PO526 my mechanic said was either the fan clutch or the harness going bad. Had no temp issues and fan seemed to be working fine. Replaced both fan clutch and harness. Now sounds like plane taking off at start up and first 4-5 miles of driving then seems to quiet down. If I stop and turn off truck and restart does it all over again. Mechanic said it will take a couple thousand miles to "break in" but then should be better. Is this true? Seems like people talking about that kind of noise is when it is going bad?? Has always been quiet for the past 2 years I have owned. Thanks for any help.

Now they ALL will do that with a 'clutched' radiator fan! This one is a bit different as it is an electrically controlled clutch (electro visco).. The drive fluid is ...well, viscous until the engines runs a bit... It should get better! ... You've just never heard it with a new, working fan clutch!!
That's what my mechanic said. Hydraulic etc. cold fluid etc. Just wanted another opinion. I should know better. Been going to him for 10 years and have never had an issue or problem with his service, Best I have ever had.....this is just SO loud that is was a bit shocking compared to what it has been for the past 2 years.
Yeah I know, it's best to stick with that one mechanic for ALL your auto repair needs!... He knows your vehicle better than anybody else! I see folks running from one place to another... Then nobody knows what's going on... Sounds like he's got you covered!!
Thanks!! Will update either way!!! Just amazed at the sound level. Can't here the radio first 10 minutes of driving it is so loud.
