Hey everyone. Gotta love this site! Helped with some pretty nice mods I've done.

Now I'm seeking help with a mod myself. My 2000 Civic DX Hatchback doesn't have AC but I want to get the AC fan and mounting brackets and connect it up to aid in cooling the engine bay.

How would I connect this fan so that I wouldn't need to use a switch in the cab? Would I just tap it off the line coming from the radiator so that it'd turn on and off when the rad fan turns on/off? If I do that, would it pop fuses?

Thanks in advance!

 

Are you talking about the blower motor inside the car or the condenser fan?

edit: you can wire it in series with the radiator fan or do as you say and wire it to a relay and switch.

 

This is an interesting idea, here's a few things that popped into my head:

1. Why do you want to add an extra fan? The stock cooling system should be more than sufficient to keep engine temperatures in check but maybe you're running a turbo/other mods that necessitate increased cooling? Or ambient air temperatures are always extremely warm where you live?

2. You could upgrade to an Integra radiator and dual fan setup, but I am not sure if this is possible for 96-00 models.

3. I'm not sure the A/C fan will mount without the actual A/C condenser itself. I think the A/C fan is attached to the condenser which is held in by brackets. You might be able to modify something to get just the fan and shroud to fit but it might not be ideal.

4. To figure out whether or not you'd blow a fuse if you linked it up to the radiator fan, you'll need to figure out how many amps that the A/C fan draws. Then you'll also need to figure out the amp draw from the radiator fan. Then, determine what else is on the radiator fan circuit (if anything) to get the total draw and make sure it's lower than the fuse rating on the radiator fan circuit.

EDIT: See Tony's post above, looks like you can wire it in with the radiator fan.

 

It'd be the condenser fan. I'll have a look at the wiring and check to see what the amps are for both.

Thanks for the help :D

 

I'd like to have the extra cooling as it gets pretty hot here in the summer and sitting in traffic isn't the best feeling. I don't have AC in this car and have swapped to a 4-2-1 header and the bay does heat up a bit more then normal.

Having that fan in front would help cool it down. I'll be wrapping the header soon to keep the heat in but would like the added cooling for sure.

I've swapped by D16Y7 intake manifold for the D16Y8 and with a CAI it pushes a bit harder and seems to heat up faster, but with a new 3 chamber radiator, it's kept the thermostat looking good.

I'll check the amp loads on both fans and see what I can mod up to make it fit. I'll take pictures if I'm successful at this.

Cheers
