I just wanted some input on this auxiliary oil cooler.

Are the statements in the ad accurate or is it just a sales pitch?

I think the bit about the heat exchanger not being useful after a while is true. As far as the temp drop, it depends on the setup. I'd say its possible if your oil is mad hot before the cooler.

So, if I ever want to build a turbo motor with a td05 16g I should consider using this auxiliary oil cooler or something similar to it?

I would personally. What you should do though if you're undecided, is get an oil temp gauge. Put it on before you do upgrades and then once you're done, if the oil temp is way more than it was before get an oil cooler. Course if the oil temp is way more than it should be in the first place you should get one now, or better yet, try to find out why its so hot.

Good suggestions. Thanks!

So what's the "ideal" oil temperature? And what's acceptable?

Ya got me

Most oil cooler thermostats are set to a temperature similar to that of an engine coolant thermostat... I don't think it 's a coincidence; doesn't it make sense that they'd engineer motor oils to work best at the optimal engine running temperature?

It would also explain Subaru's heat exchanger as it equalizes oil and coolant temp.

So then, ideal oil temp should be 190 degrees F since our cars use the 190 degree thermostat? The ad mentions 160 degrees as normal working temp. I know the Subaru thermostat for the radiator coolant starts opening at 176 degrees. And Subaru says a 160 degree thermostat is not recommended.

Unless u are pulling 300hp + i wouldnt evn bother.

I missed this thread the first time. That cooler is a rip off. You can get an OEM one off of a Forester in a junkyard for much much cheaper. You just need the cooler itself and a water pump with the extra bung. And if you wanted to plumb in a heat exchanger, a B&M one could be had for around $50-75. The whole thing could be done for less than $200 and just as effective as that fancy all american looking one...

Yup

210 is gettin hot


Additional benifits to the factory cooler is that it warms your car up faster, it has its own T stat I beleive, and it keeps the oil and coolant close in temputure, reducing the risk of cracking heads. Less hoses to come loose break/leak, dont have to worry about rocks punchin through it, and so on.

Volvo 740 Turbos have a sandwich plate, and setrab oil cooler. I always look for em at the wreckers, and can usually get away with them for about 20 bones. Havnt tried to fit one on a soobie yet, but I bet they'd fit.

Thanks for all the info, guys. It's helping me figure out what I'll need to do.

rallitektech, what's a sandwich plate and a setrab oil cooler?

A sandwich plate goes between the oil filter, and the oil filter housing.


its an easy way to get oil to, and back from a cooler.

Setrab is an OEM manufacturer of coolers. Good Quality.

Aah, thanks for explaining!

And here comes another question, What's "HTH"--your initials or . . . .??? (Sorry if it's a silly question)

Hope that helps.
