My guess is heater core is leaking. The only quick fix is to bypass the heater core. You won't have any heat then. Look at the firewall under the hood. You'll see two hoses that run into the firewall going to your core. You pull them off the firewall and join them together using like a piece of 1/2" copper & some clamps. Whatever the inside diameter of the hoses are.
