1. Thorough Cleaning:
* This is the most crucial step. Power steering fluid is often dark and makes it hard to see the source of the leak. Clean the entire power steering pump and surrounding components *thoroughly* with engine degreaser and a parts cleaner. Use a brush to get into crevices. Rinse well with water and let it dry completely. This will allow you to see where the fluid is originating from.
2. Visual Inspection (After Cleaning):
* Pump itself: Carefully examine the pump for leaks. Look at the shaft seal (where the pulley attaches), the pressure lines (where they connect to the pump), and the pump's casing for any cracks or seepage.
* Pressure lines: Check the connections at both ends of the high-pressure and low-pressure lines. Look for wetness, cracks, or loose fittings.
* Return line: Inspect the return line connection to the pump and the reservoir.
* Reservoir: Check the reservoir for cracks or leaks. Note that a leaking reservoir won't necessarily come from the pump itself, but could be the cause of fluid loss.
* Belt tensioner/pulley: Sometimes a failing tensioner or pulley can sling fluid that appears to be coming from the pump.
3. Run the Engine (briefly and cautiously):
* After cleaning, start the engine *only for a short time* and observe carefully. Have a helper watch the pump area while you keep an eye on the fluid level in the reservoir. *Do not run the engine for an extended period* with a known leak – this can quickly damage the pump and steering system.
4. Dye Test (If necessary):
* If you still cannot locate the leak, consider using a power steering fluid dye. Add it to the reservoir and run the engine briefly. The dye will highlight the leak under a UV light.
5. Consider these less common but possible sources:
* Worn or damaged power steering hoses: These can leak, and the fluid may run down and appear to come from the pump.
* Steering rack: Leaks in the steering rack can also look like a pump leak.
* Pressure switch: A leak from the pressure switch is possible, though less likely.
If you've tried all this and still cannot find the leak:
* Professional Assistance: It might be time to take your Camaro to a mechanic specializing in older vehicles or power steering systems. They have the experience and tools (like pressure testing) to diagnose the problem accurately.
Safety Precautions:
* Power steering fluid is corrosive. Wear gloves and eye protection when working with it.
* Work in a well-ventilated area.
* Dispose of used power steering fluid properly.
By following this methodical process, you should be able to isolate the source of your power steering pump leak. Remember to address the leak promptly to prevent more serious damage to your steering system.
