Radiators with auto trans coolers

[CarterKraft]

Look at this fuel cooler, no idea how much it helps or how much it can dissipate but it's really tiny.

Or how about the engine oil cooler, mounted to the side of the oil pan. I won't comment if that's a good idea or not but there it is.

 

[NOODLES]

Lol. You are a funny dude.

 

[NOODLES]

So you bring up a bunch of bull like "not enough room at the front" and then show a bunch of pics of coolers that are mounted in other areas. These can also be done in other areas and collect airflow still. Post more pics of your super duty. Got any with the cab lifted off the frame?

 

[CarterKraft]

This is what I get for trying to talk tech...

If you want to talk tech post up I'll do my best to repsond,research etc.

 

[NOODLES]

Sure. Don't use the shitty cooler built into the radiator. There you go.

This is the transmission cooler for a 2022 F-Superduty with 6.7 diesel and 10 speed trans. It's rate for a lot of towing weight, and a lot of HP and Torque.
The trans cooler is 13" long, 2 1.2" deep and 3" wide. The trans cooler lines are very short and a electronic valve is installed to bypass the coolant around the cooler to regulate temps.
I can find the older version (6 speed) for around $90 on the web and its more universal, cut off the fittings and weld on AN adapters.

It's not that I didn't know about them. I just didn't know they were that cheap.

I've been using marine coolers for years.

Use it for a preheater for the waste oil you should be burning?

A change I've noticed, the oem's used to bring the fluids to the "cooling pack" for cooling, now they bring the coolant to the components.

My Cummins’s oil cooler is bolted to side of the engine block inside the cavity where coolant is flowing through (near the return from radiator)

Most likely oil pressure is more than cooling system will have, so oil enter the cooling system.

Most ideal case scenario, as the cooling system is much more forgiving.

That's pretty standard for engine oil coolers to fubar the cooling system. Some cascade detergent shines her right up though usually.

I'd like to avoid the milkshake at all costs but Im not sure it's always worth the struggle for a 1 in xxxxxxx failure.

Think about the rubbers involved.

When you're talking the scale of millions of vehicles systems that pump 200deg, 15pis glycol around are going to be more long lived per dollar than systems that pump around 250-300deg 20-70psi oils.

Until you shut it down and the residual pressure in the cooling system relieves itself into the oil system.

Bit of a derail with oil in the cooling system.
Old truck driver had a head gasket seeping, so he replaced the coolant with diesel. Ran it for a couple of years that way. Said all the hoses held up, and the cooling system was CLEAN when he finally fixed it right

If I tried that I'd just blow a hose running down the interstate and die in a fireball

 

[TrailTamer]

IowaOffRoad imagine if the head gasket sprung a new leak… into cylinder. That’ll be a diesel runaway

I thought of that, but I'd rather blow it than die in a fire if it were me. That said, I think it was a decently late-model truck, most of em have silicon hoses now so maybe the hose-blowing potential is... overblown?

I don't give a fuck why they changed it it. I just noticed that they did.

Shitbox Ranger got a new radiator a year or so ago, the original lines were leaking and I didn't feel like fucking with them so I bypassed the radiator cooler ran it straight to the air to atf unit in front of the rad.

This happens with Ford diesels without even trying. Just wait for those injector cups to go. Viola. Diesel coolant.

Lost a transmission in a really nice R51 pathfinder 10 years or so ago due to the heat exchanger sucking in coolant.

Replaced the tranny (took 3 junkyard units before finding one that the ECM & TCM computers would talk nicely to each other )

Threw a new radiator in and en external cooler instead of the heat exchanger = REALLY hard cold shifts.

Plumbed back into the heat exchanger and back to shifting smooth as silk, so they definitely do their job well (until they don't).

I may get flamed for this, but I have never heard of, or experienced any kind of failure in an automatic trans from being too cold. On the other hand, too much heat is the number one cause of tranny failure. So the idea of helping it warm up is stupid to me. I like the hot water for a shower idea. Probably the best use for the “cooler”.

I've heard of that with a gas engine but just run engine oil for coolant. Guess it's not all that uncommon just not as efficient.

Power steering could be ran through one of those coolers.

👀 been watching. Waiting on aluminum 4row to show up anytime now. Plumbed for auto transmission ... liking the use of two coolers ...as well as hot water shower idea/ general cleaning..
