Does anyone know the size of the oil filter hoses?

I am going to install a B&M oil cooler on my truck and was going to tap into the hoses that go into/out of the oil filter housing. Does anyone know the size of those hoses? I was also thinking about putting a MagnaFine in-line filter on my power steering and was wondering the sizes of those hoses too. Any help is GREATLY appreciated.
Thanks,
Ken

 

use a Mocal thermostat sandwich adapter for the oil cooler. The hoses I believe you mentioned are coolant. Mocal 3/4-16

 

Yup

 

I already have a B&G oil cooler, why not just tap into the oil line that goes into or comes out of the sandwich adapter (or whatever it is called) that already exists under the oil filter?

those are coolant lines, pull one off and see. pm me your cell and I'll show you my filter relo

 

Power steering hoses are 10mm, had a magnafine and just removed it.

As the others mentioned, the two hoses on the oil filter adapter are flowing coolant. This is how Toyota cools the oil in a towing package I believe.

If you want to cool something, and you have an automatic trans, cool that. Much better choice.

No kidding? Damn, I did not realize that. So I guess if I am going to put an oil cooler on, I would need a sandwich adapter to go in between the coolant thingy and the oil filter, right? Not sure how else I could run an oil cooler.
Thanks for that info guys, I would not have figured that out until I went to install the cooler and then it would have been "WTF????"!

That "coolant thingy" is an engine oil cooler. There is really no need whatsoever to add another unless you've got something more than the TRD supercharger on it AND are towing to rated capacity.

 

OK, so that is part of the engine oil cooling system, so if I were to install an external cooler in front of the radiator I could do like I originally though and put it in-line on one of those hoses, right? What exactly is running through those two lines?
I know it is overkill, and knowing that there is already an oil cooler in the system, I may rethink installing the B&G setup. The truck came with an external transmission oil cooler.

FWIW, I kept the oem oil cooler setup.

I installed an aftermarket transmission cooler and no longer have any trans fluid entering the radiator. (research strawberry milkshake). When the oem radiator fittings fail inside the the radiator that seal the trans fluid from the coolant, it gets super expensive to repair.

My oem trans cooler became a power steering cooler.

I really dont know how Toyota can call this an engine oil cooler for the towing package . Have a peek at the link . That thing is tiny and relies on cool air from the engine fan .

I guess it must work but I doubt very well .

That is a damn good point. I never saw the logic behind running the lines from the trans into an already hot lower section of the radiator? I am going to install an external spin on filter for the transmission fluid, maybe I will bypass that radiator trans fluid "cooler" at the same time.
BTW Why did you remove the Magnafine from your power steering? I was actually going to put one of those on as well.
I overkill on almost everything. I would rather have it and not need it than need it and not have it. But, I am really anal, so there is that...
Ken

 

I agree, same with the trans "cooler" that runs into the lower radiator. But, a lot of manufacturers have been doing it for decades, so I guess there must be some benefit.

PMK, I PMd you my info, can you send me a pic of your setup when you get a chance?
Thanks,
Ken

I installed a remote spin on trans filter long ago. It's not the idea of heat in regards to the trans cooler, more not allowing a possibility of coolant getting into the trans when those cheap fitting corrode away.

The Magnafine...I just removed it today. I noticed a loss in fluid for the PS system. I found a slight weeping around the steering input shaft area. Yes it could be a seal failing, but it does not have a ton of miles at 41k. I am suspecting the Magnafine may be impedding return flow and causing this weep. I will know if I need to pull the steering input shaft and reseal it or not in a couple of weeks.

Not sure if I have photos or not. Might check some posts of mine from a couple years back. Getting photos right now is tough without pulling it apart.

It does not rely on cool air from the engine fan, it transfers heat from the engine oil to the coolant flowing though the core supplied by the hoses in question. Since the coolant temperature is usually below 210 degrees F, it very effectively cools the engine oil within its target range of 220-240 degrees F. Overcooling engine oil is almost as harmful as undercooling, as overcooled oil will have a far higher water content from the water vapor in blow-by. Heavy duty turbocharged engines almost exclusively use a oil to coolant type heat exchanger, with very effective results.

In case anyone didn't know, 1GR's without the towing package do not even have the engine oil cooler.

 

VERY good info guys, thanks very much. The spin-on filter housing that I am going to use for the remote transmission filter has a built in t-stat, so that should be fine. I guess if I were going to put an additional air-flow oil cooler I would just need to put a t-stat in line as well, or actually, if I use a sandwich adapter I will find one with built in t-stat.
Thanks again for the info guys, MUCH appreciated!

Thanks Landphil !!!!!!

The link I used just showed the oil cooler so I figured thats all there was to the system . Didnt know it used a cooler as well .Good to know

 

I run no coolers that weren't installed in my system to start. I have a TRD supercharger, which has another large liquid to air inter cooler radiator blocking my engine coolant radiator, and I tow 5000 lbs regularly on a dclb trd sport. I've never seen excessive temps on either my coolant or my tranny (ect around 190 and tranny temps around 180-210). I'd call that a win for Toyota design. However, as others have said, if anything install a larger transmission cooler since that heat above 220 when towing up a solid grade is where our "100k" fluid will break down and cause the most headaches. Namely a new transmission if things are left alone to long after excessive heating. However, I plan on just changing my transmission fluid every 40k, it's easier than installing a new cooler and I want to do that anyways for my own paranoid purposes. I'll probably void warranty and use an amisol synthetic instead of Toyotas brew since I don't trust the "100 k" miracle fluid.

Lastly, the strawberry milkshake is a very rare problem. It was a far bigger issue when certain manufactures of small trucks (NISSAN) used plastic fittings inside the 200 degree f radiator... it's pretty easy to figure out that's going to fail fast. Our connections are a lot tougher in there, and most failures seem to happen well after the rad probably should of been replaced as a maintence item.

 

No.

Engine coolant... "Radiator water"

Yes, the towing package comes with a trans cooler and the engine oil cooler.
The engine oil cooler is not large, but honestly, it doesn't need to be. In addition to being an oil cooler, it is also an oil heater for those in colder climates... and allows 5w30 oil to be used when a 0w20 might normally be a better option. It basically works to help stabilize the oil temperature at around 200 degrees.
Same for the in-radiator trans cooler... 200 is a perfectly acceptable temperature for the trans. 250 is getting to be too hot.
The aux cooler is there because under high load conditions such as towing, the temperature may spike to levels that the in-tank cooler can't handle.

 

the mocal sandwhich adapter is a tstat with ports for lines out and in for the cooler. goes between your oil filter mount and filter. if you need a part number pm me I'll find it for you.
