+1 for e fans, what kind of temp sensor are you using? I'm looking for a dual range to go with my mk8 dual speed fan and Volvo dual relay

Right now just the included controller for the flex-a-lite 280 fans. It is a single stage unit with a prewired sensor that affixes to the radiator fins.

slid on an ice patch and crashed into a boars head truck. fortunately the only loss was the lower valance and the plastic bumper strip

Hope the trucks contents were okay.
nothing but a bruised ego.
the real kicker is that i drove this truck with a cracked valance for like 6 years and last month i finally replaced it. 2 and a half weeks later this happened .... you cant make it up! :emotions122:

Nice, those are cool for the adjustable temps, I was thinking of getting one of these guys here but i'm not sure if the temp ranges would work for a 350 or 383 any thoughts? napaswitch.png
it's a 3 pin sensor that closes ground on pin one at 190 and opens again at 209, then closes 2 at 209 up to 226. I'd also wire in a manual override that's connected to the ac pump so that when it's on the fan is on setting 2.

The open/close temps seem backward but that is about right. Sounds like it will work just fine. Mine is set now where it turns fans on when the ECT readout on my Scangauge2 (PCM not actually controlling fans just yet) sees about 210°F or more and when they shut off it reads about 193°F. It has an a/c trigger as well as bypass on/off (unused at the moment) functions. Some diagnostic lights on the module as well. Only tweaked it once after initial install to perfect the temps. I expect it to have no issues with a 383 later. My setup is quite effective and can handle more then it currently does now. Eventually the PCM will control them at multiple speeds and the current controller will be used on an auxiliary fan installed elsewhere at a later time.
