6.0 Powerstroke - Mechanical Fan Clutch Performance

[@malonefamily4568]

Thanks for sharing my 05 6.0 runs a lot cooler I was in the low 230s before I did the fan clutch mod now I barely see past 210-215 on coolant & oil temps

[@grumpysdiy]

Check out my oil cooler back flush video, might help you decrease those temps some more. Thanks for watching!

[@Mrjjeffrey3375]

can you cruise 85mph towing or even 75mph with engine oil temp only 215?

[@grumpysdiy]

In my truck I can do 75 on even terrain towing our keystone premier yes I can stay under those temps. However I don’t know anything out what your towing or where or with what.

[@fatguyonagrom9515]

IMO the best upgrade I've done myself, no more puking and A/C Blowing Cold at Stop Lights. There is a huge misconception that make people think they need studs and 90% of them are from EGR Deletes not bringing on the Electric Fan, Thus Boiling Coolant out the Degas Bottle.

[@grumpysdiy]

I agree my temps never crept up again, even a long pull of a grade would only raise the temp to like 206 F.

[@dakotadale567]

Stumbled across your videos and where the 6.0 is concerned you are clear, concise, and straight to the point with no filler. The info you give is always spot on too (coming from a diesel tech that works on these for a living). Good job. I wish more guys put information out on these in a similar format or at least with the data you always provide.

[@grumpysdiy]

Appreciate it, I guess I’m doing well for having never been a mechanic.

[@NomadicInNature]

That's nice to have. Thanks for sharing.

[@grumpysdiy]

Thanks

[@Powerstroke431]

Why not just do the blue wire mod?

[@grumpysdiy]

Never heard of it, but I am assuming it is a power wire straight to the fan to turn it on when you want?

[@Powerstroke431]

@grumpysdiy Something like that yeah .

[@grumpysdiy]

I highly recommend a mechanical fan clutch for any truck towing!!

[@gabewalker7604]

What month was this? We always travel when it’s hottttt

[@grumpysdiy]

I don’t remember the month. Somewhere near the upload date. I remember in the end ish of the video I talk about how it is on the other side of that mountain.

[@gabewalker7604]

That’s cool. We have huge grades and hot temp up in the mountains here in California. Clear lake was my hardest…. 235 up there. I saw improvements with my A/C too after I installed mine

[@kristinesharen1754]

just did this conversion with a BPD water pump in my 2004 f350..Ive got the EDGE monitor with a 50 hp tow tune. I tow a 7000 pound dry 30 foot travel trailer. Im guessing when we are fully loaded we are somewhere around 9500 pounds with the kids and coolers. I generally camp in the Graeagle,Ca area towing from Reno,Nv. Not a long haul by any means but some steep grades going through N395 and hwy 70 to Portola, Ca. I was use to seeing easily 215-225 oil temps..even seen it as high as 235 heading up to Oregon dunes last summer. I noticed after the conversion, no oil temps higher then 207. We are going to the Tetons in a week, well see how she handles the grades then, overall though I'm very impressed with this easy conversion. My truck is mostly stock, intake, exhaust and the 50 hp tune that's it.

[@grumpysdiy]

That is awesome, I also did the oil cooler back flush to remove all the crap in the oil cooler when I did this mod. I have a video on that as well. kzbin.info/www/bejne/gGjSiIBvfcyKZs0

[@danielwhittle4317]

What oil cooler do you have

[@grumpysdiy]

Oem

[@antonioaa8097]

Great review. I looking to do the same upgraded. This weekend I towed in 110 to 115 degrees and oil temperature was in the 230 going up some grades.

[@grumpysdiy]

I recommend getting the oil cooler back flush piece and doing a back flush at the same time. Good luck and let me know how it works out!

[@John-rr7bf]

Thanks for the video! Question, is that 7.3 fan conversion extremely loud or annoying just driving lower speeds around town? I don't mind a loud fan climbing hills etc but don't really want an annoying fan sound with just normal driving. When you start up on a cold morning and start driving does the fan sound pretty loud? Or is it only when the engine temp is up working the truck pretty hard towing a trailer? Thanks!

[@grumpysdiy]

It is louder, but not a ton at city driving. I’m so use to it now though it doesn’t bother me. Also I used to have a 95 7.3 too so also used to the sound.

