What's this part?

Hello,

What is this part?

I pulled into my drive-way and saw a huge puddle of coolant under the engine. I found the source of the leak and it was coming from this part. What's it called?

Thanks,

Not a 100% but it looks to be part of your heater core?
To be honest i havn't seen something like that before, I would suggest getting under your car and seeing what's missing... and take another pic...

I'd say it's the "heater tap", which controls the coolant flow to/from the heater core.

heater taps breaking are pretty common. Do a search for 'heater tap' because there are lots of guides explaining how to replace them. I paid about 40 bucks for a new one from holden and fixed it about 30 minutes with no experience at all.

That's the worst looking heater tap corrosion I have ever seen (maybe I lead a sheltered life). Suggest you start running proper coolant instead of water or cheap coolant (which is mostly just coloured water with a little inhibitor thrown in).
