I have a coolant leak about the size of a brake line, that runs from head to head, in the top front of the engine.

I cannot find it online and it is leaking too bad to take it anywhere.

If I could just get the correct name.

It looks like it is coming out of the water pump gasket. You must start by draining the coolant.

Here is a guide and some diagrams (below) to help you get the problem fixed:

and you will need to take the fan clutch off.

Below are some diagrams on how it is on your car.

Here is a pump on Amazon for $91.00:

Please let us know what happens and upload pictures or videos of the problem.
