 Subject: need advice regarding cooling fan clutch
IP: Logged
Message:
I have a 99 v6 dak 4x4 3.9L with about 68k miles. Three weeks ago I brought it in to check out a front engine noise that I thought was the belt tensioner. It turned out it was a worn fan clutch and water pump. So the garage replace those two parts. Since then when I first start the truck and drive it the fan makes this really loud noise almost like a flex fan would make. It does this for a 1/4 mile or so then goes away and the truck sound normal. I've noticed that the fan sometimes also does this noise while driving...it'll come on for about 15 secs then go back to normal. I took it back to the garage, they checked it out and said the fan cluch works on hydraulics and that it was working fine...I should expect it to do that. Why would it do that when the old part had never done that since I bought the truck new in 1999? Does this sound right?
Thanks for any help or advice on what I should do next.

My fan clutch does the same thing, but really only when it is cold outside. Never in the summer.

that sounds like normal clutch fan operation. if you don't like the noise, you can eliminate the clutch fan with an electric.

Daddio...that's what the technician told me. But my question was...why, in the 9 years I've had the truck, why haven't I heard the fan clutch make that noise before? He told me the original part probably never worked correctly. Does this make sense?

pretty easy answer & you answered some of it yourself
"9 years" parts wear out bud

could be the original part never worked properly. when i had the clutch fan on my '00 it would sound exactly as you described. when i'd start it up in the morning, summer or winter, it roar for about 1/2 a block then quit. in the summer in stop & go traffic with the a/c you could hear it every now and then as it needed.
since my truck came from the factory(as all did from '00- up) with an electric aux fan, i removed that pesky clutch and fan and run with just the electric. no problems or loss in cooling performance at all.
