Hi,
Just wonder that how large of the oil cooler size from 95' EJ25 DOHC N/A? Compare to EJ22 which one is bigger? And if compare to SVX which one is bigger?
Thanks

You are talking about the oil cooler that spins into the spot between
the oil filter and engine case, yes?
Not too many of the USDM engines have the coolers that I've worked
with. I installed a Forester (2004) that had the oil cooler which I
removed because I couldn't easily find a way to plumb the coolant
lines without interfering with the smallcar engine carrier.
The oil coolers for impreza 2.5's that i've seen have been around 77mm
in diameter by 42mm in depth. Not sure about svx's or ej22's.
all the best,

Hi,
We live in Thailand and there are many of us , T3 EJ25 , have the same problem - the engine's head and overheating.
That make me wonder that the heat exchanger ( oil cooler ) was too small.
I installed the oil-temp-guage to my 95' EJ25 n/a and I ve seen that oil temp went above 110C ( 230F ) but the VW 's water temp display so low , under the led. This always happen when drive in high speed , 4000+ rpm.
This water temp gauge fools the driver that the engine still fine , but it is not.
So I wonder that maybe subaru use the same size of oil cooler inside both 22 and 25 n/a. And the bigger one in newer engine.

I have used the thermal plate out of a Volvo 740 turbo and plumed the external oil cooler. The thermal plate bolts up were the stock subaru water/oil cooler sits. It opens at 95c and cools the oil. There were early subaru turbos that used the water/oil cooler, the problem is they dont work quick enough to cool the oil under boost or in your case under load.
There are some thermal plate being marketed at the wrx crowd. do a google search.
The svx i have didnt have anything but the filter,but its getting an external cooler.

Hi for whatever it's worth.. I don't think any amount of oil cooler will make much of a difference in EJ35 coolant cooling. Some factors ... one, if the radiator is pretty old ..it's due. The only failure mode I ever see in these radiators is they just fail to remove heat well eventually. ( or course there are tricks like other radiators that are bigger, have more rows of tubes and fins etc. ) Make *sure* the cooling system layout is correct. I use a minor variation of the basic Kennedy ( KEP ) system..works just fine for me on every conversion. Make sure the coolant is going through the radiator the correct direction ! Sometimes, to increase initial circulation I will drill a small hole on the edge of the thermostat. That doesn't really improve cooling on the hot end of things of course. Don't run a really hot thermostat of course. And use Water Wetter .. it actually works...and is standard in all Vanagon work that I do .........especially in the warm months.

Thank you , Scott,
Most of subygon in Thailand installed with simple reversed water manifold , but instead of heater circuit , we replace with LPG 's heat exchanger.
Many people here already replace new rad core. Better but problem still exist , warm coolant but very hot oil.
Google researching about adding external oil cooling ( oil to air exchanger ) tell me that it can reduce only a few degree , which might not worth its cost.
However , I ll try to run on pure gasoline and shutting off the heater 's circuit to see any difference.
I will report soon

On my vw turbo diesel ,with the same type of oil/water cooler, I would see oil temps in the 250-290 degf on long pulls under boost, and the pressure would drop to 25lbs.
With the external cooler and Volvo plate it might get to 200 on a hot day(+100 deg f) but only for about a minute.most of the time the oil is at 185-190 and pressure holds at 45-50lbs.
The other thing you could do is update the oil pump to a 10mm or the 11mm pump found on the later 2.5's.The extra volume may help when the oil gets hot and thin.
OR add a cooler from the water pump to the oilcooler?.
I have to say even with the problem you are a lucky man to be driving a vanagon in one of the most beautiful places on the planet!!

Thank you for your very kind words , jcl. Upgrading oil pump's size is a good advice. I would see for local supplier.
