Installed/How-To: 2014 Forester XT OEM Oil Cooler(pics!)

[RelentlessGT]

Hi dj2020.

These oil regulators are used on the WRX STIs (turbo) and the Forester Turbo Diesels so I think the regulator probably does enough heat transfer. The question is whether the radiator can dispel that much heat. The answer is that you should try it and see. Get a cheap OBD2 reader and log the results to see if it is working (and hopefully publish them here for other people).

A good trick is as soon as you have finished driving hard turn on the Air Conditioner as it will engage both the radiator fans and you will be able to dispel much more heat whilst moving slowly.

Cheers

Kraftwerks supercharger with upgraded radiator and mishimoto thermostat. Coolant temp sits at 170ish F with oil sitting at 185F. I will do more testing when I get time. I hope the lower opening temp will allow the radiator to stop a run away oil temp.

Anyone here running this cooler via the throttle body lines? Have you noticed any improvements in keeping temps down? Logic says the oem way will be better as the TB lines are too small, but I'm trying to gather more reviews to see how the "easy" setup compares to the oem setup in terms of overall performance.

I have one installed and ran to the TB lines.. here's a 3rd log- http://datazap.me/u/koa/3rd-pull-stg...t86sfv2-012516

otemps don't veer past 215 even after 10-15mins of 3/4 load runs

This oil cooler operates better with a lower temp thermostat as bigger radiator as expected. The oil temps are 15F higher than coolant temps on average and the cooler coolant temps are able to bring oil temps down. Now I don't know if there is a runaway if oil temps get too high, but I will have to test on the highway soon.

Ambient temps were 75F, this is city driving.

Logs via TB method in Winter. I back off for a lap when I see 248/120. So once running that means 1 hot lap, one slow lap, repeat.

For AT owners, consider simply plumbing the cooler in series before the ATF heat exchanger (on the water side of course), or just the TB. It's better than nothing. No T fittings either way. Obviously the lines are much longer from down near the ATF HE, so the pressure won't be great.

I have an air/ATF cooler in series on the oil side, before the ATF HE.

Don't go deleting the ATF HE (tempting). It's does barely any cooling, it's mostly for warming the AT up faster (important).

Don't waste money on a huge, expensive radiator for NA when t-stat is barely open, unless you log 203F/95C.

Don't get a lower temp t-stat and dropping your coolant temp below what the engineers designed for the block.

The good news for lower t-stat is it looks like the ECU gives you full timing above 140F, but that would need to be tested and logged.

So, what's the difference between these two? 14050AA970 OR 14050AB090 - PIPE, WATER

[CARNZ]

AB090 was a substitute for AA970 because of huge backorders when this was initially written. Since then, supply of the AA970 pipe has been consistent, I left the AB090 pipe up there for reference.


AA970 = early 2014 FXT, AB090 = late 2014-present FXT

They should be basically the same pipe, I've looked at newer FXTs and haven't noticed a difference.

Any updates in potential alternative parts now that the 2015 WRX has been out for a while?

Its the same as the Forester.

I didn't see this in the thread, but would a local auto parts store have the generic 3/8" and 1/2" heater hose? Anywhere I see it online, the shipping is as much or more than the actual parts.

Would have really loved to use this upgrade but i can't as the allen fitting sits right where the turbo's oil return passes by. Looks like im stuck with the cusco for triple the price. Unless anyone knows of any alternatives

You can replicate Cusco kit.
That is what I did. I even spent less money than OEM kit.

Care to elaborate, any specific couplins to connect the coolant hoses, banjo bolts?
