ya i replaced it with the thin one and put everything back to stock with a new fan clutch and shroud and it still wanted to overheat so i went with the larger one with no shroud but i need the ac on when it his over 100 and overheating a new engine is no good...lol

 

as far as a fan controller, you can get a kit at autozone for cheap that comes with a thermostat and relay setup. this kit will mount a thermostat in the radiator fins and the fans will come on at whatever temp you desire.

I wired my fans up to a relay and a switch under my steering wheel that only has power with the key on. i can leave my fans on always, or switch them on when the temp gets to half. i like the switch better.

also, you got two (2) red fans right? you will need two to get the proper cfm.

 

ya i ordered (2) red fans to do the setup you did....ill let ya know how it goes...they should be here monday or tuesday the company isnt far from me...

 

ok cool man good luck. the wiring is pretty straight forward. i put the relay near the batter mounted to the radiator support. let me know if you have questions. the fan kits should come with the mounting pins

 

so.....i ordered the fans from a diff ebay seller cause that seller was just a jacka$$....same fans though with a warranty they should be here thursday

 

Do you have an aftermarket temp gauge? Or are you basing your overheating by the factory gauge? Because the factory gauges are not very accurate. I would run a aftermarket 3 gauge pod to better monitor your fresh engine. $50-60 at a local parts store. Also, what temp rating is your t-stat? Could try swapping to a 180 degree one. Also what is the condition of your radiator, coolant, and water pump, and fan clutch?
I am running a stock water pump, fan and fan clutch, Factory HD rad, and a 180 degree t-stat in my Bronco with a 440+ hp 358W. And sitting in bumper to bumper traffic in 95 degrees, it never got over 200. And cruising down the road it sits right at 175-180. I'd check your entire cooling system before spending money where it may not be needed.

 

entire cooling system is new. has new engine, new radiator....there isnt a thing on this truck that isnt new...lol just i have no shroud and it wants to over heat when it hits high temps outside

 

well did the install today and now it's worse...i can feel more power with factory fan off but the dual fan set up isn't good. wtf else is there for cooling options on this damn truck!!! oh and i have autometer gauges in there also factory is gone

 

I went back over this thread but did not see you answer TheGageinator's post about the 2 most important things to note when doing this upgrade.

Since it seems like you have them installed correctly and all parts are new in the cooling system the only thing to do now is triple check the fine print. Pictures might also help as more then 2 eyes looking at a project are sometimes better then just 2...

 

cant figure out how to post pics...it was only 86 today and with the ac off it was at 210...with the clutch fan it would have been at 175-180 with ac on damn electronics...lol
