Little elbow piece coming off the engine block above water pump going into looks like ALT bracer?

That sounds like you're describing a tensioner bracket or possibly a part of the alternator mounting bracket. It's a small component, often made of metal, that helps support and position the alternator belt tensioner. It's located near the water pump and engine block, often with a connection point for the alternator.

Because it's "coming off," it's likely broken or loose. Do not attempt to operate the vehicle until this is repaired. A broken or loose bracket can cause the alternator belt to come off, leading to alternator failure and potentially other serious problems.

You should take your vehicle to a mechanic for proper diagnosis and repair. Describing it as a "little elbow piece" isn't precise enough for them to know exactly what part it is, but they'll be able to identify it upon inspection. Bring photos if you can.
