Left hand side of the water pump/engine housing block level with top of frame rail, 1/8 inch steam that sprays when running, leaks when not.

What is your best diagnosis?

Hi and thanks for using 2CarPros.com.

That could be a few things. First, if I had to take a guess, it sounds like it could be a heater hose. However, you really need to pressurize the system and then you will be able to locate the leak. Here is a link that discusses how to find and repair different types of coolant leaks:

See if that helps and let me know. If you find the leak or not and need additional help, let me know.

Take care,
Joe
