Why does the factory fan on the 77's blow towards the radiator instead of towards the engine?
I just looked at the stock clutch fan from my 72. The blades can be mounted wrong.pws69 said:Not possible.
Sounds like someone used a fan made for a SERPENTINE belt system.
When you use a serpentine belt system, you MUST use a REVERSE ROTATION water pump.AlwaysWave said:I just looked at the stock clutch fan from my 72. The blades can be mounted wrong.
Doesn't a serpentine belt system still turn the blades in the same rotation? If not, then the water pump would turn backwards.
Actually, I believe you are incorrect about the fan, but I don't fee llike debating.Jlreyna said:Let's not get confused here.
Stock fan from a 1977 corvette base engine with a/c and power steering. No serpentine and the water pump is flowing correctly. If you mount the fan backwards it will flow towards the engine, if you mount it normally it will flow very well towards the radiator. If you use a cowl induction hood, block off the front grills, and do away with the air dam it will make a good cooling system, with reduced heat in the engine compartment and colder air to the breather.
Anyways I have dual 12" electric fans on there at the moment.
