Value of original 72 911S oil cooler

[ktm450exc]

Hey guys
Several months ago I purchased a 74 911 (that I may or may not roll back) that I have been getting into shape. It has a external oil cooler installed with a Troutman thermostat. The exsisting lines look used up and I decided to replace them with new elephant lines and a stock Porsche thermostat. When I explanied my current oil cooler configuration to Chuck at Elephant he said that it sounded like I had an original S cooler. Well it looks like I do indeed have that early cooler and rock shroud ( although the rock guard has had a small section cut out). The connectors seem to be 30x1.5mm. I've been told the early S coolers had smaller connectors.

Its in great maybe excellent condition. What's the value of this cooler and any other info would be appreciated
Thanks

Pix please. If it is original with 30mm fittings, 72 only, it's pretty rare.

MB,

If you're right, and if it's good, you have a very rare part indeed.....

As you've said the '69-'71 small radiator type had small fittings. The '72 was the same small radiator type cooler but with the later bigger fittings. In '73 the factory changed to the 'trombone' type cooler.

I've have a retro fitted '72 cooler on my '73 for the last 25 years. A few years ago I had and took the opportunity to buy another (with both stub lines) to keep as a spare.

I have not heard of another '72 cooler for sale for some time........

Hope this helps...

Your cooler should look like this:

Thing looks choice! . . .

. . . + I never knew about this being a '72-only bit




LOVE this site, You Guys

How did that survive in that condition. Your PM box is going to fill up very quickly.

Well this 74 I bought appears (if I follow the records and work performed) to only have about 30k on a rebuilt motor and it's a good bet the cooler was installed then, late 70's to early 80's. This owner (PCA member in NorCal) took very good care of the car, stored in a garage etc. so I wouldn't be surprised if this cooler only has 25 to 30k miles on it from installation to now.

What would you guys think is the range for value?

Chuck, would be the same concept as Elephant's "widemouth" cooler? Larger fitting's to keep the temps down..

I had no idea about the difference also..When I had my '72 S motor rebuilt, the cooler and lines were removed, cleaned and pressure tested..My '72 Targa NEVER gets hot..
