Help....what just happened?

I'm backing out of a parking spot, hear a pop and have no power steering...belts are fine and no other noises. Fluids are good as well. So whatever, figured the pump is done. So then, I have the car on looking at the belts, checking for anything else, get back in the car and the temp gauge is up...now looking at the car very confused. Any ideas? I need to get this out of this parking lot asap

Are you sure the belts are okay?

If the power steering is gone and the car is overheating, then the commonality is the main belt has broken. Turn the car off and yank on the belt.

That's my thought exactly but they're perfectly in tact and all pulleys are spinning fine. No odd noises or anything.

Temp gauge is up as in overheated?

So your wheels will turn, it's just very hard?

Pull the belt and check the water pump and the power steering pump pulleys. My bet is that you water pump is seized and your ps pump is shot. Check the ps pump by seeing if you can pull the pulley forwards or backwards in and out of the pump.

Yeah needle was 3/4 the way in the red. And wheels do turn, just no power steering..

Water pump only has 10k on it.
PS pump pulley isn't loose at all.

It is very, very unlikely that both an overheating issue and a PS issue would happen at the same time unless there is an issue with the belt itself.

You have to take the belt off and turn all of the pulleys. You are describing a main belt breakage, but you also insist that the belt is moving. You have to take the belt off and check that the various pulleys all turn properly.

+1. Taking the belt off should uncover the problem.

Agreed.

I don't see how this could happen without a belt breaking or having multiple pulleys seized.

Is your water pump spinning?

Exactly why I'm completely mind blown.

I hope this could be an issue, is there a power steering cooler than runs through the coolant in anyway that could have busted putting power steering fluid in the coolant or anything of that such? I remember something along those lines happening to my buddy's Audi.
If that's even possible. He's not the brightest one.

No. There's a heat exchanger for auto trans fluid, but no connection with the PS fluid.

I already got picked up by a friend. To my eye, with the car running everything was functioning perfectly fine. All pulleys were spinning that I could see and the belts were fine.
Unfortunately my father just left for Iraq Monday and he has more knowledge over all of this than I do.
I agree entirely with you guys that it sounds like a main belt breakage or seized something or other, but I can't do much with it in the parking lot there. I'll get it to the hobby shop on base as soon as I can.
Thanks everyone who has responded. I'll be back there tomorrow to get it somewhere..

That's odd to say the least.

You're telling me..I'm super confused. Hopefully when I get a better look at it I'll be able to figure something out or update you guys. For now, research time.
I'm definitely going to double check all the belts and everything.
I thought the water pump and power steering were on separate belts?
I can motor swap a 350 crate into my jeep by myself but when little things like this happen it makes me so mad not to know what's going on.
Keep in mind that I'm only 18 and still learning, so I'm taking all your words and troubleshooting into consideration. I just got into the German world a year ago and glad to say this is my first problem!

No. The main belt drives the alternator, power steering, water pump. The other belt only has the AC compressor on it. The waterpump is the large, top, center, puller underneath the thermostat.

Hey guys, just a little update.
Replaced the power steering pump today, the shaft was completely broken and the pulley was just spinning free..so that fixed that.
The overheating issue I'm starting to believe is my electric fan is failing cause the temp gauge only rises when idling after its at running temp. If it idles for like, 5 minutes it starts to overheat and as soon as I start driving it goes back down..any other ideas?

its most likely your fan then if it only starts to overheat while your at idle... my last e46 did the same, the electric fan was shot.

Busted PS pump shaft?
