I have this small leak i see couple drops every week, I'm not sure if I need to concern at this point. Can someone tell where this leak coming from? Can it be a DIY fixed? Please see the picture.
Thanks.

Are we looking at the underside of the radiator? Is that where the leak seems to be dripping from?

That looks more like a brace. You need to first identify what type of fluid it is. Engine oil, power steering-transmission or coolant. Fluid leaks blow around so they aren't always easy to locate. Some shops use dye to locate.

My guess is - it's power streering as it is not coming from transmission pan or transmission fluid cooler lines. Power steering fluid can be verified by checking the fluid in the canister to see if level is correct. You can clean the underside with oil degreaser and then trace where the leak is coming from. Good luck and keep us posted.

Good advice regarding the need to identify the fluid.

Looks like the brace located between the engine and transmission.

If I remember well this is where I saw engine oil dripping as a result of the camshaft plug leak. If this proves to be the source of your leak then this issue has been discussed on here before. The parts are cheap and it's certainly a DIY for most capable home mechanics. Of course, if you're under warranty or CPO the dealer will do this at no charge.
