Cooling Fan Push or Pull

[visualpoet]

i tested w a digital temp gauge,

the same fan as you see in the picture

in a pulling position it took 1.45 seconds to shut off (OEM FAN SWITCH)
in a pushing position it took 2.94 seconds to shut off
wo no condenser fan pushing again 2.80 seconds to shut of

OEM fan, OEM location took 1.20 seconds

maybe i tested it wrong, but thats what i base my results with

This has nothing to do with how much air the fan moves. It has everything to do with how well it cools, and if it's pulling cool air into the engine compartment through the radiator (the way it should) it's going to cool faster than it would cool if it was pushing hot air out through the radiator giving you a lengthened cool down time. The OEM fans probably are the type that spin the same way regardless of polarity.

ninja - The reason for two fans is one is a regular temp activated cooling fan, the other is a secondary fan for extra cooling when the AC is running. If you don't have AC, you could go with one larger fan. I don't know how much air you need to move to keep it cool in CFM, but generally any fans that cover the majority of the radiator are going to move sufficent air to keep it cool. Most cars only need the fans when stopped, driving forces plenty of air through to carry heat away.

I mounted my slim fan in front of the radiator and wired it to push the air through the radiator. I like how it gives the bay a cleaner, less cluttered appearance.

Ok got it. Just for future reference, looking at the engine compartment from the front of the car, which fan is the cooling fan and which one is the condenser fan?

Looking at the engine bay from the front of the car the one on your right is going to be for the condenser.
