Okay i'm on my second radiator in like 1000 miles. they keep leaking for some reason. Could it be that the system is under too much pressure? Do you think it would help switching to a less pressure cap? it is leaking out the side cans apparently.

 

Have your coolant checked for products of combustion. That's a common symptom of a blown head gasket.

 

Definitely a blown head gasket.
