Fleece Coolant Bypass Install On 6.7 Cummins

[@noHandle1776]

If I had to guess, the little bracket or plate on top the thermostat housing is a heat shield, protecting the temp sensor underneath from the extra heat from the egr cross over tube... in its stock config anyway ;)

[@mitchjruiz]

Can you install this on an EGR equipped truck?

[@robertknull456]

Thx 4 the info on the 190 gates thermostat temp.

[@mylesswann530]

Hey Tom question for ya, Can you think of any reason why I shouldn't install this without the thermostat in the fleece housing? Edit: Edit: Draw it out, block is where the coolant is coming from, 180 opens earlier then the 190. If you have a hose connected to the cold coolant outside the block you've rendered the t-stats useless and will never reach operating temp. Water pump will flow the coolant in the entire system before any heats up. You need the modulation of the t-stat but the problem is where its located when it fails. I don't see why a full one piece (no cradle for T-stat one solid sealed piece besides the Oring in the head) stock housing plate on the back with an inline T-stat cradle on the braided AN wasn't possible. I think the service ability would've sold over better than the aesthetics of something that looks like an inline fuel filter but for a T-stat.

So one thermostat opens first than the other ? Not much even splitin hot coolant out

[@lordofwar1234]

What happens if the thermostat goes bad, how do you know, does it get stuck open. Also assuming of the thermostat does go bad can you get to the 3 screws on the fleece to change out while still on the truck.

[@j.mentzy2480]

Brian Farnsworth If the thermostat fails in a closed position, the cooling system will function like stock. Coolant will still get to the rear cylinders through the block itself, it just won't get any from the bypass. Unsure about whether you can access the 3 screws easily, but it seems that it would be the way to replace it, or just pop the whole piece off.

[@lordofwar1234]

j.mentzy 24 I was told not to use sealant around the o-ring, but tom did?

[@j.mentzy2480]

Brian Farnsworth You don't have to. The O-ring itself is plenty capable of sealing well. Just like the main thermostat housing, it only uses/needs compression on the O-ring on the thermostat to seal it. Personally, I wouldn't put any on the ring itself, but I don't see an issue with putting around the ring on the mating surface other than an unnecessary mess and the chance that some could break off and get stuck somewhere. When you install it, you can feel the O ring pop into place, and it takes some pressure to get it in (not much, but it doesnt just drop in).

[@Nathang2233]

i have used a 180 main tstat for years even now with a fleece bypass on my 06

[@TurbaTom]

What was the factory t stat? Just curious

[@Nathang2233]

Turba Tom it was 190. I've seen people in deleted 6.7s that run 180

[@TurbaTom]

I know some debate on warmer is better for a diesels efficiency. I just went with what fleece recommend to me.

[@Hank_Hickle_dayz]

Hey Tom I like the video very informative I do have a quick question for you if you have a minute I was wondering if that is a second GEN manifold relocating the turbo that far forward I have plans to hood stack my 67

[@brianlau8316]

I've been waiting for somene to do a good install on the fleece coolant bypass .. 👍👍👍👍👍

[@TurbaTom]

The wait is over my friend!

[@MegaBolens]

Will this still fit if you have an egr cooler

[@karensellars9297]

why not use the square driv threaded plugs in the back of the head thats what i am going to do Garrey in Aus

[@BiggusDickus2]

That sounds like a really idiotic thing to do

[@pbAdpcustoms]

What band is the clamp on your radiator hose at the thermostat housing

[@DasSnakeBoy]

What’s the point of installing this? Coolant where it’s needed most? Great video

[@cummins0391]

Good job Tom. Keep 'em coming brother

[@TurbaTom]

Thanks

[@justinshadle7830]

Miss your videos. R.i.p

[@frankmjr6571]

Wait, what happened?

[@Nathang2233]

@@frankmjr6571brake failure on his drag truck he crashed and passed away

[@clinton219]

Can this be installed without removing the transmission?

[@TurbaTom]

Yes

[@j.mentzy2480]

Pain in the ass, but yes.

[@tlover94]

Yes

[@austinatkins408]

Got my bracket off today trans in place... took an hour, and the bolts were not very snug. Makes the bracket seem pointless from factory.. Now I need something to reach that damn freeze plug so I can knock it out

[@coreyadams4646]

Great info, excellent job!

[@kjohnstun86]

Hey Tom love the videos. would you recomend this for a 600-650hp truck? Just trying to decide if i want to go through the trouble to install one

[@TurbaTom]

I would if your gonna be ragging on it, if just normal driving it's a coin flip

[@raydrewry6071]

very inspiring. keep up the great videos!

[@TurbaTom]

Appreciate it!

[@HamRadio200]

What temp does the bypass thermostat open?

[@failingdisciple938]

180 degrees

[@charleshung8519]

so realistically, how bad is this to do with the transmission in?

[@TurbaTom]

It's a pain. Removing the freeze plug is the hardest part

[@socalspade21]

Probably easier to pull the head 😂

[@sugargoldy]

good video do you need one of them coolant bypasses on a stock motor and what is your opinion on a transfer case support in a 5.9 diesel pickup

[@TurbaTom]

Not really needed till you crank it up a little. I have seen the t case support but other then that don't know anything about it, though I may look into it for my truck in the future

[@sugargoldy]

Turba Tom I've got a 2006 Dodge Ram 3500 Cummins motor it's got a smarty jr. on it set on the tow mode 5 inch exhaust cold air intake the Deep transmission pan and I put the transfer case support on it and it feels like there's less slop in the drivetrain I see a lot of these high horsepower Cummins trucks without that on there and they're having no problem so I probably wasted my money but the way my luck is I'd rather have it on there than not and thank you again for all the good videos you are teaching me a lot so whenever I feel like doing something to mine I'll have a little bit of a knowledge

[@krischapa7736]

Can you do a video on taking the 68rfe out and reinstalling it. Do this is my only nightmare.

[@TurbaTom]

Look back to my old video's, installing a 68 was one of the first! Also check out the 48re swap videos, the nuts and bolts of everything are almost identical

[@bigmurph5745]

are u useing a ats 48re? how comes u didn't go with fire punk, mulldoons or goerend there closer to PA

[@TurbaTom]

It is none of the above, a shop in rising sun does my transmission. If when there is a problem I drive over or pop it out and get it taken care of

[@tombielek5759]

Anyone know how hard this is on a 5.9 with a g56 trans in the way? Or do I wait till my clutch goes and put it in with the triple disk?

[@monsterram6617]

Awesome! I was going to ask you about this a few vids ago.

[@TurbaTom]

👍

[@Cacciatore7267]

Seems like you emptied all the coolant first right?

[@TurbaTom]

At least below the freeze plug on the rear of the head, otherwise a mess will be made

[@tater0909]

I gotta ask. Do you work in a power plant? The dealer and scotchbrite made me ask. I am a power plant guy myself

[@jimmygaines6485]

does anyone know what the problem is with a 2011 ram 3500 6.7 cummins, the a/c is fully charged but all i get out of the vents is hot air, how can i fix this

[@TurbaTom]

If the compressor keeps turning on and off in short cycles it could have too much refrigerant

[@k-ris1921]

check your lines, you might have a gash in a line like I did and all did was blow hot air.

[@grogers2109]

hell yeah

[@TurbaTom]

HELLS YEAH!

[@dangarcia6709]

Too much taking. Get to the point

[@mutchsnow]

enough of the cheezy music...
