Hey my car seems to keep getting hot and idk why. My water pump is good I got a new thermostat and changed the coolant and its still getting hot. Do I need a bigger radiator? It is a v6 car that was swaped to a v8 and it still has the stock radiator.

 

Try cleaning the radiator in back of the A/C condensor and check if your fans turn on correctly.

 

you could also try pull the rad out and running some water through the fins, over time a lot of junk gets caught up in there and by washing it out, you will get better air flow through it. Have you considered upgrading the fans? is it burning coolant? are the v6 and v8 rads different?

 

V6 and V8 models used the same radiator. Could be the radiator is restricted. Other things to look at:
What water pump are you using? Make sure it's a reverse rotation if you have a factory style serpentine belt setup, or standard flow with a conventional belt setup.
What kind of radiator fan and shroud are you using. If you're missing the shroud, that's part or all of your problem right there.
When does it overheat? If on the highway, make sure your lower air dam isn't missing.

 

It's the stock fan and it only gets hot when highway driving at idle it cools down

 

here's some photos

 

I can't tell if the picture is blurry or if the radiator is just that bad.

 

Yeah not great pics it's dark out

 

Fan works fine

 

It's not burning coolant
