the shroud is off my truck,will this have any effect on the rad. or anything else on the motor? thanks.also does anybody know of any nice aftermarket shroud that will fit a 79' f100,302 2 w/d.? thanks.
i never had a shroud on any of my ford trucks until two weeks ago. when we did the Big Ed swap i had found a correct shroud and decided to put it on. boy was i amazed. i have never experienced any kind of overheating in any of my trucks and i have always used the big mid 70's monster radiators but with a 195 thermosatat my truck ran a little warmer than i liked at long stoplights. i put the shroud on and now i can't get the thing over 200 no matter how long it idles. we will see how it does during summer heat but it was 75-80 last week and the needle flat stayed put. i am actually very happy i bothered at all. hawkrod
Shrouds serve a purpose - that is why they are there in the first place. I learned that the hard way with a car once - cooked a tranny because there was not enough air flow.
Check your local wreckers for one or try your local auto parts store.

That is so true Eric.
Ford spends so much money on R&D that I worry sometimes when people go without thermostats in their engines.
I mean, Ford designs something with every factor involved, to work a certain way.
AFA Fan Shrouds are involved:
There is also so many heating concerns over so many Ford engines.
It has been proven over & over again that practically all ford engines need a fan shroud.
I know it sure changed the cooling ability when I put one on my Mustang.

The shroud keeps air that is forced out the back of the fan from curling around and entering the front of the fan increasing the efficiency tremendously. The continuous shroud up to the radiator core itself contains the air more and allows the fan to draw thru the entire radiator. Many aftermarket shrouds are just a ring around the fan which helps but they do not draw air thru the entire core like most (not all) OEM setups do.
One other radiator tip. When you mount an oil cooler or AC condenser try to center it over the front of the radiator. If you don't there will be an imbalance of pressure on the fan blades as they travel from one side to the other. This imbalance causes the fan to flex under load differently and you get increased fan noise from the "flutter".

Hey, had a overheating problem. Read all the threads. Decided to go with a brand new rad. cost about $275 I think. And I bought a brand new Ford shroud cost $100 bucks from a local dealer. Already had a flex fan. In the Texas summer couldn't get her over 200 degrees with a 185 stat. Good luck with it all.
