The radiator holds violent but after I drive it and the engine worms up I start leeking cooling by the pass side radeator at the bottom by the lower rad hose could it be a cracked radiator or bad hose thanks

 

verify where it is coming from. If it is just the hose, you could try just pulling those hose, cleaning things off, and see if that doesn't fix it. If it is the radiator itself leaking, replace it.

When the engine warms up, it builds pressure in the cooling system, so, while it may not leak when cold (no pressure...), when its warm, it opens up the hole a bit. (pressurized.)
