I don't see how the T4 engine "isn't > subject to the problem to start with." On the Type 4, the ENTIRE A/C belt system is outside the ductwork of the cooling air. The pulley is located _forward_ of the fan (it displaces the spacer-washer thing on the hub), the A/C compressor is positioned "backwards" (i.e. spins counter-clockwise, but most compressors are reversible anyway), and the belt itself passes between the engine&oil cooler and the cast fan shroud. It doesn't interfere w/ the cooling air at all. There is one possible exception to this: the 1976 Porsche 912E (not to be confused with the 1965-69 912). Those 2099 rare examples had an oddball engine in about 3 billion different ways, and I don't remember how they did the A/C thing...
