Re: What did you do TO your FJ Cruiser TODAY?
This is really neat! I've been wanting to clean up the engine bay. I used a dual Fan controller before but along the lines that it only turned on 100% based on the desired temp, so I would have one wired to come on at 170 and one at 190+. Usually if I'm not in a rush, there's no issues with spikes but if I was running hot and stalled, the fans would be on while trying to crank. I like what you're telling me though. I just realized several other companies have a PWM similar to what you were mentioning. Are you using a particular brand that you can recommend? It's been a long time since I've looked up e-fan technology and a lot has changed in controllers.
This will definitely be added to the list..
if and when you do, several companies make the controller. You would install the fans and tap radiator hose for coolant/engine temp. Then wire the control box for fans and one for A/C relay(? I haven't done this but assuming from DocME's post). I think it's more difficult than it sounds.. but getting a proper shrouded fan to the radiator like Doc's setup is the most important in how it'll pull the air.
