So I have a kit I bought awhile back including radiator, fan shroud, dual fans, temperature sensor, & wiring. I'm curious to if ill need anything more to make them work with my A/C. My kit only came with one relay & I was told earlier this week that dual fan setups are meant to be used 1 fan for cooling, & the other for the A/C...

 

I'm a newbie at such things.

i have the flex-a-lite set up , it has a controller,  everything wires into that controller will regulate fans for cooling engine and a/c, my advice before you do this is upgrade your battery cables all power and grounds, they talk about doing the big three , batt positive to alternator, ground from alt to batt , starter cable to batt , and engine ground to frame or body. you can look those up on youtube , but i have a 23 yr old truck , so i upgraded all cables to 1/0 heavy duty, that way there will be no power drop anywhere , also make sure you use 12 gauge wire for your power source , there is a guy on youtube that did it all the wrong way and almost burned up his wiring harness, and while in thinking about it you might want to upgrade your alternator to a 140 amp, the fans will pull alot of amps. thats why all the upgrades to run the fans and save your wiring harness.

if you dont have the flex-a-lite setup ,  painless wiring has a relay set up just for electric fans, i think it has 4 relays all wired ready to go.

Thank you for the reply & all the info! I really appreciate it. Does this look about right to you, friend? 20210529_110934.thumb.jpg.a8a22101a42dc0991e74bee6e8d32848.jpg20210529_110956.thumb.jpg.31f34931c3ad505ee78e72196ed08127.jpg

      OCI, not when but why?

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
