaks from the cap. Question : with the cap off an everything working properly shouldn't you see the fluid recirculating in the reservoir?

I've seen a few cases where the filter in the reservoir becomes blocked, causing a pressure buildup on the return side and a vacuum on the suction side of the filter. Fluid sprays out as a result. Replace the reservoir and flush the system.

I don't believe they offer a reservoir for the E65 or any vehicle with dynamic drive. There is a level sensor on the bottom of the reservoir of dynamic drive vehicles. If the fluid is low or the sensor disconnected the system goes in a failsafe.

There are only two types, angled or straight. The e65 has the straight tips

Yes, like I said they do not list a compatible reservoir for E65 or any vehicle with dynamic drive. The ARS control unit uses the reservoir level sensor as an input. It would send the system into a failsafe.

Replace the reservoir with a factory unit, flush the system, if you still have issues you will need a pump. The tandem dynamic drive pumps are not cheap.

Thanks, had it on the lift yesterday, no leaks, looks like something going on with the reservoir. Meangreen94z you mentioned filter going bad, can I replace filter in this reservoir??
