my dakota ī05 is very loud , when i first start it up every morning it doesnīt make any sound and runs great, but when it reaches some temperature it starts sounding like itīs gonna take off, and losses a BIG amount of horsepower, and it stays like that even if a drive it for hours it just doesnīt go away, i know it should be the other way around, does anyone know what could possibly be happening

 

With the engine off, see if your fan has any wiggle to it.

Your clutch in the fan is probably toast.

 

Are you sure that it's the cooling fan clutch that's making the noise? I don't think a noisy fan should cause your engine to lose horse power.

 

im pretty sure is the fan thats making the noise īcause when it runs on cold it doesnīt make any sounds and runs good but after 10 min under the texas heat it starts and itīs there when i feel it everytime i get a green light, it didnīt have any wiggle or seem to have any, but i changed it anyway, when i replaced it i took the truck for a short ride without the fan and it works just fine, so i installed the new one, but it went back to the same problem once it took some temp, im starting to think is a factory related problem, how about en electric fan? what u guys think?

 

Cant go wrong with an e-fan conversion. Mine works flawlessly.

 

what size electric fan do u recommend, my job is 70% off road, i donīt wanna get stuck with an overheated truck in the middle of the desert

 

i,m thinking 16Ļ

 

I'm thinking of a word. It rhymes with search.

 

Personally, I'd go to a salvage yard and get a Ford Taurus 2 speed fan and hook it up with a couple of relays and thermal switches (not temperature sensors, you'll need 1 switch per speed). This fan can pull through a LOT of air, and uses quite a few amps, so as long as you use the right size relays and wire, you shouldn't have a problem. This is by far, the most cost-effective solution. There are also Mark VIII fans that are very similar to the Taurus fan, but some of them come as a single speed - I recommend the 2 speed in this variety as well. If you go with a more sophisticated controller at some time, you can always just use the high speed wiring and leave the low speed disconnected.

 

i just noticed that the mechanic installed a heavy duty fan clutch, do you think this may be the cause of the problem, any way, i dont wanna know anything about clutches anymore, iīll do just what u said and post back, thanks a lot
