i replaced 3 to four radiators an keep getting them to over heat an leak from bottom passenger side . plus when i replace one the temp gauge is at half way with in few minutes an never did that since i had it

 

there is no way that you could have had that many bad radiators. There is some other problem. Watch Scotty Kilmer's YouTube video "How to fix an overheating car" and pray that it isn't a blown head gasket. He also has a video "How to tell if your head gasket is blown".

 

if you originally had it overheat it's possible the head is warped, try compression testing to see if the engine is in good condition

 

How are the radiator supports? What about the bushing in them? What makes you think its overheating?

Do you have auto or manual trans, and do you have an auto or manual radiator. By radiator an auto radiator has a lower portion for trans cooling so if you used it without hooking up the bottom portion you would have much less heat in the lower empty section of radiator possibly cracking a cheap part? Not saying they are cheap parts but I doubt you replaced 3-4 radiators OEM new every time
