Scottie-GNZ Posted March 28, 2005 Share Posted March 28, 2005 None of the answers I need will be found by a search so please do not slam me :D I currently have a 2-spd Escort fan with motor/blades that looks similar to the Taurus but does not move enough air on a hot day stuck in traffic. Currently I have the hi-spd turned on by the ECM @ 176 and the Lo-spd wired through a relay with a manual switch so I can run the fan with the engine off in the pits. IOW, Lo-spd is never used unless I turn it on and cooling is by the Hi-spd only. While the engine is out, I plan to upgrade from a 22x19 aluminum rad with the 2-spd Escort fan to a 24x19 with the Taurus fan. I know the fan will need to be trimmed. My question is, can I wire and run the Taurus fan as I do today? I realize I will need 10-gauge wiring and a 40-amp relay but my concern is running the Taurus fan on Hi-spd only. If it helps in the consideration, the GN alternator is a 120-amp and I can get a kit to upgrade it to 200-amp. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 28, 2005 Share Posted March 28, 2005 I don't know if this will help you particular situation, but it was a good thread on wiring these fans to use both speeds. http://forums.hybridz.org/showthread.php?t=99700&highlight=Fan+wiring HTH....

Scottie-GNZ Posted March 28, 2005 Author Share Posted March 28, 2005 The top diagram is how I have my fan wired except that thge trigger for the Lo-spd is through my manual switch and the trigger for the Hi-spd is from the ECM. I just want to know if anyone sees a problem with the running the Taurus fan in Hi-spd only considering the amperage. Quote Link to comment Share on other sites More sharing options...
jeromio Posted March 28, 2005 Share Posted March 28, 2005 Mine is wired such that both speeds are controlled by the ECM. I've only seen the high speed come on once. That was during intial shakedown when I was turning it on manually. My ECM is programmed for the low speed to come on at 186 and high speed - I dunno, I forgot to ask. It only ever comes on low speed and only when I'm sitting still and then only for a few minutes. The fan isn't supposed to draw more than 40amps, right? I hope not, b/c that's the rating for the fuse and relay I used. It moves a lot of air on high speed. I doubt it will be on for very long - depending on how hot your motor runs. Especially with a larger radiator. I think it would be fine - kind of overkill though. I'm surprised your ECM doesn't have a program that supports a 2 speed fan. If it does, I would use it.

spotfitz Posted March 28, 2005 Share Posted March 28, 2005 I had mine wired for high speed only as a pusher(still an inliner) for about 6 months and didn't have any problem. I ran 10 gauge wire and a 40 amp relay triggered by a sensor in the thermo housing, like the first pic in the post posted. It did run for very long due to the air it moves. It makes it easy to sweep the garage floor without lifting a broom too. Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted March 28, 2005 Share Posted March 28, 2005 Scottie, I run mine on High only, with no problems. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted March 28, 2005 Author Share Posted March 28, 2005 Thanks all. Looks like I will wire it up as planned. Jeromio, the ECM does control 2 speeds but I believe the Hi-spd is triggered for A/C on and some ridiculous temp like 210-215*. Never want to see my temp get that high before corrective action is taken. BTW, anyone have a 24x19 Griffin for sale that is not all beato to sh*t? Looking to sell my 22x19 with a 2-spd fan.
