Alright I replaced my heater core about 8 months ago, and never had a problem.

I recently took the throttle body off and the intake manifold.
Put on a carburater Edelbrock performer RPM intake, and a Edelbrock 750cfm carb.

After I did this found out I had a coolant leak somewhere.

Now I found out where it is coming from. Threw some water in it, and got a hose leaking water...

This is the hose that is coming from like 3 different ones at the top of my motor. And the hose shoots down. I got the hoses on my heater core hooked up, but I cant figure out where this one goes, and it looked like it ripped, and poped off somewhere. But again I dont see where it goes...

So I wedged a screwdriver in there and put it in place with a clamp.
On the drive home I saw that the thermostat kept getting higher. went from 100 to 200 within a 6 block radius...

so where the hell does this go???
