There are two comnpletely different issues being raised in this thread. They cannot be compared with each other. A lot of clutch fans employ a viscous coupling. This means that at idle they are not using any power, whist they do spin it is very easy to stop. You can start the engine and hold the fan to stop it from spinning, as you rev the engine the fan will become harder to hold. Most thermo fans are temperature controlled. This is the reason that people with EA- ED series falcs put them on from the EL - EF falc. They only switch on when a temperature limit is exceeded. This means if your going 80KM/hr or above it is likely that your thermo fans won't be on at all because the cooling provided by the air moving through the radiator is sufficient to keep it cool. This does give a power saving because you are not powering a fan needlessly. This is one reason to use a thermo fan, another is space they are usually slimmer and take up less room than a clutch fan. Note there are other designs for fans such as hydralic control which can also be employed to power a fan. Andres, the alt is driven by a belt so it adds the losses that would be taken away from not driving the water pump. Plus alts aren't 100% efficient and do have a lot of slippage at high power. Also there is no such thing as an indepentant test. I do research for a living and there is no such thing. We all get our funds from somewhere and its a very competitive world. Also a a side note - standard brand new water pumps are not very well made. They usually have quite large gaps between the impeller blades and the housing which lowers flow and efficiency. If you have a high power engine then having a new housing made which fits the impellers better will substantially increase your water flow. I have done this for friends cars but I don't know if it would be commercially viable to do given the work involved. Also a lot of cars have bad water pumps. I had a datsun once which had no blades on the impellor but the engine still didn't overheat. They are an area which recieve no maintenace or regular checks. [Report message to a moderator]
