Auxillary fan installed in front

**StockEngine** · October 15th, 2017 02:45 AM

Not sure if this is ok. Normally fans are behind the radiator/condenser. Any comments or thoughts on this setup?

meron mesh in between? I think factory setup is behind kasi in case the fan blade cracks.. the shards will not damage the radiator.

nice and clean. i like it.
also, because of the large space around it, it will allow the use of cheaper, non-branded fans.

I remember '90s cars had fans in front... Another behind the radiator...

Fan in front is connected to the A/C compressor...
Radiator fan is linked with the thermostat...

I think '90s Sentras have 2 big fans behind the radiator... Instead of the front and back set-up...

many rear-drive cars of 90s and older, had fans behind the radiator. but to some owners, the aircons and engines got hotter in heavy traffic.
they added auxiliary electric fans in front of the radiator. the set-up resulted in cooler aircon and engine, and did not result in engine overheat when off.
i had one, myself.

my '97 sentra had two aux fans in front. and they gave me a big headache.
for a long time, i could not find the source of my engine's tendency to overheat in traffic. until an oldtimer mechanic showed me just how weak my old fans' airflow was, compared to the new ones'. we had to do it side by side, as my old fans still managed to push out considerable oomph.
strangely, the aircon was still acceptably cold. but it did get factory-arctic-cold, after replacement of the old aux fans.

Yes, it's a common remedy especially for "non-tropical designed" cars.

The aux fan infront of the engine typically draws air towards the engine, and the 2nd aux fan behind the bumper must draw air towards the engine as well... Ergo, one air flow direction towards the engine.
