After the H3 has been sitting a while (more than a few hours), does your engine sound noisy (like a roar from a fan) when you first start it and drive the first 100 feet.

You might have the same condition that I had where some coolant had accidentally dripped onto the fan belt. Take a look at it to see if you can see any fraying that might be caused by a bent or misaligned pulley too.
Take to your dealer and ask them to check out TBS for noises in your engine. After my belt was changed she was back to her old self.</span>

wannabeH3,
It's a beefy sound. It sounds like you're revving the engine faster than you really are. What is happening to make this sound?

Is it the fan clutch engaging fully for a short while causing the fan to go in synch with the engine (when it normally will be running at some slip speed). I know other GM trucks do this too (Avalanche, etc.).

I love that sound! Sounds like you're going to take off or something.

When you're moving while it's making this sound the engine RPMs stay the same as you hear the roar and then the roar fades away (while the RPMs haven't changed).
