I was wondering how to tell if I need a new/ better radiator. The temp isnt going up but i am experiancing issues when it is hot out. What are signs of needing a better/new radiator?
Thanks

really nasty fluid, and you can look inside the radiator and see all the fins and whatnot clogged up and gunked up. if the car is heating up when its hot out on the highway its a radiator problem, but if it heats up in stop and go traffic its a tstat, fan clutch problem

Well it doesnt heat up is the thing...it jus sorta stumbles when its hot out and ive been driving for a while. Sometimes itll heat up at idle if the a/c is on.
