Fan Delete for the Winter!



One of my fan blades broke during the summer, so I decided to wait and do a fan delete just for the approaching cold weather. There is a mildly noticeable improvement in power, probably on par with the catback (which, BTW, is the least effective power mod I did), but without the soundeffects. So for those wanting to do a long-term fan delete mod, now's the perfect time to try it out at zero cost before springing for the hardware when the warm weather approaches. Personally, I'm sticking with my fan for the summer months, but I think I'll do the fan delete every winter.

Unless you're changing the thermostat, adding water wetter, and all the other steps in the actual fan delete mod...you will have issues with overheating this winter. If you get stuck in traffic, it WILL overheat.

lol Jay, shhh don't ruin his fun.

P.S. I'm doing the same thing but have added water wetter and am awaiting the kit from understeer. No overheating issues yet but I don't let the car idle and try to drive at night only. My fricken aux fan is broken :@

-Take out your t-stat and cut the spring out for constant flow
-Remove the AUX fan completely as it just restricts air flow when not in use.
-Add water wetter
-Remove clutch fan..

= No overheating ever.. even in Florida temps and traffic jams.. You may not get the heat you want during the winter here tho

Well, for the 3 days I've driven it so far, it seems to work pretty good with no temperature readings beyond the mid point on the gauge, but then, the stock gauge is probably not the most accurate. Maybe I'll try a combination of some of the suggested ideas:
- remove the aux fan
- water wetter (I've had some sitting around for some time now)
- lower temperature switch

This way, the fan delete mod is a lot easier to switch back and forth between summer/winter. The tstat is too much of a PITA to remove (even after doing it 3 times over the years). Besides, I don't like the idea of using a lower temp tstat in cooler weather anyway.

I kind of like the smoother and quieter idle with the fan delete. I guess my broken fan blade had a lot to do with the vibrations I was getting thru the steering wheel

Actually, the lower temp switch will have no impact if I have no cooling fans, so scrap that off the list . BTW, what does the temp switch drive? The aux fan or the clutch fan?

The temp switch must be for the aux fan. So it's probably a better idea to leave the aux fan in place and use a lower temp switch. That way, if things start to heat up, the aux fan will kick in and provide some cooling.

Yes. Good job at answering your own questions lol.

Without the AUX fan (or a spal or something) your car will overheat in about 10 min of idling. You NEED a fan to move air when sitting still. Once you're moving, it's no problem, but obviously in a street car, you will be not moving a fair bit

LOL.... Yea i sacrificed the heat when I first came back from FL almost 2 years ago.. Kinda sucked.. but i was too lazy to change the t stat and hook up a fan.. Never did overheat tho.. actually while sitting at idle in the winter it would make it to the half mark but never further.. even after 30 mins + of idling..
