I recently put the A.C. components back under my hood and am concerned about airflow across the radiator and overheating issues. I currently have just the standard 24" radiator and fan than came stock on the non A.C. 302 cougars less the fan shroud. The shroud that is supposed to cover the fan didn't come with the car and I suspect left long ago.
I guess the main questin here is should I replace the shroud and see what happens?
Should I upgrade radiator and add shroud and see if that is enough?
Should I ditch the current fan driven off the water pump and go for a single large electric fan or duel electric fans? Would this be enough with the 24" radiator, or does it have to go?
I know there must be a bunch of you guys out there that have wrestled with this problem and would love to hear what you did and how succesful it went for you. Should I go with the electric fan(s), I have heard there are a couple of ways to hook them up. Through a toggle switch in the car and through a temperature sensor off the intake manifold. Again, I am a little green on this stuff so any and all help is very much appreciated!! The shop that did te fill of the system seemed to think that the new 134a coolant needs a lot of air across the condensor and did not feel that in the current configuration there would not be enugh in traffic, just on the highway. They did not like the shroud being missing or the fan off the water pump. These are guys that work on modern cars so sometimes there are differences on the older cars that they don't take into consideration but have me concerned, none the less.
Thanks for all help
