GMC Envoy Sounds Like a Diesel Truck

reverley

I own a 2006 Envoy 4x4, auto. When starting from a stop (in auto select drive) it sounds like a big diesel truck but the transmission is shifting fine. Could this loud "blower" sound be the fan clutch? Once driving the noise goes away until I stop and start again.
Much thanks,
Ray

My 02 Envoy does that at times, sounds like the fan clutch. Bill

My 2004 as well, and then started to over heat if I had the A/C running. Clutch fan replacement fixed all.

my 2003 envoy had that same problem last summer. was the fan clutch. dealer wanted $7-800 to replace. clutch comes with fan as one unit. runs $3-400 for the part alone. mechanic charged me $580 to do the job. have to drop the radiator and rent a special tool to remove the fan from the main drive yourself ($60 bucks or so.)

This occasionally happens when I start my 02 Envoy in the garage for the first start of the day. It's real loud. After I go a few blocks, it usually calms down to normal. I assume it is the fan clutch thing, too. I haven't been eager or excited about fixing it, since it's intermittent, and goes away fairly quickly after I drive a little bit. Is it mainly just a nuisance that is not causing any damage/problem? i.e., is there any technical reason to fix it, if I can live it with on odd occasions and it goes away?

I have a 2006 Envoy Denali with 86000 miles on it. I've noticed when driving for long distances it will start to sound like a diesel. This seems to correspond when it is low on oil, which GM can not explain. It sometimes uses 2 quarts of oil between the 3000 mile change.
