Hey everyone, first post here and a bit of a noob so please go easy on me.
I seem to have sprung a coolant leak in my 2002 Jeep Liberty 3.7L 4X4.
I was driving home when all of a sudden I hear the sound of sprinklers under the truck. Luckily it didn't overheat (temp gauge rose just slightly past normal mark) and I got it home in one piece.
When I checked the radiator reservoir it was entirely empty and it took about a gallon of coolant/water solution to get it back to normal. It seems my heater/coolant hose failed and there is a crack in the rubber hose. (I've attached an imgur link).
I also checked my oil cap for condensation/foam/signs of coolant in engine/ head gasket failure, all seems good there.
To test this I popped the hood and turned the car on this morning (radiator reservoir is still at the same level it was last night) and let it idle. No leaks.
Then I revved to about 1.5k RPM and coolant started spraying from the fault in the hose.
Now, I've only just started learning about cars and how to work on them so I'm not very confident in my diagnostic skills. I've spent all night looking through parts manuals and I think it's the heater hose / coolant hose where it attaches to the water pump(?). My theory is that as I accelerate, the water pump pulley works faster, and more forcefully moves water through the cracked hose thus resulting in coolant spray everywhere.
My questions are:
1.) What is this part? (Link to pictures included) Is this actually the heater hose / coolant hose?
2.) Where do I find replacement? Is it a specific OEM part or can I find a generic synthetic rubber hose at a parts store?
TL;DR: My car sprung a coolant leak and I'm not sure what this part is. What do?
