engine cooling fan

[hummerh2ksa]

Hi all

I?m from Saudi Arabia and have a 2004 H2. I have a problem which I believe is common with all H2?s. My problem is simply with the engine cooling fan. It makes the engine very noisy when it kicks in. I understand that the cooling fan is programmed at certain temperature and will work for short period of time just to cool the engine below the setting temperature and then engine sound and power is back to normal. My problem with that is when the cooling fan kicks in while I?m climbing a soft sand dune (when the engine full power is needed). The engine would sound very noisy and scary too.

Is their any engine upgrade that would keep the engine cooler and maybe add more power to the engine? Any ideas?

Thanks,
