Another GREAT VIDEO bro! Diesel Tech Ron would be proud of this one for sure!! Love the detail and preparation you put into these videos too!! 👍💥💥

[@thinkfirst6431]

Diesel Tech Ron would have told you to go to Walmart and purchase one of their Hyper Tough 25" pry bars for about $10. Pull back on the belt with your left hand and use the pry bar to lift the tension holding tab into the locked position. That 25" pry bar is one of the top 5-10 tools needed for working on the Ford 6.0L engine. Once you get the hang of it you will use it for all kinds of things. I always have one in the truck. Ron was a little rough with his, he had the experience to know what to do, had the parts to fix things that broke.

[@ryanteter]

We have a late 04 with 180k on it. Been 100% reliable because of these types of simple upgrades. Good advice. You’re a great mechanic I’d let you work on my truck.

[@walterbuelnahandymanservic2336]

[@pks2634]

Have you ever seen the plastic water pump impeller chewed up by ripples in the front cover? My front cover has a corduroy pattern that chewed up the impeller. The impeller cracked and caused an overheat condition while traveling 70 mph on a 50Fdeg day with no load.

I appreciate the details and video shots of exactly what you’re doing. Great work! I had a leaky radiator so I also updated to the 7.3 fan and also did the blue spring and banjo bolts while I had everything out of the truck. It’s already bulletproofed so the water cooler had already been swapped. I look forward to catching your other videos to see what else I need to spend my money on, lol. Thanks again!

Hey brother, what year is the new 7.3 fan clutch? I want to order it and do that mod to mine.

[@007.3l]

Watch that thermostat housing o ring, had one start leaking on cold days on my 06, thought it was the coolant pump or the big donut o ring, also the 7.3 fan clutch will set a soft code / pending code due to no wiring being hooked up P0528 comes to mind, also a coolant leak of any amount will cause cavitation

[@josephryan1576]

I wondered about that also. What options are there to prevent the code from being there, other than putting the wired fan clutch back in place?

[@haleyy68]

Replaced my coolant pump on my 03 6.0 at 218,000. Had zero pitting on front cover. Smooth like new. Not sure why people say its normal to have pitting in that area.

[@LeftLaneDiesels]

haleyy68 when the block was being made, ford sent sand through all the cooling passages to make them smooth. They did not do a good job of cleaning afterwards which is why oil cooler fail, because the sand clogs up the cooler passages. This same sand can also get irritated by the water pump spinning and can erode away at the front cover. A second reason that it is common is from cracked egr coolers or headgasket failure. Introducing air bubbles into the cooling system. Again these air bubbles get irritated by the water pump spinning and can eat away at the front cover.

[@josephcirelli9642]

Great “how to” video! I have a ‘05 F350 that I use to tow my 30’ Travel Trailer. Been thinking about changing out the water pump & fan clutch as a preventative maintenance measure.

Great video.. I bought an 04 Excursion 6.0 to tow my Jeep to wheeling events around the country. I noticed it was pretty loud when the RPMs were up it got loud.. Fan clutch was stuck engaged.. spinning non-stop. Faster you go the louder it to. Luckily I started looking on KZbin and seeing everyone doing the 7.3 conversion. So question.. When you go mechanical fan clutch what do you do w/ the wiring? If it’s unplugged will it keep sending a code?

[@jftopsfoerster4144]

Disregard about the CODE.. seen one of the other responses and answer you gave about a soft code. thanks.

Love your videos bro...very informative, you give just about every detail about the jobs your doing to leave out any guess work.

Hey man ive been a long time viewer, really loving the content lately! I don't wanna seem like one of "those guys" in the comments section and you probably were already thinking of this but it might be a good idea to replace that cold side intercooler pipe with a metal one, ive seen those plastic ones crack and create bad boost leaks.

Did you get any check engine light and reduced power not having the electric fan clutch plugged in? Is there a tune to avoid this

I was wondering about this myself. I know if the harness gets cut up in the fan it will throw a MIL and can cause the trans not to shift.... So was anything needed to prevent the MIL and keep the trans shifting?

[@cdyoude]

Is there any way you could throw in some part numbers for the water pump, 7.3 fan clutch and the BP adapter. I have a 2005 6.0 F250 and this video couldn't have come at a better time as I will be replacing my water pump in the near future also.

