Electric fans;

MARK VIII electric fans
Taurus SHO fans
I think the MAxima fans are a direct fit for NA radiators

I have ran shroudless in AZ, not in the middle of the summer mind you, had no issues on NA or TT. NA was stock and TT had Aluminum 2 row and stock NA fan clutch. I never had any cooling issues at all. Even when I drove it from AZ to CO.

Well when i do my upgrade, i plan on getting a light weight crankpulley, nismo thermo, newer oem rad for weight reasons, but i was on concept z and saw that they tyc depo fans that show they fit up to the stock rad. anyone ever add these on with good results?? also noticed the other day that the fan in front of my ac condencer was seized up (explains why my ac doesnt work now) can that be replaced without removing the bumper? also any advise on which products to get as far as fans go? id like to very much be able to drive this across country and back, while maintaining great temps, ultimate reliablility (for the car in general)

1989-1994 maxima fan is what Ive seen offered on concept z

both fans have 2 speeds, so you may want to consider what type of fan control you will be using. N/A models only have single speed control.

I do not know for sure so i cant comment. i have debated doing the fan upgrade but it keeps getting bumped off my list.

Ive heard the 89-94 will bolt up to a NA radiator just fine, and i dont think coz would sell something that doesn't fit right either.

Hopefully someone else can chime in.

The 96 fan will not fit. The bottom does not mount the same way as 89-94

Just an FYI regarding the AC recharge, you will have the old style refrigerant that cannot be recharged, so you will have to upgrade to new refrigerant which also requires some work, and a lot more $ than a simple recharge. For this reason I left mine uncharged after my accident- not worth a lot of money for a day or two of AC per year.

I have a good hook up for it. But here on the east side of Washington it's around 85-105 all of the summer months
