Here is a quick and easy fix for a F-body equiped with A/C that tends to overheat. I had to replace my radiator a while back after I broke it, don't ask. I found something that quite frankly supprised me. In between the radiator and the A/C condensor (the radiator looking thing in front of your actual radiator that all of your ac lines go to) is a small gap that had almost completely filled up with leaves and other misc yard debris. These leaves where obviously impeading the air flow through my radiator and hindering its cooling ability. Considering the sheltered life my car has had, I can imagine that some other cars could have this even worse than mine did. I highly suggest that every one checks this area on their car. It should only take about 15 mins., you don't need to take the radiator out to do this, just take off the upper shroud and pull the two apart just enough to get in there with something. This might not completely restore your cars cooling ability, there are many other things that could be hindering it, but it sure is worth doing.

Good Luck

 

mine had the same thing, leaves in between the radiator and condensor. well i discovered this when i flushed my radiator. a good tip nonetheless.

 

couple of months earlier I was crusing in the city and I was really suprosed when I saw temp little above 220 ,
I am checking temp gauge really offten because I`ve got bboht fans on manual switches, and I know exacly my car to tell when it shou;d be hot or not. I thought maybe smths wrogn with the fans got a little speed with no chenge.

stopped the car and qess what ha

bettween the ac radiator and a engine radiator there was a thins plastic bag

I dont know how this suck up but it was blocking air really good
