Exclamation

the heater core lines go into the firewall on the left side of the engine if your standing infront of the car it is above the engine its self. and then comes out behind the engine. i think i know where your leak is coming from. the two valve covers. reach in between them and feel on the back of the engine thats where the coolant returns to the engine. feel around there mine leaked from there for the longest time before i could figure it out. like th epost before me. the hose clamps are old but you dont have to replace them until they leak those hoseclamps are good clamps. they dont clamp with alot of force but enough to do the job. now if your trying to get alot of hp out of the engine replace them with screw clamps. but check that you wont be able to see the line but you can feel it if you have small hands. a hose that is worn out or failing will be soft. not hard to the squeeze but soft like you have fold it 3 times. so check that and get back to me and see if i gave you any help
