Is it possible to replace the heater core without removing the dash? Can you give me the basic steps to go thru?

Hello,

In order to remove the heater core, you will have to remove components from the bottom of the dash. That is the only way to access it.

Before taking out the heater core you want to first drain the coolant and remove the heater hoses from the fire wall.

Here is a helpful guide:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
