I have a Koyo radiator with an auto tranny fluid cooler inside but am using a man trans. CAN I use this cooler for engine oil instead of purchasing, plumbing and installing an aftermarket cooler? Thanks, Eric
Oil Cooler Question
- Thread starter Wendigo
- Start date
Effectivness is greatly decided by the current capacity of my wallet divided but my need to eat and my desire to consume frosty beer. Should I just reinstall my stock oil cooler?

Here is what you can do that will improve your cooling ability. (Assuming your using the stock bypass cooler that runs off the filter mount and then dumps back into the pan.)
Run it like stock, to your air to oil cooler. (The stock one.)
Then before you dump it into the pan, run it through the cooler on your radiator, then into the pan.
This will do two things.
On very cold days, your oil can be too cold, and running it through the radiator will keep it at the right temp, not too hot, or not too cold.
On hot days, the air to oil cooler will drop the oil temp first, and the water to oil cooler in your radiator does not have to work as hard to maintain the oil at the right temp.
If you look at newer Toyota's, most of them have a water to oil cooler for these very reasons. (You want the oil to be about 180 to 200f all the time, it works better at this temp, and it's able to vaporize water in the oil, a major source of contamination in most oil.)
Have fun. (My setup has a thermostat on the cooler, so it only flows through the cooler when it's over 180f. Actually, 90% bypasses, and 10% flows all the time, but it goes exactly the opposite at temps over 180f from what I understand.)

OOOooooo I like that one!! I have enough tubing to do it(buying more crap for this rebuild is starting to get REAL painful!!) Man, I want this machine to live. My coworkers, family, friends, and girl are SICK of me talking about it! SOON!!!

I have seen many people on here say they use it. My question is how can you get the volume throught the very small Inner Diameter holes in the fittings in the radiator when the through holes in most of your oiling filtration system is 1/2 ID minimum? And on Everything Aftermarket Oil Cooling.

I believe it has more to do with trying to fit the flow of a river through a water faucet kinda comparison.

Rick: The stock bypass cooler has a few small orifices so total flow isn't that much.
(Or everytime you hit 40 psi the pressure would drop to 0
)

here's a good oilfilter relocation/cooler thread:

Do you have accurate oil pressure, oil temp and water temp gauges? That way you can see before and after temps/pressures, if you do go ahead with this. I'd be very careful about messing with engine oil temps and pressure. Why not just service the heck outta your cooling system and leave well enough alone? My $0.02

What? Accurate temps on what and why?
See that last post where the new style cooler that Toyota uses on many of their new engines just runs coolant from the engine to regulate the oil temp, not over cooling it, or under cooling it...
By running his BYPASS oil cooler lines through the air to oil cooler FIRST, then running them through the radiator cooler section SECOND, he's getting much the same effect. The coolant in the radiator will be somewhat cooler than the coolant in the engine, but it's better than running things the other way around and hopeing that ambiant air temps on very cold days don't cause a problem of producing oil that is too cool.
Also here is one other thing to keep in mind.
All the oil from the stock setup goes back into the pan. A pan that just a few inches away, has a very high speed spinning crank, rods and other moving stuff that is pretty effective at mixing up this new cooler oil with the existing hot oil in the motor.... It's not like he's cooling all his oil flow, then dumping it into the main galley where it could cause real problems if it was too cold all the time. (Like is the problem with people running relocation kits and no thermostat in the lines/cooler.)
