Well, my iol cooler is a little leaky, and all dinged up, and just generally looking like ***. I could probabally just clean it up really well, bend all the fins straight, and get some of those nice ss oil lines and be set, but I came accross some of these on ebay:

They come in 19 and 13 row. What are your thoughts on them doing a better job cooling the oil than the stock? Don't worry about mounting, and some adapters would have to be come up with, but any thoughts on that question?

They don't list the brand. I'd stick with Setrab or Mocals. The Mocal 25 row 225 series will fit very well in an FD (I have two!). Not sure about a 2nd gen. You always get what you pay for!

Racing Beat says the stock coolers are the best you can buy. Go to AMERICAN COOLER SERVICE, Inc. for a FAA company that will make your cooler look better than new for less money than a new one.

get mocals if u dont want to stick with stock ones, the fins on the mocals are a lot harder to bend and they are only 50 bucks more than the ebay ones.

yeah, mocals do look sturdier in that sense. Another idea I just ran across on ebay is this:
http://cgi.ebay.com/ebaymotors/ws/eB...MEWA%3AIT&rd=1

Something similar to that. Do you think the antifreeze is cool enough to help cool the oil? Because when I feel the radiator hose after driving, it's usually pretty damn hot, opinions?

Bah, scratch that idea. In the end I think that would only be adding more heat load to the engine coolent, focing it to cool more in the radiatior, adding more heat to the engine, although taking some of the oil... There is probabally a point of diminishing returns and deadly side effects to the engine by doing that one way or another. Opinions?

Actually, I know a guy who was running an oil/water cooler on an EProd car... said his coolant temps were running too low and oil temps too high, so it worked well. But that in addition to, IIRC, the Mazda competition oil cooler.

Does anyboy have the dimenstions of the stock oil cooler? If I go with something at least somewhat bigger or the same, that should do me, right?

19 row mocals or the ebay ones they look similar, but we all know looks can be deceiving

i have a question, what size fitting do i use for oil inlet/outlet off of the block? I am using
-10 ss lines

Dick Elliott

# 10 lines work just fine after the thermostat in the cooler is removed and the hole pluged. Use all straight ends if you can.

But still, I can't find dimensions of the stock cooler anywhere, and I can't just go and see it right now as it's at home right now, and I am at ETA school. Does anybody know?

hey imhard are u going to use one stock and one new one? thats what i'm trying to do once i find the right fittings.

dick elliot, why remove stock thermostat? thats the one on the bottom of the cooler by where the lines connect to the cooler right?

How do you plug the the themostat hole?

Here's a pic of the Mocal 19-row oil cooler (and t-stat).

Well acctually I was thinking of using a new one by itself just to avoid the mess I would have to clean up, but I think I'll just add one to the loop. This is in part of not knowing what size the stock one is(dimensions). So I can't know if they will be the same cooling surface area. Again, does anybody know?

Btw, funny:

No specific dimensions, but the pics on this page might help:

ooops, I'm sorry. I never did specify which one did I? I am speaking currently of the 2nd gen oil cooler, sorry. Although that was pretty cool, I did not know 3rd gen oil coolers were so small...later

Running an EProd car in the SE. We tried one of those water to oil coolers and almost baked the engine. This thing came off of an ARCA car and was fine for it. We had oil temps close to 275 F when the driver backed off an coasted the last lap! The water temp never got above 200 F We now are running 2 stock coolers plumbed in parallel. We modified the stock banjo fittings to accept AN stuff. Running them parallel is important to get the most from the set-up. This way you have the greatest temperature differential from oil to air in both coolers.

Could you please post some pictures? And how do you tell if one stops flowing? Just as a precaution, you know, like somehow one gets clogged, so only one flows, but you woulden't be able to tell because pressure would still be the same...

Btw, I saw this really cleaned cooler on e-bay, but they said their uncle had them done, so they don't know where he had them done. Darn! It looked like new, said they were cleaned with "ultrasonic cleaning", what they use for cleaning and flushing airplane coolers. Recomend anywhere that does this, or cleans coolers in general? thanks...lateR

anyone else notice that ebay site was run by jews?

If I remember correctly, the fittings needed on the oil filter neck, front cover, and the stock cooler are 18mm to 10AN...it's been a while so a search might be in order. I used two 25-row Mocals which work very well with the FEED Type II front end.
