thanks jmc that will help alot ..

 

well i have cleaned the iac ..i have checked the cats .. i have pulled the rad out and cleaned it again and the roar is still there im at a 100% total loss on this

 

Take off the serpentine belt and start it up. If it doesn't roar it is one of the accessories or the new fan clutch that is deffective. It happens.
BTW don't run the truck more than a minute with the belt off.

that was gonna be my next step... stay tuned..lol

 

I pulled the fan off and started the truck and the roar is gone !! why is this now what do i do ??????????? im at a loss

 

the fan is probably out of balance would be my geuse

 

When you removed the fan and the noise stopped then the fan was casuing the noise. The fan clutch is what is supposed to keep the fan from turning at excessive speeds. It is the problem. Replace it.

Ok first I just want to say I opened an account just to post this. Has anyone forgot about the power steering pump ???




That would only make sense

I doubt this one but also the clutch to the ac compressor.

Just a thought
