Like the title says ive got coolant leaking from the back of the motor somewhere i am not sure. Anyone have any ideas. Im thinkin it may be a freeze plug but i hope not. It only leaks after i have run the car for a little while then stops after the car cools off. Its running fine about 190-200 it doesnt overheat but i can smell coolant burning when im driving around its a chevy 350 its new i have only put about 300 miles on it since i put it in the car but i did sit for over a year after the rebuild before i put it in and ran oil thru it its bored 40 over. Hope you have an idea for me

 

might want to check the hose conenctions on the heater core.

 

Intake gasket could be leaking at the back corner?

 

I think it was the hose into the heater core. It was loose and a little wet around the bottom of it but i never saw anything leaking from it. It got dark but im gonna drive it and check again in the morning and see if that got it.

Yup that got it!!!
