HOrnbrod Posted September 30, 2015 Share Posted September 30, 2015 Will the new electric fan be your primary fan? Mine is, and I have a 2-speed controller. I ended up with the LO speed to come on a 190*, and the HI speed at 215* after playing with it looking for the ideal settings. Been working well like this for years. If you have a 1-speed controller, I'd set it at ~190* to start and see how it does. You will have to play with it........ Link to comment Share on other sites More sharing options...
big66440 Posted September 30, 2015 Author Share Posted September 30, 2015 Yes it will be the primary fan, do you have any recomendations on good controllers? I remember from another thread you had/have a Spal controller would you guys know of a reputable company for one? Link to comment Share on other sites More sharing options...
kazam Posted September 30, 2015 Share Posted September 30, 2015 My Opinion: Those Peviously Stated Numbers Sound Correct: IF YOU BOTH Have the Same Engine. Type of Engine & Specifics are important; "hotter" within temp. (for your engine) may be Much more efficient; Specifics may help for a better answer, provided.

HOrnbrod Posted September 30, 2015 Share Posted September 30, 2015 My Opinion: Those Peviously Stated Numbers Sound Correct: IF YOU BOTH Have the Same Engine. No sheite. That's why I said you will have to play with it. That's understood. OP, I'm still running the original Spal PWM V1 dual fan controller but it's NLA. I do have a spare in case it goes belly-up, but it's still doing it's job as it's supposed to do. You might want to search Ebay for a NOS one. http://www.a1electric.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=AEOS&Product_Code=FAN-PWM-V3 Link to comment Share on other sites More sharing options...

zomeizter Posted October 1, 2015 Share Posted October 1, 2015 I'm about to do away with the Flex fan on my truck, but I'm doing the "el cheapo" version: Volvo two-speed relay, T-bird two-speed fan assembly and 212 degree fan swicth. Have this setup on my K5 and works extremely well. Link to comment Share on other sites More sharing options...

Sure, the fan assembly is off a 95ish T-bird/Cougar with either v6 or v8 motor, the Volvo relay I got from a mid 90s sedan like the 740 series, and the fan switch is a Sorensen xx555, I can get ya more accurate info and pix later on...
