has anyone done the manual radiator fan mod on a 2000-2001? i have looked at both the 4th gen and the 5.5 gen version. but i cant find the Pin number to use from the ECU?

are the 2000-2001 ECUs the same as the 4th gen? totally different ? or the same as the 5.5 gen?

 

I too would like to know this. I live in florida and summer is on its way (its summer 100% in FL) and when I go to the races, this would be a functional benifical mod.

 

it seems like no-body knows.. im gonna go look outside right now..

 

Not sure why anyone would want to do this to a Maxima. It would be more beneficial to remove the drive belt from your A/C compressor and use a shortened belt, and then just turn the a/c switch on, which forces the radiator fan to run. Haven't tried that, though.

If it's like most other cars you need to run a wire between the two outer posts of the rad. fan relay with a SPST (NO or normally open) toggle switch in the middle? or just find the +12v power lead going to the fan motor and wire it direct to battery + terminal.

 

well first off.. i know for a fact that your wrong.. the rad fan always has a power supply. it is simply switched on by a relay. which supplies a ground.. therefor compleating the circuit.

can someone tell me where the ecm is located. cause that would help out a great deal

 

bhhhhuuuuummmmmppppp

 

what u can do on most cars is if u can find the sensor that kicks the fan on and just jump the wirest. I'll see if i can find it sometime, unless someone knows where it is. Its usualy a little sensor with two wires coming out of it that is connected somewhere to a radiator hose.

 

i dont know if that would work either.. simply because that would only send a tempeture signal back to the ecu.

If anyone has the hanyes manual for a 2000-2001 can you please tell me what color wire is used to connect the Radiator fan (high speed) to the ECU? ussually it has initials like LG / LG/R Y/W stuff like that.. and the high speed pin would have an H at the end of its initials rather than a L

 

I did it to my car, ill look up on what wires i tapped into the ECM cooling fan high is #34 (LG) and cooling fan low is #35 (BR/R)... make sure you have a DPDT switch or else it WILL NOT WORK... i use this only for track purposes, i dont know about everyday stuff ... i think the maximas cooling fans turn on fine the way they are!!

if you have anymore questions feel free to let me know!!

keep the info comming.. and pics of the correct wire comming

 

WE HAVE ACTION.. i finished the mod tonight.. have to say it pumps air.. HARD .. best part is the sound.. sounds like a supercharger under the hood. WOOT WOOT
