Engine Compartment question

[kltarga72]

Inside the engine compartment, what are the three round holes on the side wall for? Looks factory to me. There is also one hole on the driver side.
1963 356 T-6 normal

Try googling "356 T6 Carrera engine compartment photos"

No luck trying to find a photo showing the purpose the holes are used for

Not from the factory. Possibly the car had an A/C unit installed. Or could have been to a remote oil filter/cooler plumbed from inside the fan shroud. Maybe they tried it one side first, then the other.

You may be correct about oil cooler use, I thought the same thing. I don't think it was for A/C, no sign of any mounting holes on bottom of dash. I bought this car from a club friend in 2003, he purchased it used in 1965. He never mentioned an external oil cooler or A/C. Unfortunately I cannot ask him because he passed away several years ago.

Is anyone familiar with aftermarket oil coolers that were available in the 60's through 80's?
