Help identifying this part
 

It is located on the firewall side of the motor just below the exhaust manifold. It is leaking coolant. I believe it is cracked. Any help would be greatly appreciated. Mine is not a truck it is a Avalon. But this was the only helpful looking forum for my motor.

Help identifying please

Wow. A really poor photograph in the (acknowledged) wrong forum.

Well, people on this site have come up with some pretty amazing answers at times. But I'll bet you'll get a lot more success if you give the Make/Model/year/engine of what you're looking at. And if you can't get a decent photo, fire up Microsoft Paint to at least point out the "it" you're talking about.

Or try it yourself. Pick one of the many dealer sites (I like https://parts.lakelandtoyota.com/) and enter your information there. You can find the exact part, including part number and price!
