Are you saying the light comes on even when the temp gauge is low like when you first start it?

when i first start it, it takes about 5 min then the car will start to run hot and the light comes on. i can see the smoke coming from the engine, then then guage goes down but it still runs hot.

Assuming it is full of coolant, it sounds like you may have a blown head gasket from the previous leak if it got hot. There is a test most shops can do to quickly test for a blown head gasket.

so its not the fan, cause the fan looks kind of bad as well.

and how do i get a blown head gasket, did that come from the hole in the radiator when i had it, cause now the coolant looks like its coming out the belt.
Expert:  Neal replied 5 years ago.
A blown head gasket can be caused by overheating. You did not mention the new leak before, If there is coolant leaking near the belt that is usually the water pump. You might be lucky and just need a new water pump. You will not know about the head gasket until this new leak is fixed.
