911 S without external oil cooler/lines ?????

[J.Puppi]

hallo,

i need some help for the restoration of my car.

My 911 s targa is from 9/1972 with matching numbers. The car has

original sport seats, air condition and full leather.

The car has no external oil cooler and oil lines on the right side. Maybe

someone removed it years ago or the car was delivered without the

external cooling system?


Thank you for some Infos

I have also seen a 73 model year car here in the U.S. that never had an external oil cooler set-up. The owner spent a long time researching it, and it was delivered that way.

My 73S was not delivered with a trombone oil cooler, even though it was a Texas delivery car. It was an option in 1973 as Porsche decontented it's cars (it's why you have a foam steering wheel, not leather). I have added a trombone cooler to protect my investment in my engine rebuild and because the body is bare and the cooler mounting tabs could be welded on.

That is the way to check incidentally. Even if someone removed the cooler, they rarely remove the mounting tabs for it in the fender. So if you have no tabs, then it didn't come with a cooler.

Old Thread but here is one of the reasons the factory eliminated from oil coolers- Germany believed there was no need to additionally cool engines that loafed along at 55MPH.

From Wikipedia-
The National Maximum Speed Law (NMSL) in the United States was a provision of the 1974 Emergency Highway Energy Conservation Act that prohibitedspeed limits higher than 55 miles per hour (90 km/h). It was drafted in response to oil price spikes and supply disruptions during the 1973 oil crisis.
While officials hoped gasoline consumption would fall by 2.2%, actual savings are estimated at between 0.5% and 1%.
The law was widely disregarded by motorists, and most states subversively opposed the law. Actions ranged from proposing deals for exemption to de-emphasizing speed limit enforcement. The NMSL was modified in 1987 and 1988 to allow up to 65 mph (105 km/h) limits on certain limited access, rural roads. Congress repealed the NMSL in 1995, fully returning speed limit setting authority to the states.

I think that was a factor but the real reason was money, imagine that! Porsche realized that they could charge people for a cooler instead of just giving it to them.

Once again why 70-72S cars are so enticing. They have more intrinsic cool stuff built into them.

Actually it was VW of America who deleted the cooler for the US, penny pinchers. The ROW S cars all came with coolers. The factory was so incredulous when I went to buy one there that they sold me the whole setup for what the option cost was, I'd have to look, but I think I paid about 200 DM for lines, thermostat and the insufficient trombone.

I thought I read somewhere that all 72 and 73 cars came with oil coolers if ordered with air conditioning from the factory. Chris
