"Fan delete mod"

[clavinZERO]

I suspect both of the relays are the same for the high/low speed. I will check later though; the wires coming to the fan from the relay box are equal in gauge it seems. My new fan is only a 10 amp draw anyhow. I will definitely take another look today before I tear into it.

The relays are, but the wiring and fuses might not be. I think the low speed fuse is 8.5 amps, not a big deal to swap out for a 10a or 15a, but I'd rather use the high speed circuit rather than worry about burning up some wiring and overheating my car. :)

If the wires are the same gauge, which I am almost positive they are, I will then just up the fuse rating like you said. I'll post pics and stuff eventually.

Good info to know, so I am digging this old thread back up, sorry guys!

so if i understand this thread correctly, i can simply remove my mechanical fan, replace the thermostat and pour in some water wetter and my car will have sufficient cooling in hot traffic with the AC on?

i went ahead and bought an electric thermostat so i don't go through fuses like a bag of skittles.

i couldnt find the exact one i purchased but this is very similar. This one is from JEGS.

you guys should check it out... its a good upgrade.

no, you need the lower temp thermoswitch as well, or your fan won't turn on until 90-99c.

and you also need to verify that your aux fan actually works..

yeah sorry, by thermostat, i meant the switch for the aux fan.

yes my aux fan should work correctly, i just purchased a rust free one with a condensor since my fan was seized and the condensor leaked.

what i wanted to confirm was that hot summer traffic days with AC would be okay. i know most guys who delete the mechanical fan dont run AC anymore.

[nando]

you can bypass the low speed on the thermoswitch so it turns on the high speed when it reaches the 80c threshold (just change the wires on the connector so it grounds the high speed for both posts). the AC will still turn on the low speed unless it starts to get warmer, then the high speed would kick in. that would work.

Why are people hatin up on clutch fans???

Unless clearance is the issue, clutch fans are awesome. I've seen 500-600 2jz's and rb25's still running clutch fans w/ no problems. Why get rid of what the BMW engineers spent millions researching for??

Just my 2cents

weight and engine drag reduction?

because it makes working on the engine easier.

[guibo09]

do you keep the fan shroud?

[lifeiskaos]

no

Point taken. But the whole "less drag on engine" doesn't really apply to our motors.

because it makes working on the engine easier.
