914-6 Oil Cooler Differences Options

[sixnotfour]

different manufacture.. different last 2 digtis

So here is the problem IMHO with OEM 914-6 coolers. It requires you to either adapt from 30mm to whatever line your using or use OEM lines which on a conversion would be silly as the adapter is $50 to got to AN or factory lines which comes in a set of 3 that you only typically use the 2 tank to cooler lines and don’t use the 3rd line that connects to the scavenge line which is very difficult to find and does you no good if you doing a front cooler.

Basically my suggestion on a conversion is to convert a good known cooler, use AN lines much cheaper and fit better for most applications

For that exact reason I'm sending my oil cooler off today to Pacific Oil Cooler Service INC in La Verne, CA for a cleaning/pressure test then send it off to you for the modification to add the AN fitting.

I'll spend $250 for cleaning/testing, then another $150 for the modification. Assuming $50 or so in shipping, still will cost less than half of a new $1000 914-6 OEM style cooler with a $50 AN adapter.

After researching here in the forums, it sounds like Pacific Oil Cooler Service is the go-to shop for testing/cleaning of these coolers. I talked to Wayne there yesterday, sounds like he services 911 coolers frequently.

Be careful I sent them an almost new one from @mepstein and they told me it was no good. I should have had them send it back but ended up buying a new 911 one from Porsche and modifying for my car.

Good to know. Is there another reputable oil cooler cleaning/test shop? I thought there was one in central California but google isnt coming up with any hits...

Pacific oil cooler has been a go-to for ages.

Not sure. I am thinking it was a fluke

Just to be clear; the "911 style" oil cooler with the straight push-on fitting will not clear the suspension in a 914? (Picture below)



If that's the case, is it possible to have a skilled welder (*cough* @MB911 ) modify the stock 911 oil cooler to fit a 914? Or should I start shopping for a replacement cooler? The CFS #8260 looks like its made for a 914/6 conversion:

I have modified the later style 911 oil cooler with an aluminum 90* fitting that is-12AN and 3/4 NPT. You cut off the tube flush with the end of the cooler and tap it with a 3/4 NPT tap. The tricky part is you want to have it thread in all the way and point forward and about 4* down. Then you are good to go with-12 hoses and fittings.

Why not just shorten the tube and put a straight fitting on it, then use a 90 degree bend to connect it to the hose?

In short, a tight 90 degree angle restricts flow.

The curved design of the stock cooler is superior:

Don't want derail the thread on the original issue of the 01 vs 03 cooler (which I have also unsuccessfully tried to find an answer on in the past). But has anybody tried the csf cooler? I keep seeing them advertised and with what they're claiming it would be my first choice, but would like to hear some real world feedback before purchasing.

I may not have explained my idea clearly. Usw a short tube and a fitting like the one below in the appropriate size

[mb911]

This is what I suggest personally

[technicalninja]

What is the grey material on the aluminum tube that appears to be bonding the threaded hex section to the tube?

So I TIG weld the fitting on and use an industrial epoxy around that area to ensure there is never a leak

[targa72e]

If you are using AN fittings you can get ones with separate ports to use as a drain so you don't have to undo the lines.

Example.

If/when doing this again, I would definitely go with the CSF

[gereed75]

Targa72e. Nice find on that fitting. Made my own with drill and tap Works great but this premade one is trick.
