2004 Infiniti G35 Coupe Auto Trans, I’m running the 350Z Mishimoto fan shroud, the connectors are the same as the old OEM fan shroud so it’s plug and play no wiring done at all. They come on when the car gets around 203 with no A/C and when the A/C is on the fans stay on the whole time which keeps the car cooler than with no A/C. I believe the fans are two 12 inch fans pushing 1100 CFM each according to Mishimoto’s website. So 2200 CFM for the fan shroud.VStar650CL wrote: ↑Mon Sep 26, 2022 3:16 pmWhich Mishis do you have? Mishimoto makes good stuff, they may just be undersized. And are you sure they're wired correctly? I can't get specific without knowing which exact model you have, Sedan/Coupe and A/T or M/T. The fan setup is different depending what you have. However, they all use 2-speed fans with multiple relays, so if the wiring isn't mated correctly, it's possible your Mishis are working but not kicking on the right speeds.
Thanks for the info and I’ll try to give your idea a shot, do you know how I would go about wiring up something like that to switch the fan on earlier?VStar650CL wrote: ↑Mon Sep 26, 2022 5:04 pmI just checked the FSM and it looks like both the fan behavior and temps are both pretty normal. See EC-466 here:

Seems like Infiniti designed your ride to run a little bit toward the hot side, but I kind of wonder if that isn't an early design hangover from the bad old days of clutch fans. Either way, in those SoCal temps, if you want to kick the fan on low speed at an earlier temperature, it's easy to do with a temperature switch and a box relay parallel to the low speed relay in the IPDM:
