[email protected] Posted July 16, 2021 Report Share Posted July 16, 2021 Hey guys I have recently had to replace my clutch fan and I've been through two different ones. First one sounded like a bulldozer (never unlocked) and the second one is almost as bad as the first. At the parts store there is no specific "silverado ss" on the data base. Is there a different fan clutch for the ss? This is very annoying. 2003 silverado ss. Thanks Quote Link to comment Share on other sites More sharing options...
dcairns Posted July 16, 2021 Report Share Posted July 16, 2021 I had mine go bad around 10 years ago. I had just had the AC compressor replaced at the dealer. And the fan clutch apparently failed and took out the AC compressor by not working correctly. Somehow the engine stayed cool enough not to seem to be a problem. But the dealer fixed the compressor under warranty and for some extra, replaced the clutch. I assume it is as close to the original GM part as possible. So far it is still working good. You might look at what the local Chevy dealer sells over the counter. Sometimes it pays to pay for the GM part, sometimes you just pay too much for things Quote Link to comment Share on other sites More sharing options...
someotherguy Posted July 17, 2021 Report Share Posted July 17, 2021 For a 2003 6.0 there appear to be two different GM fan clutches offered; one is for a non-A/C truck (15911779), other is for A/C-equipped (20913877) What brand and part # fan clutches did you try already? If they're other-than-GM they might be an even more universal application and less likely to behave same as original. In the aftermarket lists I sure see a lot of "SEVERE DUTY" listings which makes me think it's gonna sound like a city bus. Richard Quote Link to comment Share on other sites More sharing options...
dcairns Posted July 19, 2021 Report Share Posted July 19, 2021 Yes, those super heavy duty clutches are really noisy. Went through that trying to cool my 64 Impala. You may as well bolt the fan to the pulley. Quote Link to comment Share on other sites More sharing options...