[@John-rr7bf]

@@grumpysdiy good info thanks again!

[@grumpysdiy]

Sorry it wasn’t more help.

[@John-rr7bf]

@@grumpysdiy It was a great help! I ordered the fan clutch and the adapter through your Amazon link. I figured if the noise annoys me it's only a $100 gamble lol I can always just go back to the OEM fan clutch if I want

[@grumpysdiy]

I can tell you this. I figure out I had a head gasket leak. Leaking exhaust gas into the coolant. On up hill pulls with my camper the temps went from a normal 200 EOT to 235. Then back down to 200 off hills. So that goes to show how well it worked getting me home from Utah to Texas.

[@AshlonHill]

I just bought a 6.0 do you use tow mode? I’m picking my truck tomorrow with the usual bulletproof upgrades.

[@grumpysdiy]

Yep I have a programmer on it, programmed to tow mode.

[@strato_5459]

for anything of significant load turn it on. it keeps the truck in the power band a little longer and helps big time with hill climbs and offers a little engine braking to help on the down hills. on my SCT x3 it has a few canned tunes, i use the "jake brake" setting and the aggressive tow haul and man it will keep 14,000 lbs in check with cruise on down hill no problem it is great. the settings are way better then stock but the stock setting is a must use as it just make everything feel better

[@grumpysdiy]

Well said.

[@parales03]

How did the oil temps get get to the 170s. What was the temp outside?

[@grumpysdiy]

Well with the mechanical fan clutch and exhaust brake when going down hill the truck cools off pretty fast.

[@parales03]

@@grumpysdiy Awesome!!!!!!! I’m getting mine installed today, I had the same issues my oil temps were at 230ish and that’s with no tow going 60mph Weather was at 105. I got the the water pump and fan clutch from bulletproof diesel, hopefully this helps me. Thank you for the video!!! This is what led me to upgrade those 2 parts. 👍👍

[@grumpysdiy]

You might wanna consider an oil cooler back flush and while your there I’ve heard of people pouring clr in the oil cooler to break the gunk up.

[@parales03]

@@grumpysdiy I deleted the egr and upgraded the oil cooler through bullet proof diesel. I’m gonna drive it in the heat tomorrow. 🤞

[@grumpysdiy]

Let us know how it goes.

[@ulyoro5542]

Did you get any kind of check engine lights for switching to a mechanical fan clutch?

[@grumpysdiy]

No dash light, but if you put a scanner on the truck it pulls two electric fan codes. But it does not change the way the truck drives.

[@antn8387]

you know you can wire up a switch to the stock electric clutch fan, right?

[@grumpysdiy]

👍🏻

[@grumpysdiy]

But why would you want something else that could go wrong? The likelihood of a mechanical fan clutch failing over an electrical fan is significantly less. For instance, I could be in the mountains and the electrical fans go out. Then I’m stuck. At least with a mechanical fan clutch, it will work. Even if broken, to some capacity.

[@fergy486]

@@grumpysdiy just did the upgrade and I already see a difference my electric clutch failed a week ago hauling our trailer had to stop several times to cool it down so I’m looking forward not to have a problem

[@grumpysdiy]

I am very happy with mine, did you also do the water pump upgrade?

[@fergy486]

@@grumpysdiy nope water pump is brand new not gonna fix something that’s not broke when it decides to crap the bed I’ll change it out

[@connorcunningham2333]

How often is your fan actually engaged? I did the 7.3 mod on mine as well but it seems to be engaged majority of the time, even when the ECT and EOT are below 180*.

[@grumpysdiy]

Yea my fan clutch is always engaged. There is a sacrifice to be made here, the noise for cooler temps. Since we tow a lot I’m okay with it.

[@ruralbuckeye1200]

What do your transmission temps look like with this fan installed?

[@grumpysdiy]

Very cool

[@ruralbuckeye1200]

@@grumpysdiy could you do a video showing transmission temps also while towing?

[@grumpysdiy]

Sure thing, we are leaving for a trip again in a few days. Don’t for to subscribe so you don’t miss it.

[@grumpysdiy]

I towed our camper for 12 hours yesterday and the TFT never went over 160
