Help identifying source of leak

[Pfeiffs84]

Hi,

First up a disclaimer: I've never been particularly mechanically minded, but I'm learning (mostly to try and avoid being scammed out of $$$ by unscrupulous mechanics...).

I have a VZ SS 6.0L Ute which has a leak towards the back of the engine bay - I'm fairly certain it's just water and not coolant, so hoping it's just related to the A/C. It's coming from this small yellow plug:



What is it, and is it something to be concerned about?

I've been battling various coolant leaks for the last little while so I'm a bit gun shy the second there's any leaks. I've had mechanics tell me there's a fair bit that needs doing on it but I'm keen to sell it so battling between getting them quoted and fixed, or just selling as is.

Any advice appreciated.

That is the Evaporator Drain from the HVAC,

And is normal to drain condensation out of the HVAC system.

Assuming it looks like water, and doesn't smell.

Great! That's a relief - definitely looks and smells like water.

Thanks for the response!
