Re: Fan Type?
Flex fans are a bad idea, fins can fly off at normal highway speeds, the plade wil slice right through the sheet metal, and if your head is there (tuning and reving) it'll cut through it just as fast.
GM used to use flex fans, but there was a huge recall on itfor these same reasons.
If your eng temp dropped after putting on a flex fan, then your fan clutch was out to lunch. As far as engine driven fans go, a thermostaticly controlled clutch will conserve more power, and control the temp better than a flex, a fixed fan, or a non thermostaticly controlled unit.
