Default 3 questions about 2000 2.5RS Cooling/oil system

I just took my car to the track the other day and made a couple observations.

1. My oil temp on my autometer gauge reached 245-250F. Is this bad. Running AMSOIL 5W-30.

2. After about 15 laps I came in and noticed in my coolant overflow tank that there was a thin layer of tiny bubbles(looked like beer head) white foam.

3. I had the coolant overflow tank at the "FULL" line before track time, then at the end of my session the coolant in the overflow tank was about 3"inches from the top? Using OEM Subaru blue coolant

If your tracking your car 5w 30 is too thin an oil, go to a 10w 40 at least for the summer.

the coolant was 3 inches from the top or 3 inches from the full line?


any smoke or anything alse wierd?

oil level at the begining and at the end?

yes 250 is real hot for a NA car your probably pushing hard for too long, an oil cooler is definatly something you should get.

Thanks man.

Coolant was 3" from the top of the bottle

No smoke or weird smells

Oil level did not change at all.

Oil cooler sounds like a good start.

250F for the oil is perfectly fine. (And I'm not sure what the car being N/A or turbo has to do with the temperature being too high or not. ) I've seen as high as 270F or so. Adding an oil cooler wouldn't be a bad idea, but it certainly isn't necessary. Adding the OEM oil-to-water cooler on my car dropped my peak oil temps from ~270F down to ~250F.

As for the coolant, on most overflow bottles (not sure about your year/model) there are 2 FULL lines - one for COLD and one for HOT. If the car is cold and the coolant in the overflow is already at the FULL-HOT line, then it's not surprising that it would end up a few inches above that when you come off track.

Thanks Pat, good write up. Can you tell me about the OEM oil cooler? Can I get one at my local dealer? Is it easy to install? Will it fit a 00 2.5RS?

The OEM oil cooler came on the Forester (I think) and on all the '02+ turbo cars. Not sure if the newer N/A cars come with the cooler, too.

Install isn't all that difficult, but does require you to drain all the coolant and at least remove the oil filter (so you might as well change the oil while you're at it). There's a good writeup on scoobymods.

That thread lists all the parts separately, but if you talk to one of the popular online dealers (Annapolis Subaru, subaruparts.com, etc) and ask for the OEM oil cooler kit, they should know exactly what you're talking about. I would imagine they could get you the kit cheaper than your local dealer, even accounting for the shipping and you being up there in Canuck-land.

That cooler will not work with a Borla header. Just a heads up

If you plan on doing trackdays often try an external oil cooler, dont waste your time with the factory one.

there are many kits available.

your motor will thank you
