Loud engine fan. Help needed

[A_HuL]

Hey guys I did a search but couldn't really find what I was looking for. My engine fan or something by it seems to be running a lot louder ever since I got back from an offload trip. Has anyone else had this problem or knows what it could be? Maybe sand or dirt somewhere? Loose belt? Any help is appreciated
Thanks

What exactly do you mean by louder? Does it sound almost like the truck is about to take off? (Jet engine/turbo fan like sound?) Does this noise go away or stay with you from start-up even after the vehicle has warmed up?

Most likely the fan clutch has given up on you.

Yeah it sounds more like a truck and it does it the whole time warmed up or not. Is there a way to tell if its the fan clutch?

I would say easiest way to tell is to turn the fan when its cold, it should turn fairly easily and not have any resistance to it.

Please do this with the engine OFF...

When you did a off road trip where you in soupy mud, water under carage hieght water?

Some of this info could help give you a direction to look at.

Yeah I mean there was a lot of mud and water holes so It got pretty muddy underneath, also framed it out the other weekend and my fan was chopping water so this is why the only thing I can think of is mud or sand or something

Possable fan clutch area, but, not with mine when I did the same off roading.

In the same area, you have pullys for your serpinten belt and a tensioner with a pully on it. Good possability on any of them as they have bearings in them. You can use a stethascope for mechenics that have a metal rod on it or a long screw driver. Will motor is running, you touch the mounting brackets that these items listed above are attach to and you can here if there is grinding sounds in there. BE CAREFULL NOT TO TOUCH MOVING PARTS WHILE DOING THIS, I'M NOT RESPONSABLE FOR F/U.

These pullys are what I got a lot of water and sand into and what was making all them noises, my starter went next as the sand got into the armature. Andof course in between the brake pads and rotors and needed turned when pads needed replaced.

Good luck on finding and be carefull as you can usually find where the sounds coming from while motor is running only.

Yeah I'm gonna give my engine well a good wash and see if that does anything (around the fan) then if all fails just take it to the shop idk, thanks for the help though its a good start

I would suspect the fan clutch first, or maybe a bend fan blade or two.

Is a fan clutch expensive and hard to replace?
