Oil Coolers

[Rick Cabell]

I have 73S #787, it's a Italian car and DID come with a factory oil cooler. That and sport seats were the only options.

I think you guys nailed it. The radiator style fender mounted cooler was standard on "S" models from 1969 through 1972. It was an option on the other models. In 1973, Porsche went to the fender mounted trombone cooler, and it was optional on all models.

Just stumbled upon this thread- for mine 73 S #0709 build date 12/72- No external oil cooler but I have seen the provision for holding the tubing along the right side.

My 73 911S Targa (Production 9/72) has a front Oil Cooler. Originally a trombone type but I changed to a 72 Radiator type... The front oil cooler was standard on ALL "S" car prior to 1973 when the front cooler became an option... Porsche was trying to keep the cost down... A five Speed trans was also an Option...

My 11/10/72 build car also has the front cooler which has been changed out to a later carrera type. I've been considering swapping back to the trombone as the car never gets over 185 or so.

2/73 build 1973S. No oil cooler at delivery. It was an option in North America. Cars that came with the trombone cooler would have mounting brackets for it in the fender well. As well as clips under the rocker for the oil lines.
I did source all the parts for a 1973 trombone install and had all the brackets welded into the bare tub. Call it insurance for my engine rebuild....

all 73S european cars came with a trombone cooler standard. The US importer VW of America decided that it could save a few pennies by making them optional in the US.
In my part of the country Not having one was not an option. I started with the original trombone, insufficient, turbotrol marginal, and finally the 28 tube cooler which finally did the trick.
Even if you don;t get Texas temperatures sustained high speed running in 85 or so degrees the car will run too hot without a cooler.
Too hot as so aptly defined by the late Bruce Anderson.

My Italian S, 11/72 #538 came with front trombone. Gordon

Guys,

I second what David said above. About 10 years ago I had a conversation with PCNA on this subject. My contact said that trombone oil coolers were automatically added to 73 european S cars due to their propensity for high speed driving. US 'S' cars got an oil cooler only if you asked and, I guess, paid for it. "No ask, no get".

My 73 S came with factory/dealer air and Sportomatic, but no oil cooler. I have since added a factory stock 73 trombone oil cooler system that I found in a (metaphorical) trash pile. It was discarded by some one who wanted to "update".
