Hood Latch, not working properly... Options

[BonzaiCelica]

I got my car painted a while ago, the opening of my front bumper was not covered up so everything was painted red. i took off the front bumper took off radiator support and in order to get to that support i had to take out the hood latch (i painted everything black). when i put my bumper back on, i tried closing the hood like i normally do and it doesnt close with ease. you have to really push it down hard. whenever i prop open the latch from the inside, the hood does open right away. i have to physically open the hood, and then press the latch to open the hood.

also we dont have two radiators in our car right. what is that thing in front of the radiator that looks exactly like a radiator and the water pump is connected to it???
