how would the heater core cause a leak that is coming from behind the power steering pump which is on the right side of the engine?

Hello,

This sounds like you have an intake manifold leak which would cause the leak you are describing. Here is a guide that will show you what you are in for when doing the job. Before you begin check the wee hole of the water pump just to be sure