Nice job 👍👍how long does some thing like that take

[@LeftLaneDiesels]

[@LukesGarage]

I was wondering if the 7.3 clutch set up is better than the blue wire mod. I’ve heard of guys tying into the blue wire for the 6.0 fan and grounding it through a switch, therefore being able to control the fan. Is this a better way. I know the blue wire mod is cheaper. Just curious

[@LeftLaneDiesels]

Luke’s Garage this is a debatable topic. Overall the 7.3 fan clutch lasts longer and is more reliable. The 6.0 one fails frequently, and is also known to catch and destroy the wires. I like the blue wire mod on a working fan clutch. But when the factory 6.0 one fails I opt for the 7.3 clutch conversion. Better for towing, better a/c but can be noisey and affect fuel mileage.

[@luisgonzalez3345]

After I put the 7.3 fan lot lower temps all around besides my ac and trans help plz I wanna stay with This setup

The half size rad is the real problem, 6.0 fan clutch is superior :)

[@tinosantiago1790]

Hey man nice video I’m planning the same upgrade.....wanted your opinion on this water pump verses the bpd one if there’s no diff in performance I can’t see myself paying 200 dollars more for bpd pump that being said how is this pump doing for you? Thanks for the video...

[@LeftLaneDiesels]

IMO the price you see for the bpd one is due to the fancy paint and engraving. There is no benefit, diesel site one gives you small upgrade, reliability, affordability.

Question for you. I did this to my truck and at times it always stays engaged. Even when temps are well below freezing. Or when the motor or ambient temps are cool. Any idea why this would be doing this?

[@shadowzedge5793]

It sounds like either your clutch has been frozen in engaged mode or your radiator is really getting rid of the heat like it's designed to do.

[@justinhaddon4606]

So is this normal then? I swapped in the Hayden 7.3 fan clutch and it stays engaged all the time. Definitely keeps my temps down, but the noise and slight power loss is a drag. I would like to know if this is normal though before I put another one in it.

It will set what is known as a “soft code”. Meaning when you pull codes with a scanner, it will have a code indicator the fan speed sensor is low. Soft codes, however, do not activate the check engine light.

[@staceymcclelland3206]

Got some into on that, a lot of owners do that conversion in north Texas due to the high temps and humidity in the summer. I would try extending the clutch wires and just set the clutch off to the side still plugged in. Haven’t tried it myself just a thought.

[@kylehansen2228]

I have it done on my truck and yes, there are 2 codes thrown by it not being plugged in but they do not turn the CEL on.

[@tylerkay4641]

Does unplugging the fan and using the mechanical clutch throw a code?

[@LeftLaneDiesels]

It will throw a soft code but no check engine lights. It has no repercussions.

[@robroy9793]

I have worked on Ford E450 6.0L Ford diesel engines for years in our fleet for mass transit operations. I can tell you that there is a V ref power wire, wiring to the transmission TFT sensor, of course your fan speed signal wire, ground wire and a power wire all in that same connector. You unplug that connector and you will be messing with transmission temperatures. This is cooling strategy controlled by your PCM. The TCM will send information to the PCM (his buddy) asking for assistance with controlling transmission temperatures. Of course this is a soft code and Lefty here is correct, it will not turn your check engine lamp on since it has nothing to do with emissions. BUT!!!, this can cause transmission temperature issues galore. As a master journeyist mechanic, I would highly recommend not doing this upgrade to your 6.0 Ford truck if you plan on using this for towing. For those of you that have done this... good luck and I hope your transmission holds out for you! And finally, I would only wish this engine (P.O.S. 6.0 Ford Powerstroke) only on my worst of enemies.

The problem I see here is that the A/C and transmission work differently on the 6.0. Both are computer controlled versus the more mechanical system used on the 7.3. I would think you will have much worse air conditioning performance in low speed, hot weather, driving. Ditto for transmission temps in tow haul mode. This will also set a pending code for fan speed not matching commanded. That said, those electronically controlled viscus fan clutches are pretty unreliable.

[@luisgonzalez3345]

[@kennethdrane2292]

I live down south, the electrical fan clutch is awful for the AC in slow traffic. It is controlled by engine temp and will cut off the fan if you are idling in traffic and you will sweat until you start moving. Also I plan on using my excursion to haul a travel trailer and the mechanical clutch has proven to do a much better job in cooling. I just did the conversion and wish i had done it sooner. Thanks for all the great videos.

[@americanlawdawg3609]

The electronic 6.0 fan clutch gives better mph, it lets the fan free spin when it’s not needed. I’ve never hear of the wires getting caught in the blades. The stock 6.0 fan and clutch are extremely reliable when installed properly. I guess if folks want to down grade then it’s ones own choice, I sure as hell wouldn’t do this mod, seems like a ridiculous thing to do, I mean if you have the cash then fix it, if you don’t, then wait...but don’t Mickey Mouse it man! 👍🏻
