Pwr steering pump failure GM truck

Pump seals failed a week ago and all fluid lost and bearing went. Installed new pump a week ago, all was well for a week. Same seal failure and all fluid lost coating everthing around pump and pump seems overheated while covered in fluid and smoking. Why would a new pump seem to build up too much pressure and fail?

What does it mean when my 2010 camaro has no power steering


2010 Camaro Power Steering Failure

It means the power steering pump is no longer operating and so providing the required power assistance.
You either have a power steering fluid leak in the system and much of the fluid has been lost or the power steering pump itself has failed. You should not try and drive the car when you have this problem because the steering will be far too heavy to drive safely and because if a fluid leak has run the pump nearly dry you will cause damage to the PS pump.

The first thing to do is check the power steering fluid reservoir in the engine compartment. If it is low or empty you have a leak in the system. You can refill the system with new fluid but it will continue to leak until the leak is addressed and you will have to constantly add new PS fluid. In the case of a major leak the car will not be driveable as the PS fluid will be lost very rapidly. Without fluid you will quickly ruin the pump and you will also have no power assistance in your steering.

Power steering went out after hearing poop in front end while in reverse with a car in tow on a tow dolly. Pump is full of fluid and not leaking and I can't see any obvious damage under vehicle. Help?!


the dealer has some recall issues with the steering shaft.
Sounds to me like the pump itself took a dump.
contact any chevy/GM dealership, ask for a service advisor and ask him if there are any recalls for your vehicle. (have VIN # handy)

When driven about 10 miles, makes a noise similar to a power steering pump going out, but only when it heats up, power steering fluid is full. Why would it only make the noise when engine is hot?


The Power Steering Pump has a Fluid Cooler, a small radiator located on the bottom of the Van. It is used to cool the power steering fluid off. If there is a blockage problem this will cause overheating.
Although there is fluid, when was the fluid last changed? Then was the last time this entire System was flushed?
However, the Power Steering Pump making noise only when heated is a definite beginning sign that Power Steering Pump Bearings are failing. When these fail, they do so without too much warning, meaning Noise and then failure immediately after!
Before you run out and buy a new Power Steerin Pump, make sure it is in fact the Pump and not the nearby Pulley's or Pump's. Some people rush to judgement and change out the Pump when the nearby pulley bearing was the real culprit.
Let me know if this helped. or if you have additional information or questions. Feel free to contact me at FixYa.com!

You probably lost the shaft bearing and seal in the pump. Replace the pump as it probably has damaged internal parts as well. Is this an engine driven fan or an electric one? If the engine tossed the belt during this event, it may have caused the fan to become damaged. If an electric fan, the shaft may be bent--replace the motor. If engine driven fan, you will need to disassemble it to find it's problem. Inspect the drive belt(s) for wear or damage. Recheck for proper cooling action after everything is back together.

Power steering lacking at parking and slow turns


It is possible that the pump is failing...even though it is quiet. It could also be that the steering rack inner seals have lost their effectiveness. When the fluid heats up, it gets thinner, and it is more likely to leak past worn seals, which you undoubted have somewhere. But after 300,000 miles...you can't complain to GM. Those cars are about as bullet proof as they come. Good luck.
