Coolant in rear end

[EdGs]

HOT GARBAGE. What a joke. I hope some dumba$$ engineer gets fired for this, whipped with his beloved coolant line, and shoved into purgatory.

Exactly. Some a$$hat engineer trying to justify his salary. "But boss, look at this, across the entire RAM fleet, we could save 3 gallons of gas over a year. Hurry, send this to Bob over at the EPA so he can koochy Koo us for saving the planet." *THROATPUNCH*

Tell us how you really feel Damn that was funny,best comment of the day

Absolutely the best comment!

But, you wanna know the irony of all this? The a$$hat engineer probably got a fat raise and a promotion for coming up with this crap! That's how my twisted mind works.....lol.

Well I solved it…. Down the road with it. FCA can take a hike. 6-8 months for parts. Dealer made a good offer on a 3500 but I’m not willing to take a chance. Maybe ford is better.

It’s only on 3.21 rear end

They are all making $hit products plagued with problems. They aren't being held accountable by the consumers. People just "forget" that a brand screwed them long and hard and go buy another because of some misplaced brand loyalty. Quality is a thing of the past. Product integrity died with it. If I thought I had an alternative to this RAM that was better, it'd be down the river already. I've been through GM, Ford, and Toyota.

I guess one thing I might be missing is this system may also act to keep the differential temps from going above a certain point under load by exchanging heat with the radiator or whatever they are using to circulate fluid through it.

I owned a 2017 Shelby GT350 for a few years and it had separate circulation systems with pumps, heat exchangers and thermostats to cool the transmission and the differential. Some of the early models lacked these as they were an option initially. And then the forums were rife with complaints from guys who took them to the track, the differential or transmission would overheat after a lap or two and the computer would put the car into limp mode. Lawsuits were being discussed so Ford ended up making them standard equipment in short order. So that may be the real purpose of the system - to keep lube temps from sky rocketing under heavy loads and towing.

There used to be some good trucks made.

I had my '87 F150 with the 4.9-6 for 31 years, and spend less on repairs in all that time than one or two of today's new truck payments.

1 radiator, 1 heater core, 1 fuel pump, 2 rebuilt calipers, 2 front rotors and pads, and a couple of tune ups.

I forgot I did replace the bushings on the I-beams along with radius arm bushings. That was still less than $200.00 for that.

That is it. I gave it to my oldest son this year, who is still using it when needed.

Catching up on this one and wouldn't you know, the Banks rear diff AD (different rear end of coarse) is popping up for me.......

In that scenario it absolutely makes sense to put cooling into play for all fluids. I've even seen brake fluid exchangers that impart cooling (race cars). But a half ton pickup? HARD PASS.

That inline 6 was/is a beast. They run forever and ever with basic maintenance. I've seen them well into the 300k range running just about everything "as built" from the factory.

Those were actual coolers,this isn't a cooler,it heats the diff fluid,it's not designed to cool the fluid.

It is a heat exchanger. It will heat the diff fluid when the temp is below the coolant temp, and it will help to cool the diff fluid if/when it rises above coolant temp. I'd be curious to see what the inside of the diff cover looks like to get an idea of how effective it might be as a head exchanger.

They claim it as a heat exchanger,but i'm like you,i'd like to see the inside of the cover,as i doubt it has a big enough surface area to actually reduce the diffs temps.Throw in the fact the engines thermostat on paper should be keeping the diff at 203 or higher,which is a bit on the high side for diff fluid in my opinion

I don't care what anyone says those 351w's were bulletin proof in 90's fords, oh Canada. I had 3 and my top vehicles ever up there with my ram.

The 80's and 90's roller cammed 302's were another bulletproof engine.

My brother had a regular cab shortbox 89 with the 4.9/300 six with a 5 speed in it,he couldn't kill it as a kid,and he tried,lol. He'd probably still be driving it,if it hadn't be totalled when somebody ran into it while parked on the street.
The truck was actually fairly spirited for a six,i was always amazed at how good it ran,when ever i drove it,and the 5 speed made it fun,

That's the upper end to be sure, and not something I would ask to have on my truck. So glad mine doesn't.

I'm waiting to see if the rear end warrenty claims increase because they're heating the fluid,lol

 

[Marshall]

I read this and thought it must be April 1 or a new blinker fluid post.
What a stupid idea, again.
Sound like more recalls that can't get fixed because no one knows WTH to do and no parts anyway.

PS , Fords, bought a new 1980 6 5sp? or 4 on the floor. it was a overdrive, great milage, about 30mpg. Hi optioned ,it had a radio.
great truck, wife hated the mushy stick, But at 60km it started to use a bit of oil, and it was never worked hard, so sold it. I think new price was $3k.
