My dad called me today and told me about leaking near the firewall/tranny of the car, he checked the hose's and the radiator and what not and none of the hoses seem to be leaking, I was poking around in here and wasn't quite sure what a heater core was and was curious as to if that could be what is causing the leak/problem. Is it possible to just have a hose go from the intake manifold to the waterpump to see if that solves the leak problem and drive without heat, to test the system?

 

if it was heater core, ud see a puddle inside the car on the passenger floor. check the weep hole on the waterpump after u drive it...check for moisture
